Using update-alternatives when deploying two versions of Qt on OpenSuse Linux
-
I have version of Qt installed from repositories of OpenSuse Linux. But it lacks some of the Qt components and I needed to install SDK.
When you install two versions of Qt on Linux you need to tell the system which compiler to use.
I used the following command to add newer qmake as alternative to preinstalled qmake: "sudo update-alternatives --install /usr/bin/qmake qmake /opt/QtSDK/Desktop/Qt/4.8.1/gcc/bin/qmake 10"
Command output:
"Update-alternatives: warning: /etc/alternatives/qmake has been changed (manually or by a script). Switching to manual updates only.
Update-alternatives: using /opt/QtSDK/Desktop/Qt/4.8.1/gcc/bin/qmake to provide /usr/bin/qmake (qmake) in auto mode.
update-alternatives: warning: not replacing /usr/bin/qmake with a link"Problem is when I execute qmake still old version is used.
Then I ran command "sudo update-alternatives --display qmake"
Output: "qmake - auto mode
Link currently points to /opt/QtSDK/Desktop/Qt/4.8.1/gcc/bin/qmake
/opt/QtSDK/Desktop/Qt/4.8.1/gcc/bin/qmake - priority 10
Current 'best' version is '/opt/QtSDK/Desktop/Qt/4.8.1/gcc/bin/qmake' "I also get strange output from command: "sudo update-alternatives --config qmake"
"There is only one alternative in link group qmake: /opt/QtSDK/Desktop/Qt/4.8.1/gcc/bin/qmake
Nothing to configure.
update-alternatives: warning: forcing reinstallation of alternative /opt/QtSDK/Desktop/Qt/4.8.1/gcc/bin/qmake because link group qmake is broken.
update-alternatives: warning: not replacing /usr/bin/qmake with a link"That's the point where I got stuck would like to ask for a help if somebody knows the question.

Hi!
Is all that really needed? Why not just call the right qmake?
And in QtCreator you can define two Kits one for each Qt version. -
