The GMP package contains math libraries. These have useful functions for arbitrary precision arithmetic.
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 ...
The default settings of GMP produce libraries optimized for the
host processor. If libraries suitable for processors less capable
than the host's CPU are desired, generic libraries can be created
by appending the --host=none-linux-gnu
option to the configure command.
Prepare GMP for compilation:
./configure --prefix=/usr \ --enable-cxx \ --disable-static \ --docdir=/usr/share/doc/gmp-6.3.0
The meaning of the new configure options:
--enable-cxx
This parameter enables C++ support
--docdir=/usr/share/doc/gmp-6.3.0
This variable specifies the correct place for the documentation.
Compile the package and generate the HTML documentation:
make make html
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
The code in gmp is highly optimized for the processor where it is
built. Occasionally, the code that detects the processor
misidentifies the system capabilities and there will be errors in
the tests or other applications using the gmp libraries with the
message "Illegal instruction". In this case, gmp should be
reconfigured with the option --host=none-linux-gnu
and rebuilt.
Ensure that at least 199 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
