Sobel OCL test build fails

[dineiar]

Whenever I try to build the Sobel test with a make it throws this error:

In file included from ../../../ff/stencilReduceOCL.hpp:47:0,
                 from ffsobel_pipe+mapOCL.cpp:56:
../../../ff/oclnode.hpp: At global scope:
../../../ff/oclnode.hpp:79:13: error: ‘fftype’ does not name a type; did you mean ‘wctype’?
     virtual fftype getFFType() const   { return OCL_WORKER; }
             ^~~~~~
             wctype

I couldn't find the definition of fftype, where should it be defined?

It also shows this error:

ffsobel_pipe+mapOCL.cpp: In lambda function:
ffsobel_pipe+mapOCL.cpp:270:35: error: ‘EOS’ was not declared in this scope
         return static_cast<Task*>(EOS);

Environment:
Ubuntu 18.04.4
g++ (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0
FastFlow's git commit: 9ba56e7, error also happens in v3.0 (ad4dccf).

I just tested v2.2 (b396caa) and the error is gone.

Thanks for reporting this issue. In FF version 3, both OpenCL and CUDA support (as well as the distributed support) have been left behind, and so almost all tests do not compile or don't work. I need to make an effort to re-align OpenCL and CUDA support as soon as possible. Thanks for your patience.
