Laster command line was the following : ../gcc-9.1.0/configure --enable-languages=c,c++,go && make && make install Now I install isl dependencies ! ISL is an optional dependency, you don't need it. Please read https://gcc.gnu.org/wiki/InstallingGCC and ensure you either install dependencies using your system's package manager, or use the ./contrib/download_prerequisites script. Then I launch again ‘configure’ command line 😊 You should start in an empty directory each time you run it. If you run configure and the build fails, and then re-run configure with different arguments or different environment, it's likely to fail again. Remove everything in the build directory and start clean each time.
