Sorry for the cross-post, but the problem is so weird that I'm confused what nature it is.
For complicated reasons (see below for details), I'm trying to build lang/gcc8 so that it uses gas/gld from devel/binutils instead of /usr/bin/{as,ld}. I put DEPENDS+= binutils-[0-9]*:../../devel/binutils CONFIGURE_ARGS.NetBSD+= --with-gnu-ld --with-ld=${PREFIX}/bin/gld CONFIGURE_ARGS.NetBSD+= --with-gnu-as --with-as=${PREFIX}/bin/gas in Makefile. After quite some build time, some intermediate step chokes with: checking for x86_64--netbsd-gcc... /var/work/pkgsrc/lang/gcc8/work/build/./gcc/xgcc -B/var/work/pkgsrc/lang/gcc8/work/build/./gcc/ -B/usr/pkg.compiler_boot/gcc8/x86_64--netbsd/bin/ -B/usr/pkg.compiler_boot/gcc8/x86_64--netbsd/lib/ -isystem /usr/pkg.compiler_boot/gcc8/x86_64--netbsd/include -isystem /usr/pkg.compiler_boot/gcc8/x86_64--netbsd/sys-include checking for suffix of object files... configure: error: in `/var/work/pkgsrc/lang/gcc8/work/build/x86_64--netbsd/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. gmake[2]: *** [Makefile:20348: configure-stage2-target-libgcc] Error 1 gmake[2]: Leaving directory '/var/work/pkgsrc/lang/gcc8/work/build' gmake[1]: *** [Makefile:26109: stage2-bubble] Error 2 gmake[1]: Leaving directory '/var/work/pkgsrc/lang/gcc8/work/build' gmake: *** [Makefile:949: all] Error 2 *** Error code 2 Stop. make[1]: stopped in /usr/pkgsrc/lang/gcc8 *** Error code 1 Stop. make: stopped in /usr/pkgsrc/lang/gcc8 According to config.log, the failing command is /var/work/pkgsrc/lang/gcc8/work/build/./gcc/xgcc -B/var/work/pkgsrc/lang/gcc8/work/build/./gcc/ -B/usr/pkg.compiler_boot/gcc8/x86_64--netbsd/bin/ -B/usr/pkg.compiler_boot/gcc8/x86_64--netbsd/lib/ -isystem /usr/pkg.compiler_boot/gcc8/x86_64--netbsd/include -isystem /usr/pkg.compiler_boot/gcc8/x86_64--netbsd/sys-include -c -g -O2 -D_FORTIFY_SOURCE=2 -I/usr/include -I/usr/pkg.compiler_boot/include/python3.10 conftest.c >&5 ktrace-ing that manually reveals cc1 CALL mmap(0,0x100000,PROT_READ|PROT_WRITE,0x14001002<PRIVATE,ANONYMOUS,ALIGN=1MB>,0xffffffff,0,0) cc1 RET mmap 137581005111296/0x7d2112f00000 cc1 PSIG SIGSEGV caught handler=0xa2e336 mask=(11): code=SEGV_MAPERR, addr=0x8, trap=6) I even have no idea what xgcc is. Any hints? That's on 8.2_STABLE. What I'm really trying to do is to build for 6.1 using a chroot and kver. Without the patch to make gcc8 use pkgsrc binutils, it builds and seems to work (it can build itself into the standard LOCALBASE), but it fails on archivers/zstd because gcc emits a .S file (no inline involved) which /usr/bin/as can't assemble (tzcntl and shrx). Any hints on that welcome, too!
