[wxhaskell-devel] how to get rid of command box when launching wxhaskell apps on windows

[john l. <jv...@ho...>]

For those interested (you should consider adding this to the wiki), if you would like your wxApp to launch
under windows like any standard windows app, without the command console (prompt) window also appearing
this can be achieved with ghc (in effect you need to instruct the linker to use the WinMain entry point) this can be done by passing -mwindows to gcc (used in the ghc link phase) as follows ...


>ghc -o HelloWorld.o -fglasgow-exts -c HelloWorld.hs
>ghc -optl-mwindows -o HelloWorld.exe HelloWorld.o -package wxcore

NB: you can do the above in one step as well.

now double click HelloWorld.exe and it will launch like a standard windows app (no DOS box).

to work HelloWorld must contain a Main module, will also work with ghc -main-is option
