I checked, that the 32-bit libraries were built. That's ok!

cd /disk1/SCRATCH/gcc-build/Linux/x86_64-unknown-linux-gnu/gcc-4.1-20051112/gcc-4.1-20051112/x86_64-unknown-linux-gnu/32/libstdc++-v3/src/.libs ls -l lib* gives:

Than I checked the libstd++.log. That's the failure:

I compared this to an earlier build and I'm sure that the wrong library search path is used in this case. It should be:

/SCRATCH/gcc-build/Linux/x86_64-unknown-linux-gnu/gcc-4.1-20051112/gcc-4.1-20051112/x86_64-unknown-linux-gnu/32/libstdc++-v3/src/.libs

Any hints?

ERROR: could not compile testsuite_shared.cc

This is the important bit. The libstdc++ testsuite tried to compile a support file and failed, so it generated an error. The rest is just a tcl backtrace which we don't need.

The real question here is why it failed. There should be useful info in the $target/libstdc++/testsuite/libstdc++.log file. You probably got a linker error. One obvious question is to check to see whether you have the optional 32-bit libraries installed.
