Hi Eike,
Thanks for the quick response. The things that are not found are for
isntance, "/usr/include/qjsonrpc/qjsonrpcmessage.h". I can fix this
manually by adding "/usr/include" to my INCLUDEPATH - no problem, but
definitely wasn't a requirement on the exact same machine with the qt
4.8.6 install (maybe a more basic question: is this just something
that changed in 5.x mkspecs?). My compile lines with 4.8.6 installed
add -I/usr/include to the compile lines, while the 5.3.2 install does
not. Additionally, adding "-L/usr/lib" to my LIBS line in the pro file
with 5.3.2 still breaks and can't find files that are definitely
there. I'll pour through this "qmake -d -d -d" now and see if I can
provide any more information.
