gcc-2.96 fails to compile gnustep (objc)
Last modified: 2005-10-31 17:00:50 EST
when i try to compile gnustep using gcc-2.96 as shipped with redhat 7.0 gcc exits after a segmentation fault. this is reproducable using the current gnustep version from cvs or with the last released version: ftp://ftp.gnu.org/gnu/gstep/gstep-core-0.6.6.tar.gz the following is the output of gcc (after doing a simple configure successfully first, of course): gcc NSData.m -c -DGNUSTEP_INSTALL_PREFIX=/usr/GNUstep/System -DGNUSTEP_TARGET_DIR=\"ix86/linux-gnu\" -DGNUSTEP_TARGET_CPU=\"ix86\" -DGNUSTEP_TARGET_OS=\"linux-gnu\" -DLIBRARY_COMBO=\"gnu-gnu-gnu-xgps\" -Wall -DGNUSTEP -DGNUSTEP_VERSION=0.6.6 -DGNUSTEP_MAJOR_VERSION=0 -DGNUSTEP_MINOR_VERSION=6 -DGNUSTEP_BASE_LIBRARY=1 -DGNU_GUI_LIBRARY=1 -DXGPS_BACKEND_LIBRARY=1 -DGNU_RUNTIME=1 -D_REENTRANT -fPIC -DGSWARN -g -O2 -Wno-import -fgnu-runtime -I../Headers/gnustep -I./ix86/linux-gnu -I. -I/usr/include -I/usr/include -I/usr/X11R6/include -I/usr/GNUstep/Network/Headers -I/usr/GNUstep/System/Headers -o shared_obj/ix86/linux-gnu/gnu-gnu-gnu-xgps/NSData.o NSData.m:2258: Internal error: Segmentation fault. Please submit a full bug report. See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions. make[4]: *** [shared_obj/ix86/linux-gnu/gnu-gnu-gnu-xgps/NSData.o] Error 1 rm o_list_cbs.m o_list_bas.m o_map_cbs.m o_map_bas.m o_hash_cbs.m o_hash_bas.m o_array_cbs.m o_array_bas.m make[3]: *** [libgnustep-base.build] Error 2 make[2]: *** [libgnustep-base.all.library.variables] Error 2 make[2]: Leaving directory `/home/georg/tmp/gstep-core-0.6.6/base/Source' make[1]: *** [internal-all] Error 2 make[1]: Leaving directory `/home/georg/tmp/gstep-core-0.6.6/base' make: *** [subproj-all] Error 2 as the gcc-maintainers will not support the snapshot redhat used for rh 7.0 i hope you can resolve the problem (or perhaps give a hint about the "offending" source in NSData.m).
This report is still valid for gcc-2.96-74 !
Ouch, this one was easy (garbage collection problem), sorry it took that long. The fix is at http://gcc.gnu.org/ml/gcc-patches/2001-02/msg00883.html and will appear in gcc-objc-2.96-76.
