The MAGICAL analog router.

How to install ?

The following dependencies are required.

• Boost >= version 1.6
• LIMBO Set the env variable LIMBO_DIR or specify cmake -DLIMBO_DIR=<path>
• lemon Set the env variable LEMON_DIR or specify cmake -DLEMON_DIR=<path>
• SparseHash Set the env variable SPARSE_HASH_DIR or specify cmake -DSPARSE\_HASH\_DIR=<path>
• pybind11 Please see the official document for installing the pybind11. Set the env variable PYBIND11_DIR or specify cmake -DPYBIND11_DIR=<path>. To use other Python versions, add cmake flags cmake -DPYTHON_EXECUTABLE=<path>

In the directory of anaroute, run

mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=absolute/path/to/your/installation -DPYTHON_EXECUTABLE=<path> ..
make
make install
cp *.so ~/.local/lib/pythonX.X/site-packages/ (your python version)
