Rust low-level bindings for GMP and MPFR
gmp-mpfr-sys crate provides Rust low-level bindings for the
GNU Multiple Precision Arithmetic Library (GMP)
and the GNU MPFR Library, a library for
multiple-precision floating-point computations. The source of the two
libraries is included in the package.
Just like GMP and MPFR, this crate is free software: you can redistribute it and/or modify it under the terms of either
- the GNU Lesser General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version, or

Building on GNU/Linux
To build on GNU/Linux, simply make sure you have
make installed on your system. For example on Fedora:
# sudo dnf install diffutils gcc make
Building on macOS
To build on macOS, you need the command-line developer tools. An easy
way to install them is to start building the crate using
build. If the tools are not installed yet, a popup should appear
which should help you install them.
Building on Windows
You can build on Windows with the Rust GNU toolchain and an up-to-date MSYS2 installation. To install MSYS2, you can do the following:
Install MSYS2 using the installer.
Launch the MSYS2 MinGW 64-bit terminal from the start menu.
Install the required tools.
$ pacman -S pacman-mirrors $ pacman -S diffutils make mingw-w64-x86_64-gcc
Then, to build a crate with a dependency on this crate:
Launch the MSYS MinGW 64-bit terminal from the start menu.
Change to the crate directory. Note that building the GMP and MPFR libraries in MinGW with absolute paths does not work very well, so relative paths are used. If your crate is inside
.cargodirectory is outside
C:\mingw, this will not work. Please move your crate to the same side of
