It seems like file's objects are is trying to link against an ABI incompatible libc and failing. The build system should handle this properly if you invoke the top-level targets (buildworld, buildkernel, distribution). This is trickier than you think: the error occurs during the build-tools stage, where everything that builds still uses the host's toolchain and libraries (e.g. the 7.x versions). So if you try to build a program that uses getline(), it will not be able to link. This is what happens with the 'mkmagic' tool. However, this will have started failing just very recently, since obrien updated to a new file(1) version, and regenerated the config.h file: http://svnweb.freebsd.org/base/head/lib/libmagic/config.h?r1=208341&r2=234449 Maybe some hackery could be inserted in lib/libmagic/Makefile, so during the early stages a 'toned down' config.h file is used. The libmagic source has its own getline implementation in contrib/file/getline.c, so maybe that could be used instead. On the other hand, going from 7.x to HEAD via the 'official' route would go like: - Update 7.x to the latests 7-STABLE - Update 7-STABLE to 8-STABLE - Update 8-STABLE to 9-STABLE - Update 9-STABLE to 10-CURRENT It is *way* easier to just grab a recent 10-CURRENT snapshot ISO and just reinstall. :)
