# Setup

# This file is sourced, not run.  It provides a place for you to persisently
# set configuration variables.

# Feel free to replace this file with your own version, or to set these
# environment variables on the command line.  This entire file is optional;
# by default all the variables listed in this file are left blank.

#############################################################################

# Seting this tells build.sh not to build a native toolchain.  (This yields
# a much smaller root-filesystem tarball.)

# export NO_NATIVE_COMPILER=1

# Setting this tells root-filesystem.sh not to create the normal directory
# hierarchy of /usr, /tmp, /etc, and so on.

# export ROOT_NODIRS=1

# Setting this tells build.sh to use the existing $PATH commands to build
# everything, which probably won't work out of the box.  Cross compiling is
# an insanely delicate process which requires a carefully configured host
# environment.  If we don't set up our own, you'll have to supply one.

# export NO_HOST_TOOLS=1

# Set this to a comma separated list of packages to build statically,
# or "none" to build all packages dynamically.  Set to "all" to build all
# packages statically (and not install static libraries on the target).

# By default, busybox and the native compiler are built statically.
# (Using a static busybox on the target provides a 20% performance boost to
# autoconf under qemu, and building the native compiler static makes it much
# more portable to other target root filesystems.)

# export BUILD_STATIC=busybox,binutils,gcc-core,gcc-g++,make

# If this is set, build.sh will build a cross compiler statically linked
# against uClibc.  This indicates which host that compiler should run on.
# Note that most x86_64 systems can run a statically linked i686 binary even
# if they don't have the 32-bit libraries installed, so that's a good default.

# export CROSS_HOST_ARCH=i686

# If this is set, only build a C compiler and not C++

# export NO_CPLUSPLUS=1

# This may be set by the target's "details" file, but you can override it here.
# You can set it to ext2, initramfs, or squashfs.  It defaults to squashfs
# if blank.

# export SYSIMAGE_TYPE=squashfs

# Size of writeable HDA image (if any), defaults to 64 megs

# export SYSIMAGE_HDA_MEGS=64

# This tells build.sh to create a rw-system-image with SYSIMAGE_TYPE=ext2
# and SYSIMAGE_HDA_MEGS=2048.

# export BUILD_RW_SYSTEM_IMAGE=1

# Set this to use symlinks instead of hard links when creating temporary copies
# of the source packages (in setupfor).  This is slower and uses more inodes,
# but allows the extracted source packages to live in a different filesystem
# than the build directory.

# export SNAPSHOT_SYMLINK=1

# Use qemu to run "hello world" built by the cross compiler.  Note that this
# requires working qemu application emulation for your target to do this, which
# is significantly more brittle than system emulation.  (To unbreak qemu-arm,
# "echo 0 > /proc/sys/vm/mmap_min_addr" as root.)  You probably don't need
# to do this.

# export CROSS_SMOKE_TEST=1

# If set, try downloading packages from this location first.

# export PREFERRED_MIRROR=http://impactlinux.com/fml/mirror

# Set this if you don't want to drop all unrecognized environment variables.

# NO_SANITIZE_ENVIRONMENT=1

# If set, the toybox utilities will take precedence over busybox ones.
# (Probably obsolete.)

# export USE_TOYBOX=1

# Try development versions of these packages.  (Know what you're doing if
# you select these, it's quite possible the result won't work.)

# export USE_UNSTABLE=uClibc,busybox,toybox,linux,binutils,make,gcc-core,gcc-g++

# Debugging option to leave source in build/temp-$ARCH after build.

# export NO_CLEANUP=1

# Don't create tarballs at the end of each stage.

# export NO_STAGE_TARBALLS=1

# Tell the linux kernel, uClibc, and busybox to show the actual build commands
# instead of pretty-print output.

# export BUILD_VERBOSE=1

# Don't update the title bar in the display

# export NO_TITLE_BAR=1

# Create a tarball with the files installed by each individual package at
# each stage of the build.

# export BINARY_PACKAGE_TARBALLS=1

# Set this if you want debug symbols in your binaries.

# export SKIP_STRIP=1

# Set this to tell download.sh to extract all the tarballs up-front right
# after downloading them.  (Otherwise the tarball is extracted by setupfor
# the first time the build tries to use it.)
#
# Extracting tarballs early is useful in order to run multiple build.sh
# instances in parallel when building multiple targets, or to test that
# new patches added to the sources/patches directory apply cleanly.

# export EXTRACT_ALL=1

# If you build strange things (such as gcc 3.4 with binutils 2.14), you
# may need extra host binaries added to build/host.  This lets you add them.
# In general, you don't want to do this.

# export HOST_EXTRA="lex yacc"

# Set this to continue despite failed patches.

# export ALLOW_PATCH_FAILURE=1

# If this is set, it's points to a directory containing additional files to
# copy into the simple-root-filesystem.  The path is either absolute or
# relavitve to the aboriginal topdir.

# export SIMPLE_ROOT_OVERLAY="overlay"

# Build more things in parallel.

# export FORK=1

# Force a specific number of CPUs instead of autodetecting.

# export CPUS=1

# This isn't actually one of our variables, but a number of packages listen
# to this to add extra debug info to their binaries.  (Use with SKIP_STRIP)

# export CFLAGS="-g -pipe"
