As you already messed up the sources, better get fresh ones. > http://gcc.gnu.org/install/configure.html Done all that, still the error persists: $ ls gcc-9.2.0 $ mkdir gcc-9.2.0-build $ cd gcc-9.2.0-build $ ../gcc-9.2.0/configure --prefix=/tmp/chroot-gcc/usr/ --enable-bootstrap --with-glibc-version=2.12 --with-newlib --without-headers --disable-nls --disable-shared --disable-multilib --disable-decimal-float --disable-threads --disable-libatomic --disable-libgomp --disable-libquadmath --disable-libssp --disable-libvtv --disable-libstdcxx --enable-languages=c,c++ ... Configuring stage 2 in ./gcc ... checking for log long... yes checking size of long long... configure: error: in `/tmp/sources/gcc-9.2.0-build/gcc': configure: error: cannot compute sizeof (long long) ... The exact same error in the config.log.
