Cross-Compiled Linux From Scratch - Version 3.0.0-SYSTEMD-MIPS

Chapter 5. Constructing Cross-Compile Tools

5.7. GMP-6.0.0

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

5.7.1. Installation of GMP

This package and the next two - MPFR and MPC - will be installed into /cross-tools because GCC requires them to build.

[Note]

Note

If you are building with a host which has 32-bit user-space with a 64-bit capable CPU, cross-tools GMP will attempt to link with 64-bit libraries. Add the following variable during configure to force GMP's ABI: ./configure ABI=32

Prepare GMP for compilation: 

./configure --prefix=/cross-tools --enable-cxx \
    --disable-static

The meaning of the new configure option:

--enable-cxx

This tells GMP to enable C++ support.

Compile the package: 

make

Install the package: 

make install

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