Hi,

I'm switching from Visual Studio to QTCreator to develop my OpenCL application and I would like to do some "printf" from my kernel.

The problem is that it doesn't work !

I have try to call AllocConsole, to put my app in console mode... nothing !!!!

Do you have an idea ?

Which version of SDK are you using? According to AMD ATI Stream SDK 2.2 supports printf in kernel, search printf in this page

Try also this page

Thx,

I'm using SDK 2.2 and I use printf since a lof of time !

I have do openCL with C#, MSVC and now QT. With C# I have call 'AllocConsole' and everything was fine. But, here with QT I can't print anything !

Also, what is strange is that during kernel compilation several console are appearing and disappearing !!! But my created console is still empty !

Thx

viewon01,

AFAIK, QT absorbs the standard output. You might get more help at QTforums.
