Welcome to the Erlang OpenCL binding To get started you need erlang, preferably R16B or later. 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 ------------------------------ Setup windows build environment c:\src\cl> "c:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd" x64 before starting msys (with inherited env) cl> export PATH="/c/Program Files/erl5.10.1/bin";%PATH% cl> export PATH="/c/tools/git/cmd";%PATH% cl> export OPENCL_DIR="c:\Intel~1\" And build cl> ../rebar/rebar.cmd compile ======= If you want to force build with mingw gcc use: NOCL=true rebar compile
