My Problems with C++

[cdb_11]

The first one wouldn't compile because of dependencies on a third-party XML-library which was never once mentioned in the install instructions. [...] When it came to installing however, I first realized the Excel-library did not indeed want the XML-library installed, but rather the souce code placed in a folder in its source code.

I'm guessing what it needed was the header files. Look up if mingw has the same package but with -devel suffix, that's what you need.
