Hello dear Sirs at AMD,
for a very long time i have been trying to get cycles rendering under blender to work with my 5870 graphics card. I´am currently using Windows 10 Pro, with the last official Catalyst 15.7.1 version. I have a AMD Phenom2 1055T 6core CPU, 8GB or RAM and a M4A89GTD-pro/usb3 Motherboard and i use the latest Blender version 2.78a, just for info. I have put days of time into trying to figuring out whats going on. I have tried many different Blender versions, without success.
When i try to render under cycles with my GPU, for example a basic Cube with 1 light source or the famous "BMW1M-MikePan" file, this is what my Console tells me after 3 seconds:
Device init success
Compiling base_kernel OpenCL kernel ...

Help with this problem would be much appreciated!
