This is with clang. The release tag for kernel and world is r264192. =24 cc -v FreeBSD clang version 3.4 (tags/RELEASE_34/final 197956) 20140216 Target: armv6--freebsd11.0-gnueabi Thread model: posix Selected GCC installation:=20 =24 I was not successful in compiling a gcc from the ports on armv6. ONLY_FOR_ARCHS prohibits it. After adding armv6 to the allowed architectures I ran into the binutils building problem mentioned here on the list. As I know too less about binutils my humble patches were not successful. Ralf > Is this with clang or gcc?
