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:

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?

try running `./contrib/download_prerequisites.sh` from the gcc source dir. It worked for me (for the current version of gcc though (`gcc-4.7`) — Sebastian, Apr 05 '12 at 04:18
The script no longer seems to have an .sh extension: `./contrib/download_prerequisites`. — Jeroen, Oct 05 '14 at 21:07
download_prerequisites.sh was added in 4.6 it looks like. 4.5.0 doesn't have it. — bobpaul, Dec 12 '17 at 19:50

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.

Was trying to install gcc 6.2 on bash on ubuntu on windows, this command worked for me. Thanks! – Emile Vrijdags Dec 10 '16 at 12:52

Thanks for that. I was stuck on a machine with no `sudo`, and this solved my woes – Arnon Apr 09 '17 at 11:58

Dead on, this should be the correct answer. Super star. – evensis Aug 25 '18 at 21:39
One thing to mention: this command must be run in the gcc source root folder, it will download the files under there, if run it in other place, configure still cannot find the correct files. – cn123h Apr 14 '19 at 15:44

Thanks. It worked for me even on really old CentOS 4 when I wanted to compile newer GCC there. – Alexander Samoylov Oct 02 '19 at 14:20
Works for me! (on centos) – Phiber Feb 04 '20 at 21:57

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

On Amazon Linux, it's `sudo yum install libmpc-devel` – Jonathon Hill Dec 28 '13 at 03:08

Centos also needs `sudo yum install libmpc-devel` – bebbo Jun 18 '16 at 20:26
On ubuntu 16 it is sudo apt-get install libmpc-dev – Jul 26 '18 at 19:31
On Raspbian 9.13 there isn't such thing as libmpc-dev – Nathan B Apr 22 '21 at 15:47

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.

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.

I tried the same step but copying .a and .la to a local folder using --with-gmp/mpfr to local folder but it stills give the same error. Also I downloaded and build gmp/mpfr/mpc from ftp://gcc.gnu.org/pub/gcc/infrastructure/ [gmp-4.3.2.tar.bz2,mpfr-2.4.2.tar.bz2,mpc-0.8.1.tar.gz] but building mpc states - configure: error: GMP version >= 4.2 required while gcc still staes the same error. — Programmer, Feb 13 '12 at 01:20
@Prakash: in that case, assume GCC and its configuration suite knows what it is doing, and get on with compiling and installing the other three libraries. I've always done it as a separate operation, without reference to GCC (even though GCC triggered the rebuilds). I believe there may be a way to get GCC to build and install the libraries as it goes - by having the source for GMP, MPFR, MPC in the GCC source tree. Check the `./configure --help` output for information. — Jonathan Leffler, Feb 13 '12 at 02:26
Since writing this, I've taken to having GCC build the version of GMP, MPFR and MPC along with the compiler. I now get the source for the current version of the library, and extract it into the top-level directory of the GCC source: gmp-6.0.0, mpfr-3.1.2, etc. Then I create a symlink for each of them: `ln -s gmp-6.0.0 gmp; ln -s mpfr-3.1.2 mpfr; ln -s mpc-1.0.2 mpc`. Then I run GCC configure and build, and GCC builds these libraries too. — Jonathan Leffler, Apr 30 '14 at 13:53

Good on you for providing an answer . FYI rather than just give an answer It would be helpful to others to tell why you would want to run that command and what it should do. It is also a good idea to ensure that you answer all of the question that is asked – Josh Oct 29 '19 at 03:16

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