C++ library to load Excel (.xls) files [closed]

Question

I'm looking for a free C++ library that can load .xls files in both Windows and Linux. If I had to make a choice, Linux would be the bare minimum.

I've tried LibXL, but got this amazing error:

"can't read more cells in trial version"

So now I'm on the hunt for a free version :), unfortunately xlsLib doesn't provide the ability to load existing .xls files.

Thanks
