[Geany] Help with custom compiler

[Laszlo Nagy]

   Hello,

I'm developing a new language, and I would like Geany to handle it. It 
has a compiler which is a pyhon program. I could use this custom build 
command under linux:


python /whatever_path/compiler.py "%f"

and it works. However, under windows this custom build command:

C:\Python27\python.exe c:\whatever_path\compiler.py "%f"

does not work. When I press F8 then Geany starts python.exe (I can see 
it from the task manager). Then it takes a long time before it responds, 
telling that the compilation failed. If I start the very same command 
line in a terminal (cmd.exe) then it runs within 0.1 sec.

What can be the problem?

My other question is about interpreting the output of my compiler - but 
first I would like to be able to use it under Windows.

Thanks,

    Laszlo
