OPENCL error: couldn't get number of OpenCl devices. Device not found

[thesnakeguy]

Hi,

I installed NGM using (mini)conda on ubuntu for windows. I have a i5-5300U (2,3GHz). Everything goes well until [OPENCL] Build status failed: Program build failure is reported (-11). The CPU has 4 cores and -t is set to 4 (I also get the error when setting it lower). What can I do to solve this problem?

Kind regards

Hi,
I had the same problem. I was given the advice to add the option --affine and this solved the problem for me.
Note that it slows down the whole mapping process. I was told that this is rather a hack than a solution to the underlying problem.
The problem with this error message is that OpenCL (a software library to increase mapping speed) is not compatible with all systems. With the option --affine you deactivate OpenCL and circumvent the problem.

Kind regards
