Hello, this is Sean the creater of CLyther, please post any comments here.

Anyway to build for windows?

[sean]

Sorry, there is no stable testing done on windows.
I think that there error is originating from the python binding I wrote. I suspect that it is a minor error.

Any insights would be greatly appreciated.

Thank you

I managed to get it compiled on Windows XP 32-bit, using MSVC-9, Python 2.6 and ATI Stream 2.0, however I had to re-order many variable declarations to make them comply with C89 style (in stead of your C99-style).
However, after successful compilation, I ran the emulation_example.py which fails with the following error:
(is this due to invalid_platform ?)

Traceback (most recent call last):
  File "C:\clyther-0.1-beta\examples\emulation_example.py", line 34, in <module>
    clyther.init( 'EMULATE' )
  File "c:\python26\lib\site-packages\clyther-0.1_beta-py2.6-win32.egg\clyther\static.py", line 92, in init
    _cl_static = StaticOpenCL.getInstance( type ,profile=profile )
  File "c:\python26\lib\site-packages\clyther-0.1_beta-py2.6-win32.egg\clyther\static.py", line 53, in getInstance
    cls.instance = StaticOpenCL( type, profile=profile)
  File "c:\python26\lib\site-packages\clyther-0.1_beta-py2.6-win32.egg\clyther\static.py", line 37, in __init__
    devices = cl.get_devices( type )
Exception: ('OpenCL: Unknown OpenCL error -32', -32)

[sean]

Thank you very much. Could you send me a patch?

Please let me know what svn revision you are using. I may have already fixed this latest bug.

[tvdp]

The patch for opencl_wrapper.c as downloaded from svn trunk now works on win32 platform, it now compiles using MSVC
The patch for setup.py  is only adding a line for building/installing using ATI Stream SDK, for NVIDIA another line is needed as some other user pointed out here.
I'm still having trouble with the __init__ function in static.py, I can only get it to work by adding/modifying some lines:

        platform = cl.get_platforms()   
        devices = platform[0].get_devices( type )
        self.device = devices[0]            
        self.context = cl.Context( devices[0] )

I suspect this is due to me using the newest ATI Stream SDK 2.01 which has something changed from the previous beta,
as specifically documented here:
http://developer.amd.com/support/KnowledgeBase/Lists/KnowledgeBase/DispForm.aspx?ID=71

But since I'm not a real coder myself, I'll leave it to someone else to come up with a patch for this …

I can't build using: python setup.py build
win7x64, clyther-0.1-beta.tar.gz, MSVS2008, ati-stream-sdk-v2.01-vista-win7-64, python 2.6.5
Also, setuptools py was required somehow, and I had to copy the CL folder of headers from ATI into MSVS's include folder to be found.

Mostly syntax erros similar to aperske. Full details:

running build_py
running build_ext

Btw, the python 2.6.5 is 32bit. I think MSVS is both 32/64.

[sean]

Could you please check if the error ocurrs with the latest build clyther-0.1-beta-3.tar.gz we fixed some outstanding issues with the windows build.

Thanks

[Nobody/Anonymous]

How alive is this project?  I successfully built clyther-0.1-beta-3 for python 2.7 on win7 with CUDA.

[Nobody/Anonymous]

Yes. Sorry about the lack of activity. I expect to have a new version out in a few weeks.

[Joe Kilner]

Just to repeat the previous question, how active is this project? It looks really good, but I don't see many recent updates or discussions…

[sean]

Hello, as you can tell from my delayed reply, that there is not much development at the moment. However I am fixing all reported bugs.

[sean]

In case anyone is still watching this list.  CLyther has move to GitHub. There is a new 0.2-beta release.
