I am trying to render my Images in GPU Computer but after 1 Minute or so this message pops up:

OpenCL build failed: errors in console.

Now whats with that? Anyone experiencing that as well?

Working on: MacBook Pro (Retina, 15-inch, Late 2013) 2.3 GHz Intel Core i7 NVIDIA GeForce GT 750M 2048 MB

    $\begingroup$ As the message says, did you checked the console? $\endgroup$ – Antonio Buch Mar 2 '16 at 18:51
  • $\begingroup$ BTW as far as I can see, your card is compatible with Cycles $\endgroup$ – Antonio Buch Mar 2 '16 at 19:05
  • $\begingroup$ Check that the drivers for your GPU are up to date. Try Re-installing them $\endgroup$ – cegaton Mar 2 '16 at 19:07

    $\begingroup$ What is the error message in the console? $\endgroup$ – cegaton Mar 2 '16 at 19:08
  • $\begingroup$ @SebastianJaeger to access the console please read: blender.org/manual/interface/window_system/… $\endgroup$ – cegaton Mar 2 '16 at 20:37

As I just investigated in https://developer.blender.org/T48842 - if no errors was really produced (despite msg "errors in console. ") try to run blender with "--debug-memory" option - it enables "fully guarded memory allocator" which magically does things.


Nvidia Graphic Cards don't really work with OpenCL on OSX.

You have to install CUDA, restart Blender and chosse in the

User Preferences --> System --> Compute Device --> GPU


Then it should work.
