gcc 0

Такая проблема:

стоял gcc 3.4.3, ради интереса поставил gcc 4.0. После этого захотел обратно 3.4.3, сделал remomovepkg gcc*, установил по новой 3.4.3, теперь ничего не работает:

root@linux:/distrib/cvs/fluxbox# ./configure --prefix=/usr

checking for a BSD-compatible install… /usr/local/bin/ginstall -c

checking whether build environment is sane… yes

/distrib/cvs/fluxbox/missing: Unknown `--run' option

Try `/distrib/cvs/fluxbox/missing --help' for more information

configure: WARNING: `missing' script is too old or missing

checking for gawk… gawk

checking whether make sets $(MAKE)… yes

checking for gcc… gcc

checking for C compiler default output file name… a.out

checking whether the C compiler works… configure: error: cannot run C compiled programs.

If you meant to cross compile, use `--host’.

See `config.log' for more details.
