I think it's important to distinguish between being a new API and being a faithful binding to an established API. In reality it ends up as a continuum because an exact one to one mapping is not possible between idiomatic C and idiomatic Haskell. If someone is renaming things or changing the API when not strictly necessary then I would say person is making a new API based on the the old API. My desire is to have a binding which is faithful to the C API and then letting people build new abstractions on top of that. > When the mapping between the old and the new naming > conventions are learned, they will benefit from having a more clean > interface for all future times. (No Haskell hacker should have a > problem with a steep learning curve.) I have to disagree here, based largely on my experience with learning other Haskell bindings (for example OpenGL, which I knew from C). If I were to twist your words I could use this to say that we should make Haskell hard to learn. I doubt that's what you meant but it seems dangerously close to me. Probably we have very different goals. You want to make a nice OpenCL-based API for parallel programming and I want a binding that matches the OpenCL api very closely, but not to the point of using Ptr () in many places. > It is somewhat troubling that we now have five different interfaces to > OpenCL (that I know of), and I think we should join efforts and make > one library that is as stable as possible. The five libraries are: I agree that having so many implementations of the binding is odd. I wonder if it's because they cater to different needs. In the case of OpenCLRaw we could reasonably remove it from the list because it's unmaintained and incomplete. And yes, it would be nice to merge efforts.

For now I have bundled the OpenCL header files with my package. That is not the right way either, as the header files can contain some platform specific information, for instance information about the calling conventions, which would be a way to handle the problem above (and the only way possible with c2hs, as far as I know). -- Martin Dybdal ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

The main developer make no reply. * OpenCL, HsOpenCL and hopencl are the packages more suitable tu fuse. I think that the best aproach is to use the OpenCL standard API as it is, and let more libraries that use *opencl* packages decide what high-level API offer. I like the Accelerate approach to show a better API to users. I currently working in the application that need the use of OpenCL. The package that I develop offers all I need for now, so I not upgrading it, only bugs or requested features for users. But in the future I plan for two options: a) change to the *opencl* package that gets mainstream, or b) continue with own OpenCL package because it feels ok. > My own library is available at https://github.com/HIPERFIT/hopencl and > will be released on hackage very soon (next week probably).

I don't think inlining matters in this case. If you distribute a work incorporating GPL code, you must allow the recipient to redistribute it (including all sources) under the GPL. Clearly, GPL code is not suitable when you wish to redistribute it along with proprietary code, but it should be unproblematic for most open source projects. For *L*GPL code, the intention is that it can apply to a library, distributed as a separate unit, and allowing it to be *used* as such, also by proprietary applications. Inlining through static linking may affect this, as it incorporates actual code from the LGPL library in a program that is then distributed as a propietary, binary object. > I understand your point.

If you are happy with BSD3, that license is the one which will make your code most generally useful. The intent behind the GPL family is to make the code useful to those who reciprocate the sentiment, and less useful to those who don't. In practice, it is rare that BSD3 licensed libraries are made proprietary, it is often to everybody's benefit that thinks are maintained in the open. The general sentiment in the Haskell community is a preference for BSD. -k -- If I haven't seen further, it is by standing in the footprints of giants ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

[Haskell-cafe] ANN: OpenCL 1.0.1.3 package
Hello, all. I want to show you the OpenCL package. I have done this using Jeff Heard OpenCLRaw package, but I create a new one due the lack of updates of the former. # Where to get it * Hackage page (http://hackage.haskell.org/package/OpenCL) * Repository (https://github.com/zhensydow/opencl) * Bugs (https://github.com/zhensydow/opencl/issues) * Examples (https://github.com/zhensydow/opencl/tree/master/examples). # Things: * I write it's high-level binding to OpenCL libraries, but only because I added more types to hide most of the alloc/free of the API, and hide the enums using c2hs enums. * The worst problem of the OpenCLRaw is the bad types it use, I learn to fix 32/64 bits issues with c2hs, and test it on linux machines. * Tested on Linux + NVidia only. * Jason Dagit is helping with Windows, OSX testing in own fork, also the call-conv fork in github has changes to work on Windows Please, Consider it's on experimental status but it works, I need lots of feedbacks for detect posible errors, Thanks, ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
