That is a surprise. I thought that qt used qmake as part of its own build process, and put qmake into the bin directory when qt was installed. >So, in other words: Qt4 and its headers may be installed but not qmake.

Cross platform (Windows/Linux projects) most likely depend on qmake to get things right. So, what about Windows/Linux users? >>1. find qmake in the PATH >>2. use pkg-config to find qmake >>3. if 1 and 2 are the same qmake, then use the info from pkg-config >>4. if pkg-config was not found, or it points to a different qmake than >>the one in the users PATH, then use qmake to setup the paths for the >> build. > >Use pkg-config to find qmake? Why? If pkg-config is found, ask it where >QtCore is, what its CXXFLAGS are, what the rpath flags are, where moc, >uic, etc. are. So, if someone builds qt, then puts that qt bin their PATH, but does not set the pkg-config environment variable, they will get the wrong qt if there are two on the system. Can pkg-config handle more than one build of QT? I really just want this to work for the most possible cases across as many platforms as possible. -Bill _______________________________________________ Kde-buildsystem mailing list [email protected] https://mail.kde.org/mailman/listinfo/kde-buildsystem
