A very similar error here as well on a new computer with gentoo linux and a 9500gt.

Same here, using an Amazon EC2 GPU Cluster instance (Tesla M2050):

Any ideas?

I came across this issue and decided to take a look at it.

The main problem above is pyOpenCL not exporting the info class variables; see here and here.

Changing line 179 in BitcoinMiner.py to:

`````` binaryW.write(self.miner.get_info(cl.program_info.BINARIES)[0]```
should fix the issue.

However, while that is easily remedied, it exposes bigger problems. These problems may be inherent only to my setup, but if you get something similar (or not) please tell me :)

The main big problem is a type incompatibility between pyOpenCL and the boost library providing the bindings to python concerning the pyopencl.Program.build() method.

build's options argument (or more precicely, _build which is called from build) needs to be a string type. However, pyopencl.Program.build converts strings to lists.

I modified line 465 in pyopencl/_init_.py to:
self._prg._build(' '.join(options), devices)
which converts it back into a string.
