Re: [Gegl-developer] Building opencl branch

For now, I've been using the gegl op tool in gimp to test gegl
operations with OpenCL.
But it shouldn't be hard to create a simple filter using the gegl API
and test performance.

If you want to enable OpenCL, just set the GEGL_USE_OPENCL env variable [1].

Also, if you build gegl with --enable-debug, you can set
GEGL_DEBUG=opencl and get some messages about what's going on [2].
Take care that these messages change execution time.

Ok, I see, that opencl branch is outdated, I successfully compiled and
installed version 0.2 from master.

But there is a question: do you have some code examples/tests I should
run to give you information about bugs/speed comparison? I did not found
any opencl tests in master.

I have this config right now:
- Mageia 2 Operating System
- gegl 0.2 from git
- GIMP 2.8
- Intel Pentium 4 CPU 3.0 GHz
- 8 Gb RAM pc-10660
- Nvidia GeForce GT430 GPU

So, it is already integrated in master, you can just ignore the
branch. Victor

I clone a repo with gegl and build it. But when I ckeckout to branch
opencl-ops I get segfault on building stage! Is it normal?

I compiled master, but there is no some OpenCL tests...
