6.13. GMP-5.0.1

The GMP package contains math libraries. These have useful functions for arbitrary precision arithmetic.

Approximate build time: 1.7 SBU
Required disk space: 39 MB

6.13.1. Installation of GMP



If you are building for 32-bit x86, but you have a CPU which is capable of running 64-bit code and you have specified CFLAGS in the environment, the configure script will attempt to configure for 64-bits and fail. Avoid this by invoking the configure command below with

ABI=32 ./configure ...

Prepare GMP for compilation:

./configure --prefix=/usr --enable-cxx --enable-mpbsd

The meaning of the new configure options:


This parameter enables C++ support


This builds the Berkeley MP compatibility library

Compile the package:



The test suite for GMP in this section is considered critical. Do not skip it under any circumstances.

Test the results:

make check 2>&1 | tee gmp-check-log

Ensure that all 162 tests in the test suite passed. Check the results by issuing the following command:

awk '/tests passed/{total+=$2} ; END{print total}' gmp-check-log

Install the package:

make install

If desired, install the documentation:

mkdir -v /usr/share/doc/gmp-5.0.1
cp    -v doc/{isa_abi_headache,configuration} doc/*.html \
