Title: Debug Build of python Interpreter fails to import Python Module (*.pyd)

Try a second -v and you will then see that python is trying to load pysp_d.pyd. The _d is use added to all pyd's when using

the debug version of python. This is because C/C++ code compiled against the python headers with DEBUG defined

produces code that is incompatible with non-DEBUG builds.

Subject: Debug Build of python Interpreter fails to import Python Module (*.pyd)

Hi,

we have a problem with debugging a Python module, namely pysp (http://www.garshol.priv.no/download/software/pysp/).
We managed to build pysp.pyd, both the debug and release version, with the ActivePython 2.0 Build 202.
We did build and test pysp under Windows NT 4.0 sp6 with Visual Studio 6 sp4.

The problem we have now:
when we use "python_d -v ..." to invoke a Python script containing "import pysp", we get constantly the error message

ActivePython 2.0, build 202 (ActiveState Tool Corp.)
based on Python 2.0 (#8, Mar 20 2001, 15:44:34) [MSC 32 bit (Intel)] on win32
Type "copyright", "credits" or "license" for more information.
Traceback (most recent call last):
  File "..\..\..\pysp_0.01\pysp\doc\demo.py", line 5, in ?
    import pysp, sys
ImportError: No module named pysp
# clear __builtin__._
# clear sys.path

we checked everything, both the PythonPath and the Path environment variables are set to include the absolute path to the directory containing both pysp.pyd and sp13.dll. Also using the Dependency Walker does not show any problem.

When we do the same with the release version python.exe we built from the same sources (with the release built of pysp.dll), everything works fine.

Is there a difference in the lookup mechanism for Python modules (*.pyd) between Debug and Release Builds?
