Regular quarterly releases are tagged as vYY.MM, the latest release is v20.11.

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.

The steps to build the target libraries and run the tests:

cp config.mk.dist config.mk

edit config.mk if necessary ...

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

further edits to 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.
