I've been having some build problems, probably of my own fault. My make distclean failed part of the way though, but it got far enough that the configure script would proceed. ~/qt5/qtdeclarative/src/3rdparty/masm/yarr/YarrPattern.cpp:39:10: fatal error: 'RegExpJitTables.h' file not found Advice on how I can salvage my build?
