linux

git
cmake
g++ (should support c++0x; eg 4.4 or better)
An OpenCL-compatible driver installed, and OpenCL-compatible GPU
- tested using beignet, which provides OpenCL 1.2; and on CUDA 6.5 driver
opencl-headers
make

git clone --recursive https://github.com/hughperkins/DeepCL.git
cd DeepCL
mkdir build
cd build
cmake ..
make

Note:

be sure to add --recursive when you clone, else when you build it will complain about OpenCLHelper missing (or clew missing)
- if you do forget, you can experiment with running git submodule init --recursive, and then git submodule update --recursive
you might need to play around with commands such as git submodule update --recursive occasionally, to pull down new OpenCLHelper updates

Windows

git
cmake
Visual Studio (current 'standard' build system is: Visual Studio 2010 Express, but should also work on Visual Studio 2008 for Python 2.7, and Visual Studio Express 2013)
An OpenCL-compatible driver installed, and OpenCL-compatible GPU

in git, do git clone --recursive https://github.com/hughperkins/DeepCL.git
create a subdirectory build in the git cloned DeepCL directory
open cmake, point at the DeepCL directory, and set to build in the build subdirectory
- configure then generate
open visual studio, and load any of the projects in the build directory
- change release type to Release
- choose build from the build menu
after building, you will need to copy the *.cl files by hand, from the cl directory

You will need:

libDeepCL.so (or DeepCL.dll)
*.cl files *.cl files no longer needed at runtime :-) They're packaged inside the dll/so now.

~~The *.cl files should be in the current working directory at the time that you call into any DeepCL methods.~~
