libprofit is currently hosted in GitHub. To get a copy you can clone the repository:

Compiling

libprofit depends on:

Both dependencies satisfy the same requirements, so they are mutually exclusive, but at least one of them is necessary. If both are present GSL takes precedence.

Optional requirements are:

libprofit’s compilation system is based on cmake. cmake will check that you have a proper compiler (anything supporting some basic C++11 should do), and scan the system for all required dependencies.

To compile libprofit run (assuming you are inside the libprofit directory already):

$> mkdir build
$> cd build
$> cmake ..
$> make
$> # optionally for system-wide installation: sudo make install

With cmake you can also specify additional compilation flags. For example, if you want to generate the fastest possible code you can try this:

$> cmake .. -DCMAKE_CXX_FLAGS="-O3 -march=native"

You can also specify a different installation directory like this:

$> cmake .. -DCMAKE_INSTALL_PREFIX=~/my/installation/directory

Other cmake options that can be given in the command-line include:

  • LIBPROFIT_USE_R: prefer R libraries over GSL libraries

  • LIBPROFIT_TEST: enable compilation of unit tests

  • LIBPROFIT_DEBUG: enable debugging-related code

  • LIBPROFIT_NO_OPENCL: disable OpenCL support

  • LIBPROFIT_NO_OPENMP: disable OpenMP support

  • LIBPROFIT_NO_FFTW: disable FFTW support

  • LIBPROFIT_NO_SIMD: disable SIMD extensions usage

Please refer to the cmake documentation for further options.
