| 879 | 3 <h2>November 7, 2009</h2> |
| 4 <p><a href=downloads/firmware-0.9.8.tar.bz2>Version 0.9.8</a> is out, | |
| 5 based on hg commit 876. (If you want to see all the changes in this release, | |
| 6 look at <a href=http://impactlinux.com/hg/firmware/shortlog/876>commits 810 through 876</a>.)</p> | |
| 7 | |
| 8 <p.The current plan is to cut one more release at the end of the month, and | |
| 9 then have the 1.0 release around new year's. This could be considered a | |
| 10 1.0-pre1, if you like.</p> | |
| 11 | |
| 12 <p>This release upgrades linux to 2.6.31.4 and busybox to 1.15.2. | |
| 13 (The uClibc version is still 0.9.30.1, they haven't had a new release | |
| 14 yet.)</p> | |
| 15 | |
| 16 <p>The old #firmware irc channel on freenode.net has been merged into #edev, | |
| 17 so go there now to ask questions about this project. (A _lot_ of | |
| 18 knowledgeable, helpful people hang there who can answer your embedded | |
| 19 development questions.)</p> | |

| 21 <h3><b>Bug tracker and roadmap</b></h3> | |
| 22 | |
| 23 <blockquote> | |
| 24 <p>The <a href=http://redmine.impactlinux.com/projects/impact>new bug | |
| 25 tracker</a> has a <a href=http://redmine.impactlinux.com/projects/impact/roadmap>roadmap</a> | |
| 26 showing what we plan to implement for the next release or two.</p> | |
| 27 | |
| 28 <p>It's also a place to file bugs, athough sending them to the <a href=http://lists.impactlinux.com/listinfo.cgi/firmware-impactlinux.com>mailing list</a> | |
| 29 is still the fastest way to get a fix.</p> | |
| 30 </blockquote> | |
| 31 | |
| 32 <h3><b>New screenshots page</b></h3> | |
| 33 | |
| 34 <blockquote> | |
| 35 <p><a href=screenshots>This page</a> lists every target, with | |
| 36 a "screenshot" of the target's boot messages under qemu, and associated | |
| 37 links to all the various prebuilt binaries for that target.</p> | |
| 38 </blockquote> | |
| 39 | |
| 40 <h3><b>Fun with static linking</b></h3> | |
| 41 | |
| 42 <blockquote> | |
| 43 <p>The cross-compiler-$ARCH tarballs are all compiled for i686 and | |
| 44 statically linked against uClibc for maximum portability.</p> | |
| 45 | |
| 46 <p>The busybox binary in the root filesystem images is now built statically by | |
| 47 default, providing a 20% speed improvement in ./configure times under qemu | |
| 48 (due to the reduced page translation overhead). You can switch this back | |
| 49 to dynamic with "BUILD_STATIC=none".</p> | |
| 50 | |
| 51 <p>Static dropbear and strace binaries for each target are also available, | |
| 52 built by the new sources/more/native-static-build.sh script.</p> | |
| 53 </blockquote> | |
| 54 | |
| 55 <h3><b>System Image interface changes</b></h3> | |
| 56 | |
| 57 <blockquote> | |
| 58 <p>The run-from-build.sh script used to set up a development environment | |
| 59 out of the build directory, but didn't provide an easy way to do so based | |
| 60 on downloaded tarballs. (You had to work out and provide extensive | |
| 61 command line arguments to the run-emulator.sh script.) This has been | |
| 62 fixed.</p> | |
| 63 | |
| 64 <p>The run-emulator.sh script in each system interface tarball is now much | |
| 65 simpler. It now looks for distccd and $ARCH-cc in its $PATH, and sets up | |
| 66 distcc acceleration automatically if it finds them. (It announces whether | |
| 67 or not it has managed to do so, and init.sh announces whether or not it | |
| 68 thinks it has distcc acceleration enabled just before launching a command | |
| 69 prompt.) So setting up the distcc accelerator should be less of a pain.</p> | |
| 70 | |
| 71 <p>Also, run-emulator.sh no longer takes any command line arguments. Instead | |
| 72 the environment variable $HDB indicates a /dev/hdb disk image to mount on | |
| 73 /home, $HDBMEGS specifies the size of a (sparse ext2) HDB image to create if | |
| 74 it doesn't already exist, and QEMU_MEMORY indicates how many megabytes of | |
| 75 physical memory the emulator should allocate for the virtual system.</p> | |
| 76 | |
| 77 <p>Each system-image also provides a simple wrapper dev-environment.sh | |
| 78 which calls run-emulator.sh with HDBMEGS=2048, HDB=hdb.img, and | |
| 79 QEMU_MEMORY=256. (These are the values run-from-build.sh used to provide, | |
| 80 and give a reasonable build environment with 256 megs of physical memory | |
| 81 and 2 gigabytes of writeable /home space.) The run-from-build.sh script | |
| 82 itself now merely adds the specified build/cross-compiler-$ARCH directory | |
| 83 to the $PATH, changes directory to the appropriate build/system-image-$ARCH, | |
| 84 and calls ./dev-environment.sh. It's 3 lines.</p> | |
| 85 | |
| 86 <p>The system images can now also automatically mount a third disk image | |
| 87 ($HDC, specifying an /dev/hdc image to mount onto the /mnt directory), and if | |
| 88 that filesystem contains an executable "init" program in its root directory | |
| 89 the sbin/init.sh script will run that instead of launching a command prompt.</p> | |
| 90 | |
| 91 <p>The new native-static-build.sh uses this HDC capability to automatically | |
| 92 run some native package builds without having to drive the build through | |
| 93 /dev/console via a wrapper script (the way smoketest.sh does). See | |
| 94 sources/more/setup-native-static-build.sh for the script which generates | |
| 95 the hdc.sqf image for this.</p> | |
| 96 | |
| 97 <p>Note that some targets (such as sh4 and powerpc) don't yet support /dev/hdc | |
| 98 due to QEMU board emulation limitations.</p> | |
| 99 </blockquote> | |
| 100 | |
| 101 <h3><b>Build interface changes</b></h3> | |
| 102 | |
| 103 <blockquote> | |
| 104 <p>The new "sources/more" directory contains scripts the end user can | |
| 105 call, but which aren't important enough to clutter up the top level | |
| 106 directory with. The buildall.sh and smoketest-all.sh scripts moved there, | |
| 107 as did the cronjob.sh used to build the nightly snapshots.</p> | |
| 108 | |
| 109 <p>The new sources/more/native-static-build.sh natively compiles dropbear and | |
| 110 strace under the emulator, and copies them out to the host through the virtual | |
| 111 network (into the build/cron-temp directory) using busybox ftpd on the host. | |
| 112 This provides an example of how to use the new HDC /mnt/init functionality | |
| 113 to perform automatic builds under the emulator, and copy the results out | |
| 114 through the network. It uses the new sources/timeout.sh wrapper to detect | |
| 115 hung builds (defined as builds that haven't produced a line of output within | |
| 116 a given number of seconds).</p> | |
| 117 | |
| 118 <p>The new BINARY_PACKAGE_TARBALLS variable (in the file "config") tells | |
| 119 the build to create a separate tarball of the binaries produced building | |
| 120 each package. (These more granular tarballs aren't shipped yet, but may | |
| 121 be in a future release.)</p> | |
| 122 | |
| 123 <p>The new SKIP_STRIP variable tells the build not to strip binaries. | |
| 124 (Add in CFLAGS=-g for enormous binaries full of debug info.)</p> | |
| 125 </blockquote> | |
| 126 | |
| 127 <h3><b>Target upgrades</b></h3> | |
| 128 | |
| 129 <blockquote> | |
| 130 <p>Powerpc and sh4 should now work fine with stock qemu 0.11.0.</p> | |
| 131 | |
| 132 <p>The arm platform now has an armv4tl target. This is a little-endian armv4 | |
| 133 eabi, for armv4 chips offering the "thumb" extension which eabi requires. | |
| 134 (The plain armv4l target is still oabi. The oabi/eabi thing is different | |
| 135 binary ABIs, a bit like Linux vs BSD binaries or aout vs elf. The eabi | |
| 136 standard is the new one, but some of the older arm hardware can't support | |
| 137 it. This takes it down as far as it can go.)</p> | |
| 138 </blockquote> | |
| 139 | |
| 140 <h3><b>Infrastructure</b></h3> | |
| 141 | |
| 142 <blockquote> | |
| 143 <p>Behind the scenes, some extensive work is going on to simplify the | |
| 144 build scripts. (The documentation's fallen a bit behind reality here, | |
| 145 but should be back up to date next release.)</p> | |
| 146 | |
| 147 <p>The uClibc miniconfigs are now automatically generated, with the | |
| 148 bulk of the config living in sources/baseconfig-uClibc and the few | |
| 149 target specific lines being appended from the UCLIBC_CONFIG variable | |
| 150 defined in the target's settings file.</p> | |
| 151 | |
| 152 <p>The other big change is factoring out lots of common code, moving it into | |
| 153 the sources/sections directory, so things like the uClibc, busybox, and | |
| 154 toolchain builds now live in one place and are called from the various | |
| 155 other scripts that need them. (This may eventually allow alternate build | |
| 156 scripts for these packages, potentially swapping out glibc for uClibc, or | |
| 157 llvm/clang for gcc. In the meantime, it eliminates a lot of redundant code.)</p> | |
| 158 | |
| 159 <p>This required lots of small cleanups, such as making the scripts now | |
| 160 consistently use the $STAGE_DIR variable for their output directory. | |
| 161 Some other cleanups were primarily cosmetic, such as moving the extracted | |
| 162 tarball cache directory from build/sources to build/packages. (Tarballs | |
| 163 live in packages, extracted tarballs live in build/packages.)</p> | |
| 164 | |
| 165 <p>The root filesystem now contains simple /etc/passwd and /etc/group files, | |
| 166 because dropbear won't work without them (not even to ssh out).</p> | |
| 167 | |
| 168 <p>Several small bugfixes (ccwrap no longer segfaults if $PATH isn't | |
| 169 exported, /etc/resolv.conf doesn't get overwritten unnecessarily by init.sh, | |
| 170 etc).</p> | |
| 171 </blockquote> | |
| 172 | |
| 809 | 173 <h2>August 20, 2009</h2> |
| 174 <p><a href=downloads/firmware-0.9.7.tar.bz2>Version 0.9.7</a> is out, a little | |
| 175 over a month and a half late. It's a larger update than usual, so the | |
| 176 release notes are a bit long.</p> | |
| 177 | |
| 178 <p>This release is based on | |
| 179 <a href=http://impactlinux.com/hg/firmware/log/807>mercurial version 807</a> | |
| 180 of the build scripts, | |
| 181 and includes <b>Linux 2.6.30.4</b> and <b>BusyBox 1.14.3</b>. | |
| 182 No new uClibc release is out since last time.</p> | |
| 183 | |
| 184 <p>Lots of little bugs got fixed. For example, this release should build on | |
| 185 Fedora 11 (and any other platform that hasn't got "which" installed by | |
| 186 default), and now supports distcc and ccache on the host (and will use them | |
| 187 automatically if they are installed).</p> | |
| 188 | |
| 189 <h3><b>Changes to build stages: new root-filesystem, cross-static, and | |
| 190 native-compiler tarballs, upgraded buildall.sh and smoketest-all.sh.</b></h3> | |
| 191 | |
| 192 <blockquote> | |
| 193 <p>The old "mini-native" stage has been renamed "root-filesystem" | |
| 194 (the same way package-mini-native became system-image last release). The | |
| 195 script names (and resulting tarballs) now indicate what each stage makes. | |
| 196 So build.sh calls host-tools.sh, cross-compiler.sh, root-filesystem.sh, | |
| 197 and system-image.sh, in that order.</p> | |
| 198 | |
| 879 | 199 <p>The old build-static-toolchains.sh script is gone, with its functionality |
| 809 | 200 integrated into buildall.sh (which now builds i686 hosted static toolchains |
| 201 for each target by default). This is implemented by two new environment | |
| 202 variables triggering optional behavior: STATIC_CROSS_COMPILER_HOST | |
| 203 and BUILD_STATIC_NATIVE_COMPILER.</p> | |
| 204 | |
| 205 <p>Setting STATIC_CROSS_COMPILER_HOST to an architecture name creates a | |
| 206 cross compiler statically linked to run on that host (via a technique | |
| 207 known as canadian cross compile). For example, the invocation:</p> | |
| 208 | |
| 209 <blockquote> | |
| 210 <p>BUILD_CROSS_COMPILER_HOST=i686 ./build.sh armv4l</P> | |
| 211 </blockquote> | |
| 212 | |
| 213 <p>Would create a tarball called "cross-static-armv4l.tar.bz2" which was | |
| 214 built to run on an i686 host, and was statically linked (against uClibc) | |
| 215 on that host to be distribution independent.</p> | |
| 216 | |
| 217 <p>Setting BUILD_STATIC_NATIVE_COMPILER to any non-empty value creates a | |
| 218 native compiler for the target (packaged as native-compiler-$ARCH.tar.bz2), | |
| 219 which is statically linked against uClibc so it can be extracted and run on | |
| 220 just about any system of the appropriate type. (So if you can get a Linux | |
| 221 shell prompt and have enough storage and memory, you should be able to | |
| 222 compile stuff.)</p> | |
| 223 | |
| 224 <p>The upgraded smoketest-all.sh script runs smoketest.sh on each | |
| 225 target built. (The smoketest.sh script attempts to compile and run "hello | |
| 226 world" natively within a system image under qemu, and indicates whether or | |
| 227 not it worked via "pass" or "fail".) Note that smoketest-all.sh now | |
| 228 autodetects which targets have been built (have system images in the build | |
| 229 directory), and smoketest.sh times out after 60 seconds so targets that hang | |
| 230 will return failure eventually.</p> | |
| 231 | |
| 232 </blockquote> | |
| 233 | |
| 234 <h3><b>Squashfs 4.0 now the default system image type</b></h3> | |
| 235 | |
| 236 <blockquote> | |
| 237 <p>The root filesystem image type is now squashfs by default. (To change it set | |
| 238 SYSIMAGE_TYPE to ext2 or initramfs, either in your environment or the file | |
| 239 "configure".)</p> | |
| 240 | |
| 241 <p>This involved upgrading the userspace squashfs support package | |
| 242 to the version 4.0 supported by the upstream kernel, and numerous small fixes | |
| 243 to work with a read-only root filesystem (with writeable spaced mounted on | |
| 244 /home and /tmp).</p> | |
| 245 </blockquote> | |
| 246 | |
| 247 <h3><b>Target upgrades</b></h3> | |
| 248 <blockquote> | |
| 249 <h3><b>ARM upgrades</b></h3> | |
| 250 | |
| 251 <blockquote> | |
| 252 <p>Lots of work on the arm targets, with the addition of a new armv6l target | |
| 253 and conversion of the armv5l target to | |
| 254 <a href=http://www.linuxfordevices.com/c/a/Linux-For-Devices-Articles/Why-ARMs-EABI-matters/>ARM EABI</a> (which used to be documented <a href=http://www.arm.com/products/DevTools/ABI.html>here</a>, | |
| 255 but ARM screwed up its website and now you have to go | |
| 256 <a href=http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.subset.swdev.abi/index.html>here</a>). The armv4l target still provides an ARM v4 | |
| 257 little endian soft float OABI target (which is "the i386 of ARM", meaning it | |
| 258 should run on just about any arm hardware, if a bit slowly). A new | |
| 259 armv4be target is the same as armv4l except big endian.</p> | |
| 260 | |
| 261 <p>A new hw-tct-hammer target supports the <a href=http://www.tincantools.com/product.php?productid=16143>Tin Can Tools hammer/nail board</a>.</p> | |
| 262 </blockquote> | |
| 263 | |
| 264 <h3><b>Updated sparc support, almost works now. (uClibc for sparc still sucks.)</b></h3> | |
| 265 | |
| 266 <blockquote> | |
| 267 <p>The sparc target has also been upgraded to the point where it now gives | |
| 268 a shell prompt. (And immediately dies with a bus error or a hang if you try | |
| 269 to do anything, because uClibc for sparc still doesn't work. The "upgrade" | |
| 270 consisted of statically linking everything because uClibc's dynamic loader | |
| 271 doesn't work for sparc.)</p> | |
| 272 </blockquote> | |
| 273 | |
| 274 <h3><b>PowerPC remains fiddly due to QEMU issues, new powerpc-440fp target</b></h3> | |
| 275 | |
| 276 <blockquote> | |
| 277 <p>PowerPC support in QEMU is | |
| 278 <a href=http://lists.gnu.org/archive/html/qemu-devel/2009-07/msg01007.html>officially unstable</a>, so although FWL's powerpc target hasn't significantly | |
| 279 changed from last release, the version of QEMU in source control no longer | |
| 280 runs it (nor the binary powerpc system images released with FWL 0.9.6) and | |
| 281 QEMU's developers do not consider this a regression. While we search for a new | |
| 282 Linux kernel .config that matches QEMU's current expectations (and await a | |
| 283 release considered "stable"), note that setting HOST_BUILD_EXTRA=1 before | |
| 284 running host-tools.sh will build a version of qemu that does run powerpc and | |
| 285 put it in build/host where run-from-build.sh can find it. (Note also that | |
| 286 building qemu from source still takes significantly longer than the rest of the | |
| 287 host-tools.sh stage combined.)</p> | |
| 288 | |
| 289 <p>A new powerpc-440fp target produces code for the powerpc 440 with hardware | |
| 290 floating point. (Theoretically QEMU's "bamboo" board emulation should | |
| 291 run this, but QEMU doesn't emulate a 440 processor yet. We compromise by | |
| 292 running a ppc440 filesystem under qemu's power mac emulation, to take | |
| 293 advantage of the ppc440 instruction set being almost a subset of full powerpc. | |
| 294 This gets us a shell prompt, but throws illegal instruction errors if you | |
| 295 try to do anything fancy.)</p> | |
| 296 | |
| 297 <p>(Note that powerpc-440fp is not a hw-target for powerpc, it's a different | |
| 298 processor instruction set like i586 vs i686. Alas, one that qemu doesn't | |
| 299 properly emulate yet.)</p> | |

| 305 <h3><b>Now using last GPLv2 release of GCC, and future plans</b></h3> | |
| 306 | |
| 307 <blockquote> | |
| 308 <p>The upgrade to <b>gcc 4.2.1</b> gives us | |
| 309 <a href=http://gcc.gnu.org/ml/gcc-announce/2007/msg00003.html>the last | |
| 310 GPLv2 licensed version of gcc</a> (thus avoiding | |
| 311 <a href=http://lwn.net/Articles/343608/>various problems</a>). | |
| 312 <a href=http://savannah.gnu.org/forum/forum.php?forum_id=4932>Make 3.81</a> | |
| 313 was already the last GPLv2 release of that project.</p> | |
| 314 | |
| 315 <p>Note that <b>bash 2.05b</b> is still intentionally ancient (to avoid the | |
| 316 bloat of 3.x), and may be replaced with busybox ash as the default FWL shell | |
| 317 in a future release. Similarly, although <b>binutils 2.17</b> was the last | |
| 318 GPLv2 version from the FSF, an upgrade to | |
| 319 <a href=http://ftp.kernel.org/pub/linux/devel/binutils/release.binutils-2.18.50.0.1>the | |
| 320 last GPLv2 release of Red Hat's binutils fork, 2.17.5.0.17</a> is under | |
| 321 consideration for a future release. But mostly the GNU compiler toolchain | |
| 322 has been upgraded as far as possible for the forseeable future, either because | |
| 323 new versions provide no significant benefits or because they're not available | |
| 324 under a license compatible with the Linux kernel's.</p> | |
| 325 | |
| 326 <p>Future upgrades to these packages will either be via individual patches | |
| 327 (maintaining GPLv2 license) or by investigating alternative non-FSF | |
| 328 packages such as OpenBSD's <a href=http://lwn.net/Articles/255558>PCC</a> or | |
| 329 Apple's <a href=http://llvm.org>LLVM</a>. In preparation for support of | |
| 330 alternate compilers, the build scripts have moved from using "gcc" to the | |
| 331 more generic "cc" for the compiler name wherever possible, but currently no | |
| 332 drop-in replacement compiler is available.</p> | |
| 333 | |
| 334 </blockquote> | |
| 335 | |
| 336 <h3><b>Implementation details</b></h3> | |
| 337 | |
| 338 <blockquote> | |
| 339 <p>Each target configuration renamed "details" to "settings", and added | |
| 340 a "description". (This makes Gentoo From Scratch's kconfig easier.)</p> | |
| 341 | |
| 342 <p>The download.sh stage now populates a "packages" directory instead of | |
| 343 "sources/packages", meaning that everything in the sources directory now | |
| 344 comes from the FWL source tarball. To do the equivalent of "make clean" | |
| 345 you can "rm -rf build", and to do a "make distclean" you can | |
| 346 "rm -rf packages build".</p> | |
| 347 | |
| 348 <p>The build no longer deletes the alt-* tarballs when UNSTABLE isn't | |
| 349 set, you must do that by hand if you want an updated alt- version of a | |
| 350 package. The packages/MANIFEST file creation can now use the extended | |
| 351 tarball information to detect git version numbers.</p> | |
| 352 | |
| 353 <p>The === bars now show the current stage name and architecture each | |
| 354 package is being built for. (Pipe the build output to grep "^===" to see | |
| 355 just the start of each new package build.) The same information is sent | |
| 356 to the title bar of your xterm, export NO_TITLE_BAR=1 if you don't want the | |
| 357 build to update the title bar.</p> | |
| 358 | |
| 359 <p>The BUILD_STATIC option now applies to all packages built in | |
| 360 root-filesystem.sh, and can be set from a target configuration's settings file | |
| 361 (as sparc is now doing).</p> | |
| 362 | |
| 363 <p>The BUILD_VERBOSE option passes V=1 to the linux, busybox, and uClibc | |
| 364 builds that otherwise sanitize their output.</p> | |
| 365 | |
| 366 <p>You can now set NATIVE_TOOLCHAIN=only to build just the compiler | |
| 367 and not the other parts (busybox, make, toybox, bash...) This is used | |
| 368 by the canadian cross steps in build.sh to create static cross and native | |
| 369 compilers.</p> | |
| 370 | |
| 371 <p>This release broke up scripts/include.sh so that script just | |
| 372 sets lots of environment variables, and now includes scripts/functions.sh | |
| 373 to define shell functions. The architecture setup (reading architecture | |
| 374 files and creating temporary directories and such) is now done via the | |
| 375 "read_arch_dir $ARCH" shell function, so merely including sources/include.sh | |
| 376 should no longer have significant side effects. Similarly, setupfor now | |
| 377 has an EXTRACT_ONLY environment variable instead of depending on a blank | |
| 378 $ARCH (which host-tools.sh has, despite wanting to snapshot source so it can | |
| 379 build stuff).</p> | |
| 380 | |
| 381 <p>Various fixes to make parallel builds work better. (So it neither leaves | |
| 382 background processes running nor kills the parent shell and closes your | |
| 383 xterm when you hit ctrl-c.) The new "killtree" shell function, | |
| 384 which kills a process and all its children and grandchildren recursively with | |
| 385 pgrep. We also build our own sources/toys/mysetsid.c program with the host | |
| 386 compiler (because the normal command line "setsid" doesn't also do a tcsetpgrp | |
| 387 on stdin so signal handling isn't forwarded to the new session). This should | |
| 388 more reliably allow ctrl-c to exit smoketest.sh and system-image.sh and such, | |
| 389 and let FORK=1 ./buildall.sh stop all its background processes when | |
| 390 interrupted. (Note that smoketest-all.sh also honors FORK=1.)</p> | |
| 391 | |
| 392 <p>The logs from buildall.sh now live in build/logs.</p> | |
| 393 | |
| 394 <p>The new config option ROOT_NODIRS avoids creating the normal set of empty | |
| 395 directories in the new root filesystem. (The old /tools support went | |
| 396 away, but a BUILD_STATIC ROOT_NODIRS build can be extracted into /tools | |
| 397 and used from there. Then either symlink "/lib" to "/tools/lib" or "export | |
| 398 UCLIBC_DYNAMIC_LINKER=/tools/lib/ld-uClibc.so.0" to add more stuff to | |
| 399 /tools natively.)</p> | |
| 400 | |
| 401 <p>The compiler wrapper (sources/toys/ccwrap.c) can now use | |
| 402 architecture-specific WRAPPER_TOPDIR values. (I.E. armv4l-cc could | |
| 403 "export armv4l_WRAPPER_TOPDIR=/path/to/directory".) This makes | |
| 404 canadian cross compiles a lot easier.</p> | |

| 694 | 407 <h2>April 2, 2009</h2> |
| 408 <p><a href=downloads/firmware-0.9.6.tar.bz2>Version 0.9.6</a> includes | |
| 409 Linux 2.6.29 and uClibc 0.9.30.1, now with support for sh4 and upgraded powerpc | |
| 410 support.</p> | |
| 411 | |
| 412 <p>The big news is the <a href=http://impactlinux.com/code/gfs/>Gentoo | |
| 413 From Scratch</a> project, which extends a FWL system image into a Gentoo | |
| 414 Stage 1 environment, building natively inside qemu.</p> | |
| 415 | |
| 416 <p>The <a href=documentation.html>documentation</a> has been extensively | |
| 417 rewritten (but needs more). The source now contains a README and each image | |
| 418 has a usr/src/MANIFEST file listing the packages it built from.</p> | |
| 419 | |
| 420 <p>The cross and native toolchains now include ldd, readelf, and | |
| 421 ldconfig. Added support for hardware targets (an unfinished example | |
| 422 of which is hw-wrt610n) that use the same cross compiler and system | |
| 423 image as a qemu platform, but build/package a different kernel to boot | |
| 424 on actual hardware.</p> | |
| 425 | |
| 426 <p>Several new build options:</p> | |
| 427 <ul> | |
| 428 <li><p><b>$SYSIMAGE_TYPE</b> defaults to "ext2" but can now | |
| 429 produce and boot "initramfs" images as well. (And squashfs, but that doesn't | |
| 430 work yet due to missing features in squashfs tools version 3.4.)</p></li> | |
| 431 <li><p>Setting <b>$HOST_BUILD_EXTRA</b> compiles qemu 0.10.1 in host-tools.sh. | |
| 432 You currently need to do this to run sh4 or powerpc, 0.10.1 has some bugs | |
| 433 needing patches. Not on by default because it takes a _long_ time.</p></li> | |
| 434 <li><p><b>$NO_CLEANUP</b> keeps source around after builds for debugging purposes.</p></li> | |
| 435 <li><p><b>$SYSIMAGE_HDA_MEGS</b> lets you control the size of the ext2 system images.</p></li> | |
| 436 <li><p><b>$SNAPSHOT_SYMLINK</b> lets the extracted source live on a different | |
| 437 filesystem than the build happens on. (Once the updated squashfs userspace | |
| 438 tools ship, build-static-toolchains.sh may be updated to use this.)</p></li> | |
| 439 <li><p><b>$CROSS_SMOKE_TEST</b> use qemu application emulation to test run hello | |
| 440 world program at the end of the cross compiler build stage.</p></li> | |
| 441 <li><p><b>$SKIP_STAGE_TARBALLS</b> don't create tarballs of each stage, | |
| 442 just populate the directories.</p></li> | |
| 443 <li><p><b>$NATIVE_RETROFIT_CXX</b> retroactively add uClibc++ to the cross | |
| 444 compiler tarball during the native build stage.</p></li> | |
| 445 </ul> | |
| 446 | |
| 447 <p>The run-emulator.sh scripts of system images have several new options, | |
| 448 do "./run-emulator.sh --help" for a list. Takes several environment | |
| 449 variables such as $QEMU_EXTRA and $KERNEL_EXTRA. Root filesystems can | |
| 450 now run in read only mode with "KERNEL_EXTRA=ro".</p> | |
| 451 | |
| 452 <p>Lots of build infrastructure upgrades. The build stages have been | |
| 453 reorganized somewhat (most noticeably package-mini-native.sh is now called | |
| 454 system-image.sh). The "sources/packages" directory has moved up a | |
| 455 directory (to separate repository files from stuff downloaded at runtime). | |
| 456 Upgrades to the cc wrapper and the USE_UNSTABLE infrastructure. Better | |
| 457 stripping of the cross compilers and system images, so everything's a bit | |
| 458 smaller. The mirror list now lives in download.sh. New buildall.sh is a | |
| 459 wrapper around build.sh. New build-static-toolchains.sh builds them under | |
| 460 qemu; set FORK=1 to build them in paralell just like buildall.sh. The | |
| 461 ext2 system images are now built at a small size with genext2fs and | |
| 462 then expanded with resize2fs (because genext2fs slows down exponentially | |
| 463 as size increases; this means e2fsprogs is built in host-tools.sh now). | |
| 464 Distcc has been upgraded, and should work more reliably now.</p> | |
| 465 | |
| 466 <p>Too many little bug fixes to list.</p> | |
| 467 | |

| 523 | 474 <h2>December 3, 2008</h2> |
| 475 <p>After several false starts (I.E. last minute bugs, yes I test this thing | |
| 476 before shipping it), | |
| 477 <a href=downloads/firmware-0.9.5.tar.bz2>Version 0.9.5</a> is out, inching | |
| 478 towards a 1.0 release. Lots of new work this time.</p> | |
| 479 | |
| 480 <p>The biggest news is uClibc 0.9.30 and uClibc++ 0.2.2. The native toolchain | |
| 481 now supports C++, hooked up to distcc and everything.</p> | |
| 482 | |
| 483 <p>The <a href=documentation.html>documentation</a> has been extensively | |
| 484 rewritten. (There's always more to do, but most of it isn't horribly out | |
| 485 of date anymore.)</p> | |
| 486 | |
| 487 <p>The packaging stage now uses genext2fs instead of User Mode Linux, so | |
| 488 the most brittle part of the build has been removed. FWL can now fully | |
| 489 rebuild itself under itself, all the way through the packaging stage.</p> | |
| 490 | |
| 491 <p>My personal website's getting a touch overwhelmed, so a higher bandwidth | |
| 492 site is now available at | |
| 493 <a href=http://impactlinux.com/fwl>impactlinux.com</a>. This should become | |
| 494 the new primary website going forward.</p> | |
| 495 | |
| 496 <p>BusyBox has also been upgraded (to 1.13.0), and the new USE_UNSTABLE | |
| 497 infrastructure allows test versions of any package to be downloaded and built | |
| 498 without forking the build scripts, so future package upgrades can be dealt | |
| 499 with as side projects without blocking other important work.</p> | |
| 500 | |
| 501 <p>The packaging stage now uses genext2fs instead of User Mode Linux, so | |
| 502 the most brittle part of the build has been removed. FWL can now fully | |
| 503 rebuild itself under itself, all the way through the packaging stage.</p> | |
| 504 | |
| 505 <p>The old forkbomb script has been replaced with sources/build-all-targets.sh. | |
| 506 with an argument --fork to build all targets in parallel, and "--fork 3" | |
| 507 to limit the parallelism. This script can run from a cron job, producing | |
| 508 a "buildall" directory with tarballs, compressed logs, and a README file | |
| 509 listing the version of each package. The environment variable USE_STATIC_HOST | |
| 510 specifies an $ARCH to create statically linked cross compilers | |
| 511 for. (The build will then try to use them for the later stages, | |
| 512 and won't get far if you specify an arch that can't run on the host.)</p> | |
| 513 | |
| 514 <p>The include.sh script has been broken up, with a new sources/functions.sh | |
| 515 containing shell functions (like download, setupfor, and cleanup) and | |
| 516 a new "config" setting the user-editable environment variables that control | |
| 517 the build. Several of these variables have been renamed and their number has | |
| 518 grown. You can now specify the colors for each build stage using the variables | |
| 519 at the end of config.</p> | |
| 520 | |
| 521 <p>Building mini-native in a Linux From Scratch style /tools directory is | |
| 522 no longer the default. Instead set NATIVE_TOOLSDIR=1 if you want that | |
| 523 kind of layout instead of a more conventional layout. (Similarly, | |
| 524 NATIVE_TOOLCHAIN=1 now enables the native toolchain, but that variable | |
| 525 defaults to enabled in config.)</p> | |
| 526 | |
| 527 <p>See the <a href=documentation.html>docs</a> for details.</p> | |
