Building CN24

Dependencies

CN24 uses the CMake cross-platform build system. You need at least version 2.8 to generate the build files. The following compilers are supported for building CN24:

• GCC >= 4.8
• Clang >= 3.5
• Visual Studio >= 2013

Older versions will probably work as long as they support the C++11 features used by CN24. All other dependencies are optional. Optional dependencies include:

• libjpeg and libpng to read .jpg and .png files
• Intel MKL, AMD ACML or ATLAS for faster calculations
• OpenCL and clBLAS for GPU acceleration (either both or none!)
• GTK+ 3 for GUI utilities

Installing clBLAS

Consider installing clBLAS for high performance training and prediction. Installation is simple:

• Linux: Install boost using your distribution's package manager, then run the included ci/install_clblas.sh script.
• Mac OS X: Install clBLAS using the homebrew package manager: brew install clblas
• Windows: Install a binary release from the clBLAS GitHub releases page.

Note that for all systems except for Mac OS X you have to install the correct OpenCL libraries for your GPU beforehand.

Building CN24

First, make sure you have all the required dependencies. Then, clone the CN24 repository:

git clone https://github.com/cvjena/cn24.git

Create a build directory, switch to it and run CMake:

mkdir build
cd build
cmake path/to/cn24

Take a moment and run ccmake (or cmake-gui) to see all the available build options. We highly recommend selecting at least the libpng and/or libjpeg options:

ccmake .

Run your preferred build tool, for example:

make

That's it, you're done!
