Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+

Question

I downloaded GCC 4.5 from http://www.netgull.com/gcc/releases/gcc-4.5.0/ but when I try to setup / build I am getting below error:

configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations.  Source code for these libraries 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, MPFR and/or MPC 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.
Linux:>~/shared_scripts/bin/gcc/gcc-4.5.0 1041>

The following libs are present in respective directories

/usr/lib/libgmp.a
/usr/lib64/libgmp.a

/usr/lib/libmpfr.a
/usr/lib64/libmpfr.a

I do not have libmpc.a library installed anywhere in boxes.

Based upon the error how can I know :

a) what is the current version of libgmp.a and libmpfr.a are installed.

b) If they are of incorrect version how can I deploy my own version without disturbing the current one?

Answer 1

Inside the gcc directory, do this command:

./contrib/download_prerequisites

After that script, GMP, MPFR, and MPC will be ready to use. Continue with ./configure.

Answer 2

I had the same problem trying to install/compile GCC 4.8.1. Here is how I solved:

In Debian, just run this two commands:

apt-get install libmpc-dev
./configure

Answer 3

I had the same problem compiling GCC 4.9 branch.

For Red Hat and Fedora based systems, run the following command:

sudo yum install gmp gmp-devel mpfr mpfr-devel libmpc libmpc-devel

This will install the GNU multiple-precision (MP) libraries for integer, floating point, and complex numbers.

Answer 4

In the directory where I have those libraries installed (/usr/gnu64/lib), I also have a libgmp.la file (and libmpc.la and libmpfr.la files), which contain readable text. The SO version information is in there, but that is not quite the same as the 'product version'. It tells about link compatibility instead.

I was trying to investigate which version I had, and the weird solution I came up with was to run the GCC (4.6.1) that I built with the -v option. In part, it said:

GNU C (GCC) version 4.6.1 (x86_64-apple-darwin11.1.0)
    compiled by GNU C version 4.6.1, GMP version 5.0.1, MPFR version 3.0.0, MPC version 0.8.2
warning: GMP header version 5.0.1 differs from library version 5.0.2.
warning: MPFR header version 3.0.0 differs from library version 3.1.0.
warning: MPC header version 0.8.2 differs from library version 0.9.

So, it appears that I have GMP 5.0.2 installed (but I built GCC with 5.0.1), and MPFR 3.1.0 (but I built GCC with 3.0.0) and MPC 0.9 (but I built GCC with 0.8.2). The mismatch comes about because I tried to compile and install GCC 4.6.2 and it presumably needed the newer versions. (I didn't succeed, but that's a different story.)

I install my custom-built libraries in /usr/gnu64/lib, and then tell GCC that's where to find them with the configure options --with-mpfr=/usr/gnu64/lib, --with-gmp=/usr/gnu64/lib, --with-mpc=/usr/gnu/64/lib. These paths are hard-wired into GCC and it works from there.

Centos7: sudo yum install libmpc-devel
