In trying to debug an unrelated problem, I switched CC from Clang
back to GCC. I had a -current kernel and world r247050 built and
installed with Clang as the system compiler I have nothing special
in /etc/make.conf:
BATCH=yes
WITH_NEW_XORG=true
WITH_KMS=true
WITH_PKGNG=yes
PERL_VERSION=5.14.2
I added WITHOUT_CLANG_IS_CC=yes to this, then rebuilt kernel and
world. I installed the kernel rebooted, everthing worked, so I
then installed world. Installword stopped here:
===> libexec/rtld-elf (install)
chflags -h noschg /usr/libexec/ld-elf.so.1
install -s -o root -g wheel -m 555 -C -b -fschg -S ld-elf.so.1 /libexec
install -o root -g wheel -m 444 rtld.1.gz /usr/share/man/man1
*** [_maninstall] Signal 11
Stop in /opt/FreeBSD/current/src/libexec/rtld-elf.
*** [realinstall] Error code 1
At that point my system was completely hosed. Every binary (/bin,
/sbin, etc) would sig 11. I had to build a world on another
system, then use /rescue to NFS mount the other system and
copy over /libexec, /lib, and /usr/lib. This let me recover
enough to svn up to r247164. remove WITHOUT_CLANG_IS_CC from
/etc/make.conf, and build/install a working world.
Is switching from Clang to GCC suppose to work?
