I try with the tarball of 22/09/2008 When I compil busyboc + classpath + jamvm + concierge I get something like : libtool: link: /home/sylvain/FSEmbarque/maChaineDeCompil/usr/bin/arm-linux-uclibc-gcc -Os -I/home/sylvain/FSEmbarque/maChaineDeCompil/usr/include -I/home/sylvain/FSEmbarque/maChaineDeCompil/include --sysroot=/home/sylvain/FSEmbarque/maChaineDeCompil/ -isysroot /home/sylvain/FSEmbarque/maChaineDeCompil -msoft-float -g -O2 -Wall -W -o mkg3states mkg3states.o -L/home/sylvain/FSEmbarque/maChaineDeCompil/lib ../port/.libs/libport.a /usr/lib/libjpeg.so -lz -lm -lc /usr/lib/libjpeg.so: could not read symbols: File in wrong format collect2: ld returned 1 exit status make[3]: *** [mkg3states] Erreur 1 make[3]: *** Attente des t?ches non termin?es.... libtool: link: /home/sylvain/FSEmbarque/maChaineDeCompil/usr/bin/arm-linux-uclibc-gcc -Os -I/home/sylvain/FSEmbarque/maChaineDeCompil/usr/include -I/home/sylvain/FSEmbarque/maChaineDeCompil/include --sysroot=/home/sylvain/FSEmbarque/maChaineDeCompil/ -isysroot /home/sylvain/FSEmbarque/maChaineDeCompil -msoft-float -shared .libs/tif_aux.o .libs/tif_close.o .libs/tif_codec.o .libs/tif_color.o .libs/tif_compress.o .libs/tif_dir.o .libs/tif_dirinfo.o .libs/tif_dirread.o .libs/tif_dirwrite.o .libs/tif_dumpmode.o .libs/tif_error.o .libs/tif_extension.o .libs/tif_fax3.o .libs/tif_fax3sm.o .libs/tif_flush.o .libs/tif_getimage.o .libs/tif_jpeg.o .libs/tif_luv.o .libs/tif_lzw.o .libs/tif_next.o .libs/tif_ojpeg.o .libs/tif_open.o .libs/tif_packbits.o .libs/tif_pixarlog.o .libs/tif_predict.o .libs/tif_print.o .libs/tif_read.o .libs/tif_strip.o .libs/tif_swab.o .libs/tif_thunder.o .libs/tif_tile.o .libs/tif_unix.o .libs/tif_version.o .libs/tif_warning.o .libs/tif_write.o .libs/tif_zip.o -Wl,--whole-archive ../port/.libs/libport.a -Wl,--no-whole-archive -L/home/sylvain/FSEmbarque/maChaineDeCompil/lib /usr/lib/libjpeg.so -lz -lm -lc -isysroot /home/sylvain/FSEmbarque/maChaineDeCompil -msoft-float -Wl,-soname -Wl,libtiff.so.3 -o .libs/libtiff.so.3.8.2 /usr/lib/libjpeg.so: could not read symbols: File in wrong format collect2: ld returned 1 exit status make[3]: *** [libtiff.la] Erreur 1 make[3]: quittant le r?pertoire ? /home/sylvain/FSEmbarque/buildroot-20081024/build_arm/tiff-3.8.2/libtiff ? make[2]: *** [all] Erreur 2 make[2]: quittant le r?pertoire ? /home/sylvain/FSEmbarque/buildroot-20081024/build_arm/tiff-3.8.2/libtiff ? make[1]: *** [all-recursive] Erreur 1 make[1]: quittant le r?pertoire ? /home/sylvain/FSEmbarque/buildroot-20081024/build_arm/tiff-3.8.2 ? ====================================================================== ---------------------------------------------------------------------- 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. ---------------------------------------------------------------------- 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. ---------------------------------------------------------------------- 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 /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 :-)) ---------------------------------------------------------------------- tpetazzoni - 10-28-08 02:35 ---------------------------------------------------------------------- After the failure, what's the contents of build_/staging_dir/usr/lib/libjpeg.la ? ---------------------------------------------------------------------- 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='/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. ---------------------------------------------------------------------- sylvain - 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_/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. ---------------------------------------------------------------------- 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 ? ---------------------------------------------------------------------- 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 ? ---------------------------------------------------------------------- sylvain - 10-29-08 00:26 ---------------------------------------------------------------------- >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).

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