cudaSafeCall() Runtime API error in file <xxx>, line xx: unknown error. cuda sdk openGL apps s

I don’t know what happened, it could either be due to some updates on my system (but note that I didn’t update the kernel or anything like that) or the “make debug=1” in the sdk.

The problem is that cuda openGL stopped working.

Any ideas on how to fix my problem?

Thanks

This problems is because you haven’t linked the libGL.so properly.

I recommend you to link it, using this :

sudo ln -s /usr/lib/libGL.so.260.19.44 /usr/lib/libGL.so

Notice that this command may change due the Linux flavor that u use and

the libGL versión that had been installed.

If you have more questions about it you can consult this little guide:
