I suspect for kernel-only there may be a more lightweight approach (for example, by dropping c++): Env: Debian Stretch (we run in a simple official docker container with build-essential and make installed) - but probably should work on any distro Assuming the sources are extracted into $(BUILDDIR)/gcc-$(VERSION) cd $(BUILDDIR)/gcc-$(VERSION) ./contrib/download_prerequisites cd .. mkdir gcc-build cd gcc-build ../gcc-$(VERSION)/configure --enable-languages=c,c++ --build=x86_64-linux-gnu --disable-multilib make -j<something> sudo make install (or install into alternative dir and point Linux build system there) Regards, Ignat
