System Information
Win7 x64 GTX580 newest driver

Blender Version
Cmake build
Broken: c27a1cf or earlier but after 7ad9ca7 - and up to the newest cdf2dbe
Worked: 7ad9ca7

Short description of error
Because the latest win64 scons build is several days old (and now even vanished) I tried the Cmake builds, but, at least for me, it's not possible to render with gpu even the default scene (and any other) neither with f12 nor in render preview.

Exact steps for others to reproduce the error
I've attached a screenshot from the system console output.

Oh, if I try the factory settings by creating a config folder in the 2.75 folder under the blender.exe then the default scene renders fine. But without this config folder even a simple cube fails to render. Needs the Cmake build its own new userpref.blend ? But no, it worked in 7ad9ca7 ...

I am not seeing the connection to the buildsystem.

Do you have a 1.5 or a 3gb gtx 580 ?
Are you using the experimental or normal kernel ?
Do I understand correctly that it works if you restore the factory settings ?

"Needs the Cmake build its own new userpref.blend ? But no" No there is no change in userpref.blend and yes the cmake and scons build are the same in this regard and use each others settings .

Could you also test and report if the latest official blender ( that one is build with cmake) is broken for you in this regard ?

3GB GTX580.
Feature set: supported.
Yes, if I create a "config" folder in the "2.75" folder under the installation folder (with the blender.exe) then it works fine.

I just tested 61e4800 and unfortunately the same CUDA error happens.

...
I just tried another machine, winx64 GTX580 3GB too, and the same error happens ...

Btw, what's the meaning of "connection to the buildsystem" ?

A new finding:
I always use the zip installations/extractions.
So, I have a Blender Scons folder and another Blender Cmake folder.
If the original Blender Scons folder is present the Cmake shows the described error.
But if I rename or delete the Blender Scons folder all seems to be fine with Blender Cmake, even with my own userpref and startup file !

Hope this could be a help !?

OK, I don't know anymore if this is realy a bug or my fault !?
Nevertheless the reason for the described behaviour is the path in the userpref for the scripts under the Filetab. In case I use the same userpref, and so the same Scriptspath, the "error" happens.
So the solution, at least for me, is simply to ensure each installation has its own path to its own Scriptsfolder.
Or make the Scriptspath relative.

Thank you !

If you're trying to re-use same scripts folder for different blender version you might really easy to run into issues like CUDA kernel being compiled from much older sources than newer build expects it to be.
