Compiled OpenGL program has DOS window?
Hi. I'm working in Windows on an OpenGL application. I finally got everything working, doing all of my testing through the interpreter. When I finally compiled and ran the program from an executable for the first time I noticed that before creating my OpenGL window an empty DOS prompt popped up. I think I understand why the computer would want to do that, but I don't know how to make it stop. I've done some OpenGL in C++ and I remember having a similar problem. If I remember correctly the problem was fixed with a compiler flag. I'm using GHC and I looked through their compiler flags, but I didn't find anything that looked like it would deal with this. Anyone have any ideas? -Eitan
I vaguely recall that there is a way to avoid this if you don't import
any terminal functions or something similar. I don't remember the
specifics though.
Sorry I couldn't be of more help!

You can do this with the flag -optl-mwindows; this passes the flag -mwindows to the linker. Because this is a linker option, you cannot find it in the GHC documentation. This solution also works for other GUIs, like wxHaskell. Regards, Henk-Jan van Tuyl -- http://Van.Tuyl.eu/ http://members.chello.nl/hjgtuyl/tourdemonad.html --

it may be added to some GHC FAQ though -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
