Subject: Re: gfortran errors in compilation and the making
for upgraded compilers
Thanks for the mail message below.
I have checked my system as suggested. The gmp-development is installed see
[EMAIL PROTECTED] Fedora 9 x86_64 DVD]# cd Packages
[EMAIL PROTECTED] Packages]# ls *gmp*
gmp-4.2.2-7.fc9.i386.rpm gmp-4.2.2-7.fc9.x86_64.rpm
gmp-devel-4.2.2-7.fc9.i386.rpm gmp-devel-4.2.2-7.fc9.x86_64.rpm
[EMAIL PROTECTED] Packages]# rpm -Uvh gmp-devel-4.2.2-7.fc9.x86_64.rpm
Preparing... ###########################################
[100%]
package gmp-devel-4.2.2-7.fc9.x86_64 is already installed
[EMAIL PROTECTED] Packages]# ls *mpfr*
mpfr-2.3.0-3.fc9.x86_64.rpm
There is no development package for mpfr, see http://www.mpfr.org/
Perhaps I am wrong but I did do a full, new, install from a tar file to
try and beet the header file issue.
On the matter of using an object and source directory structure. This is
my standard approach.
Apologies I should have also included that line. Here is the full
invocation which shows the object and source directory separation.

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.
Copies of these libraries' source code can be found at their respective
hosting sites as well as at ftp://gcc.gnu.org/pub/gcc/infrastructure/.
See also http://gcc.gnu.org/install/prerequisites.html for additional info.
If you obtained GMP and/or MPFR from a vendor distribution package, make
sure that you have installed both the libraries and the header files.
They may be located in separate packages.
