Source is svn -CURRENT. There is no other option set than WITHOUT_CLANG_IS_CC. Beside I use MALLOC_PRODUCTION=1 This happens on both 32-capable targets, amd64 and powerpc64. I figured that there are at least three headers 'missing' so far in src/lib32/usr/include: - math.h - fenv.h - libutil.h If I manually copy them to this location I can continue building until /usr/bin/ld complains about not being configured for sysroots. I just restarted the whole worldbuild again with the above mentionend headers in place. I'll take a few minutes ;) TIA for your help! Andreas
