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 ...


OpenCL kernel build output:

"C:\Program Files\Blender Foundation\Blender\2.78\scripts\addons\cycles\kernel\kernels/opencl\../../kernel_projection.h", line 238: error:

          expression must have pointer-to-struct-or-union type

                float altitude = fabsf(safe_asinf(D->z));



1 error detected in the compilation of "C:\Users\s0uLz\AppData\Local\Temp\".

Frontend phase failed compilation.



OpenCL build failed: errors in console


read exr tmp file: C:\Users\s0uLz\AppData\Local\Temp\blender_a00852\BMW1M-MikePan.blend_Scene_RenderLayer.exr

Error: OpenCL build failed: errors in console



Help with this problem would be much appreciated!


Kind Regards
