| That's an easy one!
| Look into CGIHTTPServer.py, near line 232:
|             if self.is_python(scriptfile):
| =>              interp = sys.executable
|                 if interp.lower().endswith("w.exe"):
|                     # On Windows, use python.exe, not pythonw.exe
|                     interp = interp[:-5] + interp[-4:]
|                 cmdline = "%s -u %s" % (interp, cmdline)
|
| It tries to start 'sys.executable' with the python cgi script.  Normally
| sys.executable is the Python interpreter, but for a py2exe'd script this
| is the running executable (which is no longer a usual Python
| interpreter).
|
| Changing this line to 'interp = r"c:\python23\python.exe"' makes the
| frozen script work (although then the Python installation is required
| again).
|
| (A few minutes later, looking at CGIHTTPServer.py again)
| It seems you have to hack this module so that the code block starting at
| line 270 is used, which says:
|         else:
|             # Other O.S. -- execute script in this process
| and then it works fine.

Hi Thomas,

I suspected something along those lines....

I'll give the hack a go!

Thanks!
