of course - it's written against 6.10.1. you should download sources
of your GHC version and use example from it. look in
http://www.haskell.org/ghc/dist/stable/dist/old

Thanks for this.  

I noticed some errors in the sample that might help others:  
1) you need to replace "win32" with "Win32" in the given command line 
instruction
2) the Win32 package in this link gives a type error during the "setup build" 
phase (expecting exception and given ioerror?) but you can compile the example 
against the Win32 package in ghc 6.8.3

you should look at Win32 package sources which includes small example
using WinAPI for "hello world" GUI application

but note that Win32 binding is far from complete. if i will start to
write WinAPI GUI app, i may prefer to do GUI part in C and communicate
to Haskell part via FFI

[Haskell-cafe] a minimal Windows program in Haskell?

2008-11-02 Thread Nun Aurbiz 
How do I make a minimal Windows application in Haskell?  I know there are Win 
API bindings in the libraries, and of course the ffi lets you call into and out 
of C, but I have no sense of how to bring it all together.  I can't find any 
samples either.

Is the Haskell code the "main" application and you just ffi into the Win API?  
Or does it ffi into a win_main.c that I write?  Or is the win_main.c the "main" 
application and it calls into Haskell?

Here is what I am talking about by a "minimal Windows application" (written in 
psuedo C code).

#define WIN32_LEAN_AND_MEAN
#include 

LRESULT CALLBACK windowsProcedure(..) {
switch(message) {
case WM_CLOSE:
PostQuitMessage(0);
return 0;
}
return DefWindowProc(..);
}

int APIENTRY WinMain(..){
WNDCLASS window_class;
RegisterClass(&window_class)
window = CreateWindow(..);
ShowWindow(..);

while(true) {
/* do whatever */

while(PeekMessage(..))
if(msg.message ==  WM_QUIT)
return msg.wParam;
else
DispatchMessage(&msg);
}
return 0;
}
