This happens when I try to compile the github sources
(https://github.com/podofo/) I have also tried to compilethe stable version but
this fails with gcc-13. So I tried tocimpile with gcc-10 but this fails again
because libcppunit.sois linked against
libstdc++.so.6 => /usr/gcc/13/lib/amd64/libstdc++.so.6
Does anybody have an idea how to compile PODOFO?
Kind regards,A.S.
