Up to date Arch Build trying to build master as of today, I get the following build error. Not entirely sure how these are supposed to be created from the Qt *.ui files but these elements are present there.
src/library/dlgtrackinfo.cpp: In member function ‘void DlgTrackInfo::init()’:

scons: *** [lin64_build/library/dlgtrackinfo.o] Error 1
This error indicates that you are compiling outdated code generated from the .ui files.
If you are using SCons 3 then this is a known issue. The dependencies between the .ui and the corresponding .cpp/.h files that need to be generated are either broken or non-existent. You need to downgrade to SCons 2.5.1.
