8.23 GMP-6.3.0

8.23.1 Installation of GMP

Note

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.

First, make an adjustment for compatibility with gcc-15 and later:

sed -i '/long long t1;/,+1s/()/(...)/' configure

Prepare GMP for compilation:

./configure --prefix=/usr    \
            --enable-cxx     \
            --disable-static \
            --docdir=/usr/share/doc/gmp-6.3.0

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

Caution

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:

cat $(find -name '*.log') | grep -c ^PASS

Install the package and its documentation:

make install
make install-html

8.23.2 Installation of GMP - 32-bit

Clean previous build:

make distclean

Generic libraries can be created by running the following:

cp -v configfsf.guess config.guess
cp -v configfsf.sub   config.sub

Prepare GMP for compilation:

CFLAGS="-m32 -O2 -pedantic -fomit-frame-pointer -mtune=generic -march=i686" \
CXXFLAGS="$CFLAGS"                     \
ABI="32"                               \
PKG_CONFIG_PATH="/usr/lib32/pkgconfig" \
./configure --prefix=/usr              \
            --host=i686-pc-linux-gnu   \
            --disable-static           \
            --enable-cxx               \
            --libdir=/usr/lib32        \
            --includedir=/usr/include/m32/gmp

Compile the package:

sed -i 's/$(exec_prefix)\/include/$\(includedir\)/' Makefile
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 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:

make DESTDIR=$PWD/DESTDIR install
cp -Rv DESTDIR/usr/lib32/* /usr/lib32
cp -Rv DESTDIR/usr/include/m32/* /usr/include/m32/
rm -rf DESTDIR
