You need to do: mv gcc-4.4.5/gmp/gmp-5.0.1/* gcc-4.4.5/gmp/ rmdir gcc-4.4.5/gmp/gmp-5.0.1 And similarly for mpfr. Usually I do tar xjf gcc-4.4.5.tarbz2 tar xjf gmp-5.0.1.tar.bz2 ln -s ../gmp-5.0.1 gcc/gmp I wrote a makefile to automate this recently: http://advogato.org/person/redi/diary/229.html just say: gmake -f gcc-config.mk GCC_VERSION=4.4.5 GMP_VERSION=5.0.1 MPFR_VERSION=3.0.0 (That makefile will also download mpc, needed for building recent versions of gcc, I should make that dependent on the GCC_VERSION variable)
