Installation

Requirements

cmake is required for building the library. Gromacs 2016+ is required, since the library links to some of its functions. xdrfile is required.

Installing

A typical install consists of downloading the most recent tarball and extracting it. Enter the source directory. Then do:

mkdir build
cd build
cmake ..
make
make install

You may need superuser privileges for the last step, or you may need to specify a different installation directory (like your home folder) with the cmake option -DCMAKE_INSTALL_PREFIX above.

Alternatively if you are running Arch you can install it from the AUR.

Classes for use with AVX Instructions

Some classes are provided for use with SIMD intrinsics, specifically the AVX set. To compile with these classes available, add -DAVX=ON to your cmake call when installing. This is experimental, since tests have not been implemented for these classes yet.

Unfortunately I don’t have time to cover all instruction sets, so I’m focusing on those most useful to myself. If you’re interested in adding more, please file a pull request.

A good example of this in practice, is my test particle insertion code found here. Specifically look at the CalcPE function in Atomtype.cpp.

Turning off banner

By default a banner is printed to stderr every time a Trajectory object is created. If this annoys you, use the cmake flag -DBANNER=OFF to turn it off.

Location

Header files will be installed within a folder named gmxcpp.

Testing the build

To test your build you can run make test in the build directory (see above).

Automated tests were performed via Travis when new commits were pushed, but a newer compiler is required than available. Specifically, “<random>” is used in some utilities.

Documentation

If you want to have a local copy of the documentation, do make docs in the build directory. The html files will be placed in docs/html in your build directory. sphinx, breathe, and doxygen are required to build the documentation. Install doxygen with your package manager (e.g., sudo apt-get install doxygen). Install sphinx and breathe with:

sudo pip install sphinx
sudo pip install breathe

Additionally the source code is well-documented, containing more detail than the generated documentation.
