This is the part in configure.ac that you are trying to trigger: if test "x$with_mpfr$with_mpfr_include$with_mpfr_lib" = x && test -d ${srcdir}/mpfr; then gmplibs='-L$$r/$(HOST_SUBDIR)/mpfr/.libs -L$$r/$(HOST_SUBDIR)/mpfr/_libs '"$gmplibs" gmpinc='-I$$r/$(HOST_SUBDIR)/mpfr -I$$s/mpfr '"$gmpinc" # Do not test the mpfr version. Assume that it is sufficient, since # it is in the source tree, and the library has not been built yet # but it would be included on the link line in the version check below # hence making the test fail. have_gmp=yes fi And similarly with gmp. Are you sure that you put the gmp and mpfr directories in the right place? ie, $(srcdir)/gmp?
