Cross-Compiled Linux From Scratch - Version SYSVINIT-20170702-MIPS64-Multilib

Chapter 6. Constructing a Temporary System

6.3. GMP-6.1.2

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

6.3.1. Installation of GMP

As with the Cross-Tools, we will compile GMP, MPFR, MPC, and ISL so that GCC can use them, though this time we will cross-compile them into /tools.

Prepare GMP for compilation: 

CC_FOR_BUILD=gcc \
./configure \
    --prefix=/tools \
    --build=${CLFS_HOST} \
    --host=${CLFS_TARGET} \
    --libdir=/tools/lib64 \
    --enable-cxx

The meaning of the new configure option:

CC_FOR_BUILD=gcc

Tells configure to use the host's gcc instead of our cross-compiler to build native tools it needs while compiling.

Compile the package: 

make

Install the package: 

make install

Details on this package are located in Section 10.14.2, “Contents of GMP.”
