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.
