Hi! Bob
  As I tried to make shared dynamic library, ld command shows some error message
  ld: Undefined symbols: 
  I do not know which lib including this "dyld_stub_binding_helper" even though I used "nm" to find it. The list libs that I used is 
  -L/usr/lib -L/usr/local/lib -lpython -lc -lm -lSystemStubs -lSystem_profile 
  It may need more lib? anyone knoew. This may be old problem that people had.

No. As I've said three or four times already in this thread, that is 
not an option because pythonw doesn't exist. It's just a shell 
script that starts the Python interpreter from within an application 
bundle. It's the exact same interpreter that is used when you type 
python, it's just symlinked to somewhere else. To get that behavior 
you MUST use an application bundle. It's a simple matter of creating 
a few directories and an Info.plist and putting your application in 
there. Quite trivial if you're using Xcode because it's got support 
for application bundles, where the normal GCC toolchain does not.

No, it's not a lot of changes. Trivially you could remove your 
Python initialization/finalization code and change the rest of main() 
to be callable from Python and turn that into an extension module. 
20-30 minutes work at most. That would solve the immediate problem 
because you wouldn't be embedding Python anymore.
