I put the src trees of gmp, mpfr, and mpc under the gcc tree, linked "gmp", "mpfr", "mpc" directories to each of these src trees. Then called configure, in a separate tree, as recommended. But I'm getting: checking for recent MPFR... no configure: error: MPFR version >= 2.3.1 required The MPFR version in the GCC tree is 3.1.0. What do you recommend I do?

There's a script to do that in the gcc source dir, just run ./contrib/download_prerequisites > (3) ./configure --prefix=/home/smith/GCC461 --with-gmp=/home/smith/GMP --with-mpfr=/home/smith/mpfr --with-mpc=/home/smith/mpc Do not run ./configure, see http://gcc.gnu.org/wiki/FAQ#configure > gmake > > but the -m32's are creeping in somehow. Probably when building 32-bit libs, x86_64 is a multilib platform, meaning it builds 32-bit and 64-bit libs. You could stop it building the 32-bit ones with --disable-multilib but that;s probably not what you want to do.
