Hi,

I'm not able to emerge gcc-4.2.3 on amd64-linux (on RHEL4). It
fails both during a bootstrap process and when re-emerging within an
already existing installation. The problem seems to be located somewhere
in the multilib area:

The gcc-4.2.3/libstdc++v3/configure script, called within
build/x86_64-pc-linux-gnu/32/libstdc++-v3, is setting "gcc_no_link" in
line 2664 depending on the result of:

> configure:2664: $EPREFIX/var/tmp/portage/sys-devel/gcc-4.2.3/work/build/./gcc/xgcc -B$EPREFIX/var/tmp/portage/sys-devel/gcc-4.2.3/work/build/./gcc/ -B$EPREFIX/usr/x86_64-pc-linux-gnu/bin/ -B$EPREFIX/usr/x86_64-pc-linux-gnu/lib/ -isystem $EPREFIX/usr/x86_64-pc-linux-gnu/include -isystem $EPREFIX/usr/x86_64-pc-linux-gnu/sys-include  -m32 -o conftest    conftest.c  >&5

Unfortunately, this fails with:

> $EPREFIX/usr/x86_64-pc-linux-gnu/bin/ld: skipping incompatible $EPREFIX/var/tmp/portage/sys-devel/gcc-4.2.3/work/build/./gcc/libgcc.a when searching for -lgcc
> $EPREFIX/usr/x86_64-pc-linux-gnu/bin/ld: cannot find -lgcc
> collect2: ld returned 1 exit status
> configure:2667: $? = 1

Due to this failed run, "gcc_no_link" is set to "yes".

It's obvious that work/build/gcc/libgcc.a is incompatible due to 64bit,
but work/build/gcc/32/libgcc.a has been created.

due to "gcc_no_link" set to "yes".


Any hints are appreciated!


Best regards,
	Stefan
