6.14.1. Installation of GMP
![[Note]](../images/note.png)
Note
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 \
--disable-static \
--docdir=/usr/share/doc/gmp-6.1.0
The meaning of the new configure options:
-
--enable-cxx -
This parameter enables C++ support
-
--docdir=/usr/share/doc/gmp-6.1.0 -
This variable specifies the correct place for the documentation.
Compile the package and generate the HTML documentation:
make make html

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 190 tests in the test suite passed. Check the results by issuing the following command:
awk '/# PASS:/{total+=$3} ; END{print total}' gmp-check-log
Install the package and its documentation:
make install make install-html
