It seem it does not work with the version of cppunit thatg my system provides, is this right? How can I fix this problem?
Kind regards,

You didn't follow the new issue form, and also you are almost certainly using PoDoFo 0.9.x, which doesn't have a maintainer. Your issue may be fixed by this commit, or at least we had some issues regarding cppunit and PdfString and that commit fixed them. You can try the 0.9.x branch, or better upgrade to 0.10.x. Alternatively you should investigate the compilation issue yourself with 0.9.x and supply a patch.
