0005714: bug with jamvm + concierge + classpath - BusyBox Bug and Patch Tracking

Notes
(0014104) tpetazzoni 10-24-08 06:55	The problem at the beginning is that it tries to link with the host libjpeg instead of the target libjpeg. Not sure why, though, and I don't really get why setting TARGET_DIR would solve the problem.

(0014114) Correa 10-24-08 10:35	It did build ok for me using avr32 as target. I'm using latest svn (r23778 at the moment). Try updating. There were changes in the Makefile.autotools.in that might affect your build.

(0014414) sylvain 10-28-08 02:05	Thanks for the help. tpetazzoni you are right to modify the TARGET_DIR do not resolve the problem permanently, I was just lucky and I don t know why.. (Correa) I tried to update my release, unfortunatly I have the same bug... I should have a a difference with your linux settings... That's stuff are not really easy to solve... I did other investigations to understand the problem. In fact, when I compile classpath, it compiles its dependences : libjpeg, libtiff, etc.... And inside tiff's makefile LIBTOOL try to resolve the dynamics shared libraries and it resolve -ljpeg by /usr/lib/libjpeg.so instead of <mycrosscompilToolchain>/usr/bin/libjpeg.so ... I try to understand libtool and resolve the problem but the libtool script are more or less a nightmare to understand. If you have some idea you are really welcome :-))

(0014444) tpetazzoni 10-28-08 02:35	After the failure, what's the contents of build_<ARCH>/staging_dir/usr/lib/libjpeg.la ?

(0014464) sylvain 10-28-08 03:28	I found a hack to correct my problem it's quite "dirty" but this time I can reproduce it. libtool when it tries to resolve the compile flag "-ljpeg" (it's use by tiff/port, tiff/tool, tiff/libtiff) looks inside the /usr/lib/libjpeg.la the install directory of the jpeg library which is "/usr/lib/". so it translate "-ljpeg" -> /usr/lib/libjpeg.so... If I change the last line of the file : # Directory that this library needs to be installed in: # libdir='/usr/lib' libdir='<path to your cross-compile toolchain>/usr/lib' the full compilation is alright and my embedded jvm and osgi works sucessfully !!! Now I need to understand which buildroot compilation variable I have to change for libtool in order to set the correct libraries path.

(0014474) sylvain 10-28-08 03:38 edited on: 10-28-08 03:41	(tpetazzoni) I came back to my old settings with the correct path inside /usr/lib/libjpeg.la and I reproduce the bug. 1 thing (maybe important to resolve the bug) is that I changed the destination directory of the toolchain and the kernel header to "/home/sylvain/FSEmbarque/maChaineDeCompil2/". It s not anymore inside "build_<ARCH>/staging_dir/". so my libjpeg.la contains : # libjpeg.la - a libtool library file # Generated by ltmain.sh - GNU libtool 1.2 # The name that we can dlopen(3). dlname='' # Names of this library. library_names='libjpeg.so.62.0.0 libjpeg.so.62 libjpeg.so' # The name of the static archive. old_library='libjpeg.a' # Libraries that this one depends upon. dependency_libs='' # Version information for libjpeg. current=62 age=0 revision=0 # Directory that this library needs to be installed in: libdir='/home/sylvain/FSEmbarque/maChaineDeCompil2/usr/lib' It looks correct... thanks for the help.

(0014484) tpetazzoni 10-28-08 08:53	Hm, strange. Will try to reproduce it here to see what goes wrong. BTW, my name is Thomas Petazzoni, and I'm the colleague of Michael Opdenacker, at Free-Electrons. Didn't you meet him two weeks ago during a training ?

(0014504) tpetazzoni 10-28-08 16:03	Ok, I tried to reproduce your issue without any of the patches I currently have on Buildroot (with my patches, I'm not able to reproduce). However, without my patches, I face the following problem during libtiff ./configure: checking for inflateEnd in -lz... no configure: error: Zlib library not found at /home/thomas/local/buildroot/build_arm/staging_dir/lib Could you try with the patch I'll attach to this bug ?

Yes I gonna try. I have to duplicate my buildroot folder before, I post when I finish.

(0014544) sylvain 10-29-08 02:00 edited on: 10-29-08 02:00	Ok I tried the patch and it correct my bug !!! Thanks a lot. WARNING : don t forget to declare in your PATH "STAGING_DIR/usr/bin"

(0014554) tpetazzoni 10-29-08 04:09	Hum, interesting. I'm not sure why the patch I provided fixes the bug. However, you mention that you must add $(STAGING_DIR)/usr/bin to your PATH. What fails if you don't do that ?

(0014574) sylvain 10-29-08 07:11	>Hum, interesting. I'm not sure why the patch I provided fixes the bug. for sure now I can compil busybox +classpath + jamvm + concierge without any problems when I apply the patch... >However, you mention that you must add $(STAGING_DIR)/usr/bin to your PATH. >What fails if you don't do that ? You can forget this remark. I was not really awake when I write this... I did a mistake this morning... You don't need to add the PATH of you cross-compiler in your environments. Anyway I try several times with the patch, with or without the PATH, without modify the /usr/lib/libjpeg.la, and I get a full files system for ma board, with operational OSGI.
