[Clfs-support] Cannot link libgmp while building mpfr

[Lance Chou]

It seems I'm wrong. Although the make can be done, the library is still
not generated out.

I take a look at the Makefile in the mpfr-2.4.1 directory.
When linking libgmp.so via libtool (line 426), it uses "-rpath
$(libdir)" to refer to the $(libdir) directory. But $(libdir) is set to
"${exec_prefix}/lib" where the "exec_prefix" was set to "prefix".

So, when we use "./configure --prefix=/usr" ..., it forces to search
libgmp.so in the /usr/lib directory when linking with libgmp.so.
After I remove the "-rpath $(libdir)", it can be built successfully.

But I'm afraid that it would have some side-effects if I remove it.
Besides, how come it's useless to assign "--with-gmp-lib" when
configuring.

I'm confused here, building mpfr-2.4.1 is part of III Make the 
cross-compile.

Are you sure that you have followed the guide precisely?
I would check that ${CLFS} is set, and all the other prerequisitions.
