6.14.5. Contents of GMP
Installed Libraries:
libgmp.{a,so} and libgmpxx.{a,so}
Installed directory:
/usr/share/doc/gmp-6.0.0a
6.14. GMP-6.0.0a
The GMP package contains math libraries. These have useful functions for arbitrary precision arithmetic.
Approximate build time:
1.3 SBU
Required disk space:
65 MB
6.14.1. Installation of GMP
6.14.2. 32-bit Installation
Prepare GMP for 32-bit compilation:
ABI=32 ./configure --prefix=/usr --enable-cxx \ --libdir=/usr/lib32 \ CC="gcc -m32" CXX="g++ -m32"
The meaning of the new configure options:
-
ABI=32 -
Tells the configure script that we are building a 32-bit version of GMP.
-
--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 188 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
Create the 32-bit header file:
mv -v /usr/include/gmp{,-32}.h
Clean up the build directory before moving on to the next platform:
make distclean
6.14.3. x32 ABI Installation
Prepare GMP for x32 ABI compilation:
ABI=x32 ./configure --prefix=/usr --enable-cxx \ --libdir=/usr/libx32 \ CC="gcc -mx32" CXX="g++ -mx32"
The meaning of the new configure options:
-
ABI=x32 -
Tells the configure script that we are building an x32 ABI version of GMP.
-
--enable-cxx -
This parameter enables C++ support
Compile the package:
make

make distclean
6.14.4. 64-bit Installation
Prepare GMP for 64-bit compilation:
./configure --prefix=/usr \
--enable-cxx \
--docdir=/usr/share/doc/gmp-6.0.0a
The meaning of the new configure options:
-
--enable-cxx -
This parameter enables C++ support
-
--docdir=/usr/share/doc/gmp-6.0.0a -
This variable specifies the correct place for the documentation.
Compile the package and generate the HTML documentation:
make make html

make check 2>&1 | tee gmp-check-log
Ensure that all 188 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 and its documentation:
make install make install-html
Create the 64-bit header file:
mv -v /usr/include/gmp{,-64}.h
Finally, create a stub header in the place of the originals:
cat > /usr/include/gmp.h << "EOF"
/* gmp.h - Stub Header */
