No, not really. We can build two different versions of poppler, one with Qt3 and one with Qt4. It does get a little tricky though. I ran into the same problem with qca (Qt Crypto Architecture). My solution was to build a library called qca2. For poppler, we could build a libpoppler-qt3 library and fix Trinity to use it. Then we could build libpoppler-qt which uses Qt4 for everybody else. A quick check shows that the current poppler is version 0.18.2 and that only supports Qt4. Specifically, -lQtGui -lQtXml -lQtCore. For kdegraphics, we would need an older version. What I think we should do is just update poppler for general use and I'll add a page to Trinity with the older poppler. The change log says Qt3 was removed with version 0.17, so I'd need to go back to at least version 0.16. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
