Introduction to GMP

GMP is a library for arithmetic on arbitrary precision integers, rational numbers, and floating-point numbers.

Project Homepage: http://gmplib.org/

Dependencies

Non-Multilib

Compile the package:

./configure --prefix=/usr --enable-cxx \
    --enable-mpbsd &&
make

Install the package

make install

Multilib

32Bit

Compile the package:

CC="gcc ${BUILD32}" CXX="g++ ${BUILD32}" ./configure --prefix=/usr \
    --host=${CLFS_TARGET32} --enable-cxx \
    --enable-mpbsd &&
make

Install the package

make install &&
mv -v /usr/include/gmp{,-32}.h

Command Explanations

--enable-cxx: Enables C++ support.

--enable-mpbsd: Configures make to build the Berkeley MP compatibility library.

N32

Compile the package:

CC="gcc ${BUILDN32}" CXX="g++ ${BUILDN32}" ./configure --prefix=/usr \
    --libdir=/usr/lib32 --enable-cxx \
    --enable-mpbsd &&
make

Install the package

make install &&
mv -v /usr/include/gmp{,-n32}.h

64Bit

Compile the package:

CC="gcc ${BUILD64}" CXX="g++ ${BUILD64}" ./configure --prefix=/usr \
    --libdir=/usr/lib64 --enable-cxx \
    --enable-mpbsd &&
make

Install the package

make install &&
mv -v /usr/include/gmp{,-64}.h

Creating a Stub Header (Multilib Only)

Creating a Generic Stub Header

cat > /usr/include/gmp.h << "EOF"
/* gmp.h - Stub Header  */
#ifndef __STUB__GMP_H__
#define __STUB__GMP_H__

#if defined(__x86_64__) || \
    defined(__sparc64__) || \
    defined(__arch64__) || \
    defined(__powerpc64__) || \
    defined (__s390x__)
# include "gmp-64.h"
#else
# include "gmp-32.h"
#endif

#endif /* __STUB__GMP_H__ */
EOF

Creating a Stub Header For Mips

cat > /usr/include/gmp.h << "EOF"
/* gmp.h - Stub Header  */
#ifndef __STUB__GMP_H__
#define __STUB__GMP_H__

#include <sgidefs.h>

#if (_MIPS_SIM == _ABIO32)
# include "gmp-32.h"
#elif (_MIPS_SIM == _ABIN32)
# include "gmp-n32.h"
#elif (_MIPS_SIM == _ABI64)
# include "gmp-64.h"
#endif

#endif /* __STUB__GMP_H__ */
