including MPFR and GMP

including MPFR and GMP

[Jerin Joy]

Hi,

I'm trying to compile GCC 4.3.0 on a Linux x64 machine. configure
complained about MPFR and GMP which I installed. Passing in the paths
to MPFR and GMP doesn't make the error go away:

[jj155244@ gcc-4.3.0]$ ./configure
--with-mpfr=/import/dtg-data20/jj155244/tools/mpfr-2.3.1
--with-gmp=/import/dtg-data20/jj155244/tools/gmp-4.2.3
checking build system type... x86_64-unknown-linux-gnu
..
..
checking for correct version of gmp.h... yes
checking for correct version of mpfr.h... no
configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.0+.
Try the --with-gmp and/or --with-mpfr options to specify their locations.

I don't know why it doesn't pick up the correct files from the path.

Those options take the location where you installed the libraries, i.e.
the --prefix that you gave when configuring them.

The paths below look like the plain source dirs of an unpacked tarball. 
These options point to a built and installed copy of the libraries, not
a bare source dir.

It is also possible to have gcc bootstrap these libraries with itself,
in the usual manner of a combined tree.

Brian,

I had built the libraries but not run a make install because I didn't
have root access to the machine. The gcc configure was looking for the
'include' and 'lib' subdirectories for gmp and mpfr. I created a
softlink within the gmp and mpfr libs but gcc configure didn't like
it.

/import/dtg-data20/jj155244/tools/mpfr-2.3.1/include -> ../

Its working now that I ran a make install.

thanks,
Jerin
