coraxlib (COre RAXml LIBrary) encapsulates common routines used by likelihood-based
phylogenetic software such as raxml-ng.
It will eventually supersede both libpll-2
Please read the wiki for more information.
Please make sure you have CMake 3.0.2 or later installed on your system.
Then, use following commands to clone and build
git clone https://codeberg.org/Exelixis-Lab/coraxlib.git cd coraxlib mkdir -p build && cd build cmake .. make
If you want to install
coraxlib system-wide, please run:
sudo make install
The library will be installed on the operating system's standard paths. For
some GNU/Linux distributions it might be necessary to add that standard path
/etc/ld.so.conf and run

Registering and running tests
We use CTest for manageing our automated tests. You can thus use a standard CMake workflow:
cmake -B build cmake --build build -j pushd build && ctest; popd
We use Googletest for our unit tests.
To register a new unit-test, create a file in
test/unit/src and add the following line to
corax_register_test(test_my_awesome_new_test FILES src/my_awesome_new_test.cpp) # or corax_register_test(test_with_custom_defines FILES src/with_custom_defines.cpp DEFINES SAMPLE_DEFINE=1 ANOTHER_DEFINE=2)
On Linear Algebra Libraries
The situation with linear algebra libraries is complicated. To build coraxlib in with non-reversible models enabled, the following needs to be provided in some way:
- CBLAS (a C interface to BLAS)
- LAPACKE (a C interface to LAPACK)
Both of these packages normally depend on BLAS and LAPACK, respectively. Therefore, you will probably need to install all four.
We recommend that users install OpenBLAS. Depending on the package manager, this will provide the interface to all of the above. If this is not the case, then try installing CBLAS and LAPACKE, as these are the final targets required. However, not all BLAS implementations are the same, strictly speaking. If you get linker errors, it is probably due to the installed BLAS implementation not providing "extra" functions, which are present in OpenBLAS.
