Regular quarterly releases are tagged as vYY.MM, the latest

release is v21.02.

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.
