[SOLVED] Re: build GCC 12.1 failure on namespace from /usr/include/stdlib.h

[Guy Moebs <guy.moebs@univ-nantes.fr>]

Hello,


I have solved my problem and managed to compile gcc 11.3.0 and 12.1.0 
completely.

In the output of the configure command I read :

configure: WARNING: using in-tree isl, disabling version check

So I add it to my configure command which is now

../gcc-12.1.0/configure --prefix=<path_to_install_dir> 
--disable-multilib --enable-threads=posix 
--enable-languages=c,c++,fortran,go --disable-isl-version-check


and everything works fine.

Regards,

    Guy.
