Starting with Cloo 0.9 the Clootils editor/OpenCL C syntax checker will be discontinued. This very simple editor was conceived in a time when no such tools existed and the only way to test a kernel was to compile a whole OpenCL program. However, the goals of this project never included a full blown OpenCL C editor. And so, with time, this little tool has fallen behind.
You are strongly encouraged to take advantage of the better alternatives that have emerged. Both AMD and Intel now provide such tools for free.
The Clootils tests will remain available.
