{{Package-Introduction|According to their site, "GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers. There is no practical limit to the precision except the ones implied by the available memory in the machine GMP runs on. GMP has a rich set of functions, and the functions have a regular interface. The main target applications for GMP are cryptography applications and research, Internet security applications, algebra systems, computational algebra research, etc.GMP is carefully designed to be as fast as possible, both for small operands and for huge operands. The speed is achieved by using fullwords as the basic arithmetic type, by using fast algorithms, with highly optimized assembly code for the most common inner loops for a lot of CPUs, and by a general emphasis on speed."|http://gmplib.org/}}

Introduction to GMP

Project Homepage: Unknown

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 ${BUILD32}" ./configure --prefix=/usr \
    --host=${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}" ./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}" ./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__ */
EOF
