Is it definitely the linking? Or should I check the compiler
arguments as well?
There are 8 libraries (-lQtTest -lQtCore -lQtGui -lxslt -lxml2 -lQtCore -lQtXmlPatterns
-lQtXml)
plus an explicit libapiextractor.so.0.10.1. Did you run nine tests, replacing the pieces
one-by-one with their Fedora 29 versions?
