Hi Roberto, > However, the problem we observe is not in the location of the library.
The problem should go away if, on Linux/x86_64 systems, you use --prefix=PREFIX --libdir=PREFIX/lib64 when installing the gmp library or, as a simple measure afterwards, copy or symlink lib to lib64. > The problem is that, passing from the version > distributed with Gettext 0.14.6 to the version distributed with > Gettext 0.15, the right -Idir flag is not added to CPPFLAGS. The AC_LIB_LINKFLAGS macro does not augment CPPFLAGS if it does not find the library. Augmenting CPPFLAGS without setting the LIBGMP, LIBGMPXX variables accordingly would only cause trouble. > AC_DEFUN([AC_CHECK_GMP], > [ > dnl Since libgmp and libgmpxx are usually installed in the same location, > dnl let the prefixes default from each other. > if test -n "$with_libgmpxx_prefix" && test -z "$with_libgmp_prefix"; then > with_libgmp_prefix="$with_libgmpxx_prefix" > else > if test -n "$with_libgmp_prefix" && test -z "$with_libgmpxx_prefix"; > then > with_libgmpxx_prefix="$with_libgmp_prefix" > fi > fi > > dnl Check how to link with libgmp. > AC_LIB_LINKFLAGS([gmp]) > > dnl Check how to link with libgmpxx. > AC_LIB_LINKFLAGS([gmpxx], [gmp]) This all OK.
