I'm trying to do some debugging of python extensions on Windows2K. MS
Visual Studio (.NET) says it can't find the debug version of the
python libraries. (The message is "python.exe does not contain any
debugging information".) I installed the binaries from the Windows
installer. How should I get the debug libraries? Or is that even
what I need? I'm kind of new to Windows, and Visual Studio in
particular, so maybe I'm way off base.
thanks,

If you are using the ActivePython distribution the debug libraries are
made available in a separate package here: ftp://ftp.activestate.com/ActivePython/etc/
For example the debug libs for ActivePython 2.3.2 are:
ActivePython-2.3.2-230-win32-ix86.debug.zip

See my recent post... http://groups.google.ca/groups?q=deb...hon.org&rnum=2
(all one line). You probably don't want to debug *everything*, just
your particular extension, and this recipe allows that fairly readily
w/out requiring getting every single dependency built against debug
Python (which can be a royal PITA).

in our company, we do not link to debug third party libraries. i'm embedding python (using visual studio) and run into
the same problem. we now resort to undef'ing _DEBUG before including the python header files and everything works
correctly. if you look in the python header files, you will see that when _DEBUG is defined, there is a #pragma to link
to pythonXX_d.lib. when _DEBUG is not defined it will link to pythonXX.lib. other's may disagree about this approach,
but so far it works well and we don't have any memory problems at all.
for extensions using distutils here's another option which i prefer, since you can do this on a case-by-case basis
instead of modifiying msvccompiler.py :
add this line to setup in your setup.py file:
extra_compile_a rgs = ['/Od /Z7'],
extra_link_args = ['/DEBUG'],
since these options will be placed after the compile/link options that distutils uses, these options will be used,
overriding the options in msvccompiler.py .

these should be mutally exclusive (they are the same Python version)? Can

You could _try_. :) No guarantees because we certainly don't test that.
ActivePython is fully binary compatible with python.org's Python and I
would presume with Enthought's distro as well, so it should basically
work. You might run into trouble when you start trying to uninstall
everything, though.

Okay, I installed ActivePython and the debug libraries. I'm also using
ActiveState's Visual Python. I have a Python driver script which calls
into my Python extension (written in C). How do I get the debugger to
break in the Python script, and then later in my C code? I can get it to
do one or the other by changing which is the "Startup Project". But when
I'm debugging I really need both.
Thanks,

I am no expert on distutils but that module is a part of the distutils
and is called by the distutils framework _iff you are using distuils to
build your Python extension_. http://aspn.activestate.com/ASPN/doc...dist/dist.html
