GCC 4.7.0 compiling problem Ubuntu

[Erotavlas_turbo@xxxxxxxxx]

Hi,

I have installed libc6-gdb libc6 libc6-dev-i386 package and after recompiling nothing is changed.

Inside this folder there is no config.log: this file is present in $BUILD/$target/libstdc++-v3. But I can't find nothing related to the error.
So now I'm trying to compile without --enable-libstdcxx-debug.
