Hello Andrew Plenty compile on Windows: Some OpenVG, OpenGL[1] (still? - I'm a bit behind the times) only compile with MinGW. Others are fine with Cygwin provided you have the dev packages installed (readline, pcre-light...). Yet others - no chance... If you can get the raw C library to work in either Cygwin or MinGW, you should have a good chance. The only sound software I've had working on Cygwin has been ChucK though I haven't tried many - ChucK uses RtAudio to talk to the soundcard which probably isn't easy to write a binding for as its C++. I had ChucK working two years ago, maybe things have improved in the Cygwin world regarding sound since then and other systems now work. http://www.music.mcgill.ca/~gary/rtaudio/ Best wishes Stephen [1] OpenGL worked fine when it was bundled with GHC, when it got unbundled things seemed to go amiss, plus it seemed to be the thing to use freeglut - hence the complicated instructions here: http://netsuperbrain.com/blog/posts/freeglut-windows-hopengl-hglut/ ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I'm by no means an expert here, but isn't it usual for C libraries on Windows to be supplied as a compiled DLL and a header file for using it? I don't quite understand why you need a C compiler. The thing is, all the bindings on Hackage (or at least something most likely above 95%) are to Unix C libraries so you need a C compiler and a Unix emulator to use them. I do have have some sympathy with your point though - it is possible to get things to compile once you have Cygwin, but deployment on any other machine Windows thereafter is 'challenging' to say the least. Apparently there is some talk of removing OpenGL from the Haskell Platform.

Re: [Haskell-cafe] Low Level Audio - Writing bytes to the sound card?
You'll have to install the portaudio C libraries and header files before continuing. I never actually tested the package on XP, if you get it to work, I'd love to hear your experience. /jve On Fri, Dec 4, 2009 at 2:20 PM, M Xyz functionallyharmoni...@yahoo.comwrote: Hi, portaudio is my embarrassing fault, but it does work most of the time.

Re: [Haskell-cafe] Low Level Audio - Writing bytes to the sound card?
if you get it to work As a spoiled Java programmer, this new role as pioneer is a bit intimidating, but I will give it a shot. :) I downloaded the portaudio v19 source and I'm attempting to build it. Apparently I have to register my Visual Studio Express with Microsoft. Deeper down the rabbit hole... (Interesting aside, on the registration form under What programming language topics are you interested in? neither F# or Haskell are listed) I wish there was a multimedia standard library for beginners like me. Writing audio to the speakers shouldn't be such a journey. You'll have to install the portaudio C libraries and header files before continuing.

Writing audio to the speakers shouldn't be such a journey. Hi, Did you look at synthesizer ? There is a short introductory file [1]. Be sure to look at the source (there is a link next to each function definition). Outputting list of values is easy, for instance Play.monoToInt16 (44100::Double) (map sin [0::Double,0.1..]) It uses SoX [2], which should be installed.

Did you look at synthesizer ? There is a short introductory file [1]. Cheers, Thu [1] http://hackage.haskell.org/packages/archive/synthesizer-core/0.2.1/doc/html/Synthesizer-Plain-Tutorial.html Thanks for the tutorial link. As I'm new to Haskell, these 2 lines got me thinking: Using plain lists is not very fast and Getting real-time performance is mostly an issue of the right signal data structure. What do you use as an efficient byte buffer in a value-oriented language? The array tutorial says Obviously, a naive implementation of such an array semantics would be intolerably inefficient, either requiring a new copy of an array for each incremental redefinition, or taking linear time for array lookup; thus, serious attempts at using this approach employ sophisticated static analysis and clever run-time devices to avoid excessive copying. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
