Hi,

I was just wondering, is there a "correct" or "preferred" way of setting up the path and other environment variables for Qt 4 development/build using qmake and all - on a CentOS 6 system?

I mean, this does not work out-of-the box, at least if you have build files that assume "qmake" may be executed just like that - as there is no Qt 4 qmake on the path, although "qmake-qt4" is available. Also, if qt3-devel is installed, and the default path setup is used, "qmake" will point to the Qt 3 version, as the package includes a profile.d file that modify the path in such a way. Which also sets up other Qt related variables, I believe. There is no such file in qt4-devel, however.

I know ways to set up everything so that this works as expected, of course, but it would be interesting to know how the packagers intended it to be done. Are you expected to edit login files by hand? That's sort of surprising in this day and age... Or is the thinking that the suffixed ("-qt4") version of commands will always be used? Or that everyone will be using plain make with pkg-config? Or is there some other mechanism that should to be used to select the right Qt version?
