Installation of libcint

Libcint needs to be installed separately, it is distributed under the BSD-2-Clause and available at GitHub.

First, download the source,

$ git clone http://github.com/sunqm/libcint.git

then build build it

$ cd libcint
$ mkdir build; cd build
$ cmake -DCMAKE_INSTALL_PREFIX:PATH=$HOME/libcint/ ..
$ make install

and finally, add the library to the PATH environment variable by adding:

$ export PATH=$PATH:$HOME/libcint

to your ~/.bashrc.

Hint

There is also an X86 optimized version of libcint, which can be installed in a similar way: https://github.com/sunqm/qcint
