Contributions to this project are accepted, but Contributors have to sign an Assignment Agreement, please follow the instructions in contributor-agreement.pdf. This is needed so upstreaming code to projects that require copyright assignment is possible. Further contribution requirements are documented in README.contributors of the appropriate subdirectory.
Regular quarterly releases are tagged as vYY.MM, the latest release is v24.05.
Source code layout:
build/ - build directory (created by make). math/ - math subproject sources. math/include/ - math library public headers. math/test/ - math test and benchmark related sources. math/tools/ - tools used for designing the algorithms. networking/ - networking subproject sources. networking/include/ - networking library public headers. networking/test/ - networking test and benchmark related sources. string/ - string routines subproject sources. string/include/ - string library public headers. string/test/ - string test and benchmark related sources. pl/... - separately maintained performance library code.
The steps to build the target libraries and run the tests:
cp config.mk.dist config.mk
make make check
Or building outside of the source directory:
ln -s path/to/src/Makefile Makefile cp path/to/src/config.mk.dist config.mk echo 'srcdir = path/to/src' >> config.mk
make make check
Or building and testing the math subproject only:
make all-math make check-math
The test system requires libmpfr and libmpc. For example on debian linux they can be installed as:
sudo apt-get install libmpfr-dev libmpc-dev
For cross build, CROSS_COMPILE should be set in config.mk and EMULATOR should be set for cross testing (e.g. using qemu-user or remote access to a target machine), see the examples in config.mk.dist.
