>Here is a list of suggested modifications to the GMP source tree to enable pkg-config to be used with GMP:
>Create a file called gmp.pc.in in the GMP src tree, it should contain the following text:

>libdir=@libdir@
>includedir=@includedir@

>Name: gmp 
>Description: GNU Multiple Precision Arithmetic Library
>URL: http://gmplib.org
>Version: @PACKAGE_VERSION@
>Libs: -L${libdir} -lgmp
>Cflags: -I${includedir}

>Alter file Makefile.am to include:

>pkgconfigdir = $(libdir)/pkgconfig
>pkgconfig_DATA = gmp.pc

>I added this at line 100, but I guess anywhere in the file would do.

>Please note that I had to issue the "autoreconf" command to enable the suggested alterations to work

>as long as you set your environment correctly (PKG_CONFIG_PATH=/usr/local/lib/pkgconfig) you should
>be able to use pkg-config to list GMP and its version number.
