[XML-SIG] PyXML setup.py install - MSVC Compile Errors (error LNK2019: unresolved external symbol __imp__)

[Paul Hudson]

Hello Everyone,

I am attempting to setup PyXML under ActiveState's 64bit build of Python.  I
am running WinXP x64 on an AMD Opteron proc.
I am using Visual C++ 2003.
I referenced this page to get as far as I have:
http://www.vrplumber.com/programming/mstoolkit/   (I made the recommended
changes to msvccompiler.py)


When I run "python setup.py install", compilation gets to the linking stage
and then I get a lot of errors similar to this:
pyexpat.obj : error LNK2019: unresolved external symbol __imp__PyTuple_New
referenced in function _call_character_handler


I have found some info pointing to the "__imp__" prefix being the problem
and that this is caused by using __declspec( dllimport ).

I am not very experienced with compilation flags, definitions, declarations,
etc.


If anyone can offer some insight into what is causing these errors, it would
be very appreciated.



Thanks,
Paul
