6.3. GMP-6.0.0

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, ISL, and CLooG 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} \

The meaning of the new configure option:


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

Compile the package:


Install the package:

make install

Details on this package are located in Section 10.10.2, “Contents of GMP.”
