https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D239266 --- Comment #5 from Leandro Lupori <leandro.lupori@gmail.com> --- Created attachment 205872 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D205872&action= =3Dedit gcc8 vec_step fix Ok, with the attached patch I'm able to go further in gcc8 build. But then when xgcc starts to be used, I get errors, because xgcc is generat= ing ELFv1 code and trying to link with ELFv2 libs. I've tried to fix this by passing -mabi=3Delfv2 in CFLAGS, with the followi= ng Makefile change: 65c65 < MAKE_ARGS+=3D CFLAGS_FOR_TARGET=3D"-O1" CXXFLAGS_FOR_TARGET=3D"-O1" BOOT_CFLAGS=3D"-O1" # PR235975 --- > MAKE_ARGS+=3D CFLAGS_FOR_TARGET=3D"-O1 -mabi=3Delfv2" CXXFLAGS_FOR_TARGET= =3D"-O1 -mabi=3Delfv2" BOOT_CFLAGS=3D"-O1 -mabi=3Delfv2" # PR235975 The build then goes further, but fails with the following error: gmake[7]: Entering directory '/usr/ports/lang/gcc8/work/.build/powerpc64-portbld-freebsd13.0/libgomp' /bin/sh ./libtool --tag CC --mode=3Dlink /usr/ports/lang/gcc8/work/.build/./gcc/xgcc -B/usr/ports/lang/gcc8/work/.build/./gcc/ -B/usr/local/powerpc64-portbld-freebsd13.0/bin/ -B/usr/local/powerpc64-portbld-freebsd13.0/lib/ -isystem /usr/local/powerpc64-portbld-freebsd13.0/include -isystem /usr/local/powerpc64-portbld-freebsd13.0/sys-include -Wall -Werror -Wc,-pthread -O1 -mabi=3Delfv2 -lpthread -Wl,-O1 -o libgomp.la -version= -info 1:0:0 -Wl,--version-script,libgomp.ver -rpath /usr/local/lib/gcc8 alloc.lo atomic.lo barrier.lo critical.lo env.lo error.lo icv.lo icv-device.lo iter.= lo iter_ull.lo loop.lo loop_ull.lo ordered.lo parallel.lo sections.lo single.lo task.lo team.lo work.lo lock.lo mutex.lo proc.lo sem.lo bar.lo ptrlock.lo time.lo fortran.lo affinity.lo target.lo splay-tree.lo libgomp-plugin.lo oacc-parallel.lo oacc-host.lo oacc-init.lo oacc-mem.lo oacc-async.lo oacc-plugin.lo oacc-cuda.lo priority_queue.lo openacc.lo -ldl=20 libtool: link: /usr/ports/lang/gcc8/work/.build/./gcc/xgcc -B/usr/ports/lang/gcc8/work/.build/./gcc/ -B/usr/local/powerpc64-portbld-freebsd13.0/bin/ -B/usr/local/powerpc64-portbld-freebsd13.0/lib/ -isystem /usr/local/powerpc64-portbld-freebsd13.0/include -isystem /usr/local/powerpc64-portbld-freebsd13.0/sys-include -shared .libs/allo= c.o .libs/atomic.o .libs/barrier.o .libs/critical.o .libs/env.o .libs/error.o .libs/icv.o .libs/icv-device.o .libs/iter.o .libs/iter_ull.o .libs/loop.o .libs/loop_ull.o .libs/ordered.o .libs/parallel.o .libs/sections.o .libs/single.o .libs/task.o .libs/team.o .libs/work.o .libs/lock.o .libs/mutex.o .libs/proc.o .libs/sem.o .libs/bar.o .libs/ptrlock.o .libs/ti= me.o .libs/fortran.o .libs/affinity.o .libs/target.o .libs/splay-tree.o .libs/libgomp-plugin.o .libs/oacc-parallel.o .libs/oacc-host.o .libs/oacc-init.o .libs/oacc-mem.o .libs/oacc-async.o .libs/oacc-plugin.o .libs/oacc-cuda.o .libs/priority_queue.o .libs/openacc.o -lpthread -ldl=20 -B/usr/ports/lang/gcc8/work/.build/./gcc/ -B/usr/local/powerpc64-portbld-freebsd13.0/bin/ -B/usr/local/powerpc64-portbld-freebsd13.0/lib/ -pthread -mabi=3Delfv2 -Wl,= -O1 -Wl,--version-script -Wl,libgomp.ver -Wl,-soname -Wl,libgomp.so.1 -o .libs/libgomp.so.1.0.0 /usr/local/bin/ld: .libs/openacc.o: ABI version 1 is not compatible with ABI version 2 output /usr/local/bin/ld: failed to merge target specific data of file .libs/opena= cc.o collect2: error: ld returned 1 exit status gmake[7]: *** [Makefile:594: libgomp.la] Error 1 gmake[7]: Leaving directory '/usr/ports/lang/gcc8/work/.build/powerpc64-portbld-freebsd13.0/libgomp' gmake[6]: *** [Makefile:904: all-recursive] Error 1 So apparently some objects are still being build with ELFv1 ABI. --=20 You are receiving this mail because: You are on the CC list for the bug.=
