Hi,
I'm working with an embedded Python C++ application. This application
allows me to run python scripts alright. However, one of my scripts
requires importing extension modules such as socket. The script bombed
when I tried to run it. It turned out that this application only runs
Python scripts that use Pythoncore modules only.
Unfortunately I do not have access to the source code of this
application
at this point. In desparate attempt, I rebuilt the _socket.pyd and
placed it
in the path where the python.dll (pythoncore library) of this tool
resided.
Well, the script bombed again. However through the debugger's trace I
found something interesting.
1. C:\AutoScript\p ython.dll was loaded <--- embedded in app
2. D:\python\DLLs\ _socket.pyd was loaded <---- came with Python I
installed on
my machine
3. C:\WINNT\System 32\python23.dll was loaded <--- Python I installed
on my machine
Apparently the application was able to find and load _socket.pyd
(hmmm,
not the one I put under C:\AutoScript). However, socket lib uses
pythoncore, hence, python23.dll was loaded. Since 2 different versions
of Pythoncore libs got loaded, it got confused and crashed. This very
likely has something to do with the path setting. I checked the
Windows registry. I could not find any key with reference to
python23.dll so I could trace where the key was used.
Your time is appreciated.
