OpenCL S3D fails on OS X #6

Closed rothpc closed 12 years ago

Gives the following output:

So this complains about source for ratt10.cl and ratxb.cl, but exp() is a built-in OpenCL math function. Am I missing something here? Confirmed exp presence in 1.0 and 1.1 spec.

I think I know what's going on. A missing CPREC around a constant, so it is treating it as double precision and there isn't a double precision exp(). Give me a few minutes and I'll see if I'm right.

Hmm I see several missing CPREC wrappers, so I will follow up on those after your testing anyway.

rothpc commented 12 years ago

Yes, I think that's what the problem is. Fixing ratt will take a while, the others are already done.

I think all these are now committed.

rothpc commented 12 years ago

Yes, this issue is resolved.
