--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-07-01 12:50:06 UTC --- (In reply to comment #0) > ../gcc-4.6.1-RC-20110620/configure > --with-gmp-include=d:/gcc4.6.1.src/gmp-5.0.2 > --with-gmp-lib=d:/gcc4.6.1.src/gmp-5.0.2/.libs > --with-mpfr-include=d:/gcc4.6.1.src/mpfr-3.0.1 > --with-mpfr-lib=d:/gcc4.6.1.src/mpfr-3.0.1/.libs > --with-mpc-include=d:/gcc4.6.1.src/mpc-0.9/src > --with-mpc-lib=d:/gcc4.6.1.src/mpc-0.9/src/.libs What on earth are you doing here? You have not installed gmp/mpc/mpfr, you seem to be trying to use compiled-but-not-installed versions, why? It's much easier to just put the gmp/mpfr/mpc sources into the gcc source tree and then everything just works See http://advogato.org/person/redi/diary/240.html
