6.13.1. Installation of GMP
![[Note]](../images/note.png)
Note
If 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 adding ABI=32 to the CFLAGS variable for the duration of the configure
command below, then remove it afterwards.
Prepare GMP for compilation:
./configure --prefix=/usr --enable-cxx --enable-mpbsd
The meaning of the new configure option:
-
--enable-cxx -
This parameter enables C++ support
Compile the package:
make

Important
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 143 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-4.3.1
cp -v doc/{isa_abi_headache,configuration} doc/*.html \
/usr/share/doc/gmp-4.3.1
