The smallptgpu example from here ocltoys-linux64-v1.0.zip at
http://code.google.com/p/ocltoys/downloads/list

doesn't work:

Comment 1 Fabian Deutsch 2014-01-11 21:45:30 UTC 
YOu might need to run

$ sed -i "s/^static//" *.cl

to remove the static modifier from the (inclid) cl files.
Comment 2 Fabian Deutsch 2014-01-11 21:45:56 UTC 
This was (after clinfo) the first example which was run on Fedora 20 and mesa 10.
Comment 3 Fabian Deutsch 2014-01-11 21:50:21 UTC 
Does r600 have floating-point support? or might this bug be because of a missing float support?
Comment 4 Jan Vesely 2017-07-28 15:22:06 UTC 
This is an old bug. All ocl-toys examples run OK on my AMD TURKS (DRM 2.49.0 / 4.11.11-300.fc26.x86_64, LLVM 6.0.0).

Please reopen if you still see the issue.
