I was recently trying to run a piece of code on a gpu that works fine on my cpu when I received the following error:

Buid Log:
Internal error: Link failed.
Make sure the system setup is correct.

Has anyone else received this error or know where it comes from?

Thanks!

I was able to fix this error.  Turns out to be a problem with << operators.

Please post your kernel code which shows Link failed error so that we can fix in upcoming releases.

int bits = ((nextT[0] < nextT[1]) << 2) + ((nextT[0] < nextT[2]) << 1) + (nextT[1] < nextT[2]);

int cmpToAxis[] = {2, 1, 2, 1, 2, 2, 0, 0};

int stepAxis = cmpToAxis[bits];

this is the code that was causing the problems.  I could have a problem with missing something from the OpenCL spec though.

what is the datatype of nextT?

twiig,

I tried running your code(with nextT as uint*) and did not get any issues.

Which datatype is your nextT?
