Unresolved external symbol when building python

[tglauner]

I am trying to use the Python wrapper for Quantlib but have trouble building and installing the python part. I am on XP and use VS 2008 with boost 34.

Could you please guide me on how to fix this.

I actually resolved the issue by adding '/EHsc' to the extra compile flags. Apologies for the original post.

No apologies required--in fact, it's good to have the problem and
solution archived here.
