Comment 14 for bug 2003259

For libcupsfilters the warnings are harmless and there are only 2 types signalling deprecations of feature in QPDF.

Very long term solution is replacing QPDF by PDFio (https://github.com/michaelrsweet/pdfio), to have simple C instead of C++ for easier maintenance

But for now, we will update the code to not use the deprecated features any more.

One deprecation is solved upstream now:

    https://github.com/OpenPrinting/libcupsfilters/commit/46f6896

The second is more complex to solve but one can suppress the warnings when building the package:

    CXXFLAGS='-DPOINTERHOLDER_TRANSITION=0' ./configure
    make

This would at least make warnings about atual problems more visible.

After applying above methods I currently do not get any warning at all any more.
