This is a shame, because the 32-bit library is built and available in /usr/lib32 -- cc just needs to know to look there, when given the ``-m32'' flag. >How-To-Repeat: echo 'main() {}' > t.c cc -m32 t.c /usr/bin/ld: skipping incompatible /usr/lib/libgcc.a when searching for -lgcc /usr/bin/ld: cannot find -lgcc >Fix: The details of the contrib/gcc/gcc.c appear hairy to a novice like myself, but it should not be too difficult for a seasoned developer to fix this configuration problem. Or so I think :-) Renaming /usr/lib to /usr/lib64 and /usr/lib32 to /usr/lib allows creation of 32-bit executables, but, obviously, prevents creation of the 64-bit ones (and starting many programs). This has been a nuissance since the beginning of the FreeBSD/amd64, I guess. It would be nice to see it resolved in the upcoming 6.1. >Release-Note: >Audit-Trail: >Unformatted:
