Hello,
Does anyone know how I can launch a batch file from Ocaml without pop up
windows.
Thanks
Fady

"windows" in its name?</troll>

I guess the "cmd.exe" one since Sys.command and Unix.system use the
same underlying function: system(3).
As far as I remember, Unix.create_process will not pop any additional(*) window.
(*) Of course, there's no magic here: if the process itself opens a
console window, you will always get one.
Linking with "gcc -mwindows" or "ld --subsystem windows" (not sure
about the syntax for ld) would solve it. If you can't link again, you
can still modify the binary with a tool or by hand since it's a single
bit (maybe two) in the PE header.
Hope this helps,
Adrien Nader

Hi Fady,
Just launch cmd.exe with the right parameters "/C your_script.bat".
Ideally the path to cmd.exe is stored in the environment variable
"ComSpec". You can also specify read/write/error pipes like for other
usual applications.
Cheers,
