[C++-sig] Build Errors Making the "quickstart" Demo Project

[Paul Kroitor]

Hello all,

 

We are adding a python scripting layer on top of an existing largish C++
app, and are hoping to use Boost.Python to accomplish this. So far, it's
hasn't been going very smoothly, but I think we are nearly to the point
of getting the demo program to compile.

 

For the most part, we are following the instructions here:

http://www.boost.org/doc/libs/1_47_0/libs/python/doc/building.html

 

but have also had to use hints from here

http://stackoverflow.com/questions/2629421/how-to-use-boost-in-visual-st
udio-2010

and several other forums to get as far as we have (who / where should we
report manual errors to?).

 

I don't think we are doing anything non-standard - we certainly aren't
trying to - but perhaps some of the issues we are seeing come from using
Python 3.2. To complete the list, we are also using MSVC 10.0 SP1 and
Boost 1.47 on Windows 7 32-bit platform.

 

Currently, we are trying to get the "quickstart" example working and are
stuck on an error in the build of  "embedding.cpp":

 

(note that for clarity I've rerun the build a second time so that it is
only trying to build the failed modules)

With all the templates and overloads, this is getting too technical for
to solve here. I am hoping someone here will recognize this error or
understand what's causing it.

 

Thanks in advance for any help or guidance anyone is able to give.
