Hello folks,

make sure your Wine has proper OpenCL support.
You should see 'opencl.dll' being loaded.

Additionally 'WINEDEBUG=+tid,+seh,+loaddll,+opencl' is your friend.

Surely Windows OpenCL drivers are needed and hence will not work?

No, native Windows libs can't work. Wine provides an OpenCL wrapper.

A nice article how to use OpenCL with MetaTrader programmatically ("OpenCL: The
Bridge to Parallel Worlds"):

http://www.mql5.com/en/articles/405

If the 'opencl' debugging channel is enabled you can actually see the API calls
when executing/debugging scriptlets:
