I think you misunderstood me here. I meant that mkspecs moves from "datadir" to "archdatadir" because I'm splitting the arch-dependent files from the arch-independent ones. Code that tries to find the mkspecs will need to use QLibraryInfo::ArchDataPath or qmake -query QT_INSTALL_ARCHDATA, instead of what they do today. And I'm arguing that it is acceptable because the mkspecs are really no longer compatible with Qt 4, so any code that tried to parse them will need to be updated considerably. I don't expect anyone to be doing this, except for our own tools (qmake, lupdate, lrelease, Creator). However, the actual installation paths will probably not change: /usr/lib/qt5/mkspecs for installed builds, QTDIR/mkspecs elsewhere. There are two proposals here to be decided upon: a) the DATADIR and ARCHDATADIR split, which causes the source-incompatible change for the mkspec parsing. b) the default values for those two: I'm proposing ARCHDATADIR=LIBDIR/qt5 and DATADIR=PREFIX/share/qt5 for installed builds only, ARCHDATADIR = DATADIR PREFIX elsewhere. I really, really, really want A, but I don't really mind either way for B. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
