All, I'm stuck with a Pyinstaller problem (Windows 7, latest pyinstaller from git, Python 2.7). I'd like to create an application without a console window, so I pass --noconsole to pyinstaller. However, I also call some external programs from my application, which is causing problems:
1. If I use subprocess.call and friends, I get the exception OSError exception "[Error 6] the handle is invalid." This is because a noconsole app has no stdin/stdout/stderr; by default, subprocess tries to pass these on to the child process, which fails. 2. If I use subprocess.call with stdin=PIPE, stdout=PIPE, stderr=PIPE (which opens a pipe between the child process and my parent Python process), everything works, but I get a command window that appears briefly on the screen. Because I call this child process a lot, I see a lot of distracting consoles opening and closing. 3. Trying op.spawnl produces identical results to #2. All the code works fine when running without --noconsole or running directly from Python. Any ideas on how to run a child subprocess successfully, but without opening a console window? Thanks!
