GCC 4.7.0 compiling problem Ubuntu

[erotavlas]

Hi,

I have tried to compile GCC 4.7.0 under Ubuntu 11.10 64 bit with the following configuration parameters:

configure -v --enable-languages=c,c++,fortran --prefix=/opt/gcc-4.7.0 --enable-shared --enable-linker-build-id --program-suffix=-4.7.0 --enable-threads=posix --disable-werror --with-cpu=native --with-arch=native --with-tune=native --enable-nls --without-included-gettext --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --enable-checking=release --with-system-zlib --with-fpmath=avx --enable-lto --with-ppl --with-cloog

This is the output before the last error:

I have tried to compile GCC 4.6.3 with the same configuration parameters and it works. So there should be some change in GCC 4.7.0.

I have already asked on GCC help mailing list http://gcc.gnu.org/ml/gcc-help/2012-04/msg00099.html. They say that it is a problem of Ubuntu. It probably has changed the library libc. If I remove the option --enable-libstdcxx-debug, I can compile with success also with GCC 4.7.0. Can you help me?

Thank you

See the following similar thread , no fix yet but some things you may want to look at. gcc 4.7 has a PPA for 12.04 and can be install from there. But won't work in 11.10.

Hi,

thank you very much for your answer. I can install the GCC from package but I can't configure it to use custom plug-in and custom features.
The problem is the following: with Ubuntu 11.10 64 bit I can compile well the GCC 4.6.3 but not the GCC 4.7.0. If I remove the --enable-libstdcxx-debug option I can compile also the latest version.
The problem is related to Ubuntu and how it manages the libc libc6-dbg_*.deb.
Any help is welcome.

Thank you
