Welcome to the Erlang OpenCL binding To get started you need erlang, preferably R16B. You also need 'rebar3' and a 'C' compiler, i.e. GCC (or CL.EXE) and a machine with OpenCL installed. To build and test: rebar3 do compile, edoc, ct To build examples: Goto the examples directory and run make. Windows Users: The build look for the OpenCL files in /opt/local/ by default. You can also set the environment variable OPENCL_DIR to point to another location. This is an example of howto set up the building env: I'm assuming you got an mingw environment. Download a development kit from Nvidia, ATI or Intel: e.g. http://software.intel.com/en-us/vcsource/tools/opencl-sdk-2013 cp -R /c/Intel SDK/lib /opt/local/ cp -R /c/Intel SDK/include /opt/local/ Example building 64b from CMD: ------------------------------ Setup windows build environment c:\src\cl> "c:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd" Setup the paths c:\src\cl> set PATH="c:\Program Files\erl5.10.1\bin";%PATH% c:\src\cl> set PATH="c:\tools\git\cmd";%PATH% c:\src\cl> set OPENCL_DIR="c:\Intel~1\" And build c:\src\cl> ..\rebar\rebar.cmd compile ======= If you want to build with mingw gcc use: CC=gcc rebar compile NOTE: That mingw64-gcc can not be linked with MSVC libs, see http://sourceforge.net/apps/trac/mingw-w64/wiki/Answer%2064%20bit%20MSVC-generated%20x64%20.lib Follow the steps there to make a libOpenCL.dll.a and it should work. NOTE: OpenCL with ATI drivers for CPU usage don't work when erlang is started within a mingw shell but does if you start it from a Windows CMD.exe shell. (This may depend on the AMD driver version)
