I'm trying to build a custom 11-STABLE release for a machine that is too wimpy to self-host using the /usr/src/release/release.sh script. The build host is an amd64 machine and the target machine is is in the i386 family. I've set: TARGET=i386 TARGET_ARCH=i386 in the release.conf file. If I don't try to specify a CPUTYPE, I have no problems. But if I add CPUTYPE?=pentium3 to the make.conf file, the release build fails like this: -------------------------------------------------------------- >>> stage 4.2: building libraries -------------------------------------------------------------- ===> gnu/lib/libssp/libssp_nonshared (obj,all,install) ===> lib/libcompiler_rt (obj,all,install) ===> gnu/lib/libgcc (obj,all,install) error: unknown target CPU 'pentium3' --- ssp-local.o --- *** [ssp-local.o] Error code 1 This is the same message that I get if I try to compile something on amd64 if I specify -march: %cc -c blah.c -march=pentium3 error: unknown target CPU 'pentium3' but I don't see this when I do the same on an actual i386 machine. I'm assuming it is because pentium3 is not valid amd64 family member. It seems like I should be able to avoid this by telling clang that I want to cross-compile, but clang doesn't seem to like the -arch command line flag: %cc -c blah.c -arch x86 -march=pentium3 cc: warning: argument unused during compilation: '-arch x86' [-Wunused-command-line-argument] error: unknown target CPU 'pentium3' %cc -c blah.c -arch i386 -march=pentium3 cc: warning: argument unused during compilation: '-arch i386' [-Wunused-command-line-argument] error: unknown target CPU 'pentium3'
