Re: Qt 4 installation and configuration woes

[David McLean]

Salvador, Thanks for your help! I'm now building the project successfully, but something is corrupting my build. When I try to run the binary here's what I get: [r...@...]# ./controller_v_0-01 Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed Segmentation fault I believe the session management error is because I've logged in as "su", so under normal user session, I get just the segmentation fault: [dmcl...@...]$ ./controller_v_0-01 Segmentation fault And by the way, the QtCreator environment still has the same issues as before. Ideally, I would like to migrate to that environment, I think! Thanks again for your help!

Let us know if this gets you going.

Now to the point: Has anyone had any issues with installing Qt4 and getting it working properly? It seems as though the basic Qt4 package does not include the make utility "qmake". Therefore I tried uninstalling it and downloading direct from Trolltech and building it from source which still leaves me some issues. I do appear to have qmake but I seem to have some environment variable issues. When I try to compile a project, I get the following error response: [r...@dhcp...]# qmake Could not find mkspecs for your QMAKESPEC(linux-g++) after trying:         /usr/local/Trolltech/Qt-4.6.2/mkspecs Error processing project file: /home/dmclean/Desktop/VIIBRE/StageController/controller_v_0-01/controller_v_0-01.pro Looks like I've got something looking in the wrong place but the "/usr/local/Trolltech/Qt-4.6.2/mkspecs" is the correct path to the "mkspecs" directory. I do not have a lot of experience with system/environment variables. Has anyone experienced anything similar to this? Thank you for your time. -- David L.
