--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to terryinzaghi from comment #9) > cd gcc-15.1.0 > ./configure --disable-multilib Don't do this, this is not supported. The build directory must be different from the source directory. Either some directory outside of the source directory, or what also works is a subdirectory of the source directory. So ../../whatever/gcc/configure --disable-multilib or ../configure --disable-multilib or /whateverelse/gcc/configure --disable-multilib
