    take review comments into account * protect GCC-specific stuff * use `list(APPEND...)` * use CMake-style way to choose whether LTO should/can be done or not * only install public header, not all * add correct `install` option for DLL's on Windows * use correct folder for .pc files * check if `uname` exists & add support for FreeBSD Signed-off-by: Steffen Jaeckel <s@jaeckel.eu>

    Summary

    The develop branch contains the in-development version. Stable releases are tagged.

    Documentation is built from the LaTeX file bn.tex. There is also limited documentation in tommath.h. There is also a document, tommath.pdf, which describes the goals of the project and many of the algorithms used.

    The project can be build by using make. Along with the usual make, make clean and make install, there are several other build targets, see the makefile for details. There are also makefiles for certain specific platforms.

    Testing

    Tests are located in demo/ and can be built in two flavors.

    • make test creates a stand-alone test binary that executes several test routines.
    • make mtest_opponent creates a test binary that is intended to be run against mtest. mtest can be built with make mtest and test execution is done like ./mtest/mtest | ./mtest_opponent. mtest is creating test vectors using an alternative MPI library and test is consuming these vectors to verify correct behavior of ltm

    Building and Installing

    Building is straightforward for GNU Linux only, the section “Building LibTomMath” in the documentation in doc/bn.pdf has the details.

    CMake support

    The project provides support for the CMake build system.

    git clone https://github.com/libtom/libtommath.git
    mkdir -p libtommath/build
    cd libtommath/build
    cmake ..
    make -j$(nproc)

    A shared library build can be done by setting -DBUILD_SHARED_LIBS=On when invoking the cmake command.
