9 <title>Choosing Qt Program Versions</title>
10
11 <para>If you install both Qt4 and Qt5, you can use some simple
12 scripts to select the currently active set of Qt programs. As the
13 <systemitem class="username">root</systemitem> user, create
14 the following scripts:</para>
15
16<screen role="root"><userinput>cat &gt; /usr/bin/setqt4 &lt;&lt; 'EOF'
17<literal>if [ "x$QT5DIR" != "x/usr" ] &amp;&amp; [ "x$QT5DIR" != "x" ]; then pathremove $QT5DIR/bin; fi
18if [ "x$QT4DIR" != "x/usr" ]; then pathprepend $QT4DIR/bin; fi
19echo $PATH</literal>
20EOF</userinput></screen>
21
22<screen role="root"><userinput>cat &gt; /usr/bin/setqt5 &lt;&lt; 'EOF'
23<literal>if [ "x$QT4DIR" != "x/usr" ] &amp;&amp; [ "x$QT4DIR" != "x" ]; then pathremove $QT4DIR/bin; fi
24if [ "x$QT5DIR" != "x/usr" ]; then pathprepend $QT5DIR/bin; fi
25echo $PATH</literal>
26EOF</userinput></screen>
27
28 <para>You should now be able to use the appropriate Qt version by running
29 <command>source setqt4</command> or <command>source setqt5</command> as
30 desired. (Setting the PATH wont work in a subshell.) Another technique that
31 can be used is to create appropriate alias additions to your ~/.bashrc like
32 <command>alias setqt4='source setqt4'</command>.</para>
