9 | <title>Choosing Qt Program Versions</title>
|
---|

|
---|
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 > /usr/bin/setqt4 << 'EOF'
|
---|
17 | <literal>if [ "x$QT5DIR" != "x/usr" ] && [ "x$QT5DIR" != "x" ]; then pathremove $QT5DIR/bin; fi
|
---|
18 | if [ "x$QT4DIR" != "x/usr" ]; then pathprepend $QT4DIR/bin; fi
|
---|
19 | echo $PATH</literal>
|
---|
20 | EOF</userinput></screen>
|
---|
21 |
|
---|
22 | <screen role="root"><userinput>cat > /usr/bin/setqt5 << 'EOF'
|
---|
23 | <literal>if [ "x$QT4DIR" != "x/usr" ] && [ "x$QT4DIR" != "x" ]; then pathremove $QT4DIR/bin; fi
|
---|
24 | if [ "x$QT5DIR" != "x/usr" ]; then pathprepend $QT5DIR/bin; fi
|
---|
25 | echo $PATH</literal>
|
---|
26 | EOF</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>
