Compiler/linker depends on missing file:
% cat fil.c
main(int argc, char *argv)
jonasbu@jonasbu-netlab:~/t % cc -o plopp fil.c
/usr/bin/ld: cannot find /usr/lib/libc_nonshared.a
cc: error: linker command failed with exit code 1 (use -v to see invocation)
How-To-Repeat: See above.
How did you install FreeBSD? It seems extremely unlikely that a normal installation of a release would be broken like this.
The problem was likely caused by installing clang from ports. This defect can be closed now.
Thanks for the information.
