Contributions 6to this project are accepted, but Contributors have to sign an 7Assignment Agreement, please follow the instructions in 8contributor-agreement.pdf. This is needed so upstreaming code 9to projects that require copyright assignment is possible. 10 11Regular quarterly releases are tagged as vYY.MM (e.g. v19.11). 12 13Source code layout: 14 15build/ - build directory (created by make). 16math/ - math subproject sources. 17math/include/ - math library public headers. 18math/test/ - math test and benchmark related sources. 19math/tools/ - tools used for designing the algorithms. 20string/ - string routines subproject sources. 21string/include/ - string library public headers. 22string/test/ - string test and benchmark related sources. 23 24The steps to build the target libraries and run the tests: 25 26cp config.mk.dist config.mk 27# edit config.mk if necessary ... 28make 29make check 30 31Or building outside of the source directory: 32 33ln -s path/to/src/Makefile Makefile 34cp path/to/src/config.mk.dist config.mk 35echo 'srcdir = path/to/src' >> config.mk 36# further edits to config.mk 37make 38make check 39 40Or building and testing the math subproject only: 41 42make all-math 43make check-math 44 45The test system requires libmpfr and libmpc. 46For example on debian linux they can be installed as: 47 48sudo apt-get install libmpfr-dev libmpc-dev 49 50For cross build, CROSS_COMPILE should be set in config.mk and EMULATOR 51should be set for cross testing (e.g. using qemu-user or remote access 52to a target machine), see the examples in config.mk.dist. 53
