I ran into a problem trying to build the 4.5.0 GCC release with GMP and MPFR placed directly in the source directory. During the GCC build process, GMP compiles fine, but MPFR fails with the error message: checking for recent GMP... yes checking for gmp internal files... configure: error: header files gmp-impl.h and longlong.h not found I put the most recent MPFR (3.0.0) in an "mpfr" directory and the most recent GMP (5.0.1) in a "gmp" directory, both in the main GCC source directory. This same technique worked for previous GCC 4.5 snapshots, but it isn't working now for the release itself (which I checkout from SVN by its tag). This is all on an up-to-date Karmic machine. (Also, I am using a separate build directory.) Any ideas what might have gone wrong? Thanks!
Does it work if you use mpfr 2.4.2? They changed the way --with-gmp-build works in 3.0.0 and there have been reports that this is incompatible with what the gcc build system does.
