|

| 151 | The BLFS editors recommend installing <application>Qt5</application> in a
|
---|
| 152 | directory other than <filename class="directory">/usr</filename>, ie
|
---|
| 153 | <filename class="directory">/opt/qt5</filename>. To do this, set the
|
---|
| 154 | following environment variable:
|
---|
| 155 | </para>

|
---|
| 160 | <para>
|
---|
| 161 | Sometimes, the installation paths are hardcoded into installed files.
|
---|
| 162 | This is the reason why <filename class="directory">/opt/qt5</filename>
|
---|
| 163 | is used as installation prefix instead of <filename
|
---|
| 164 | class="directory">/opt/qt-&qt5-version;</filename>. To create a
|
---|
| 165 | versioned <application>Qt5</application> directory after the
|
---|
| 166 | installation is complete, you may rename the directory and create a
|
---|
| 167 | symlink:

|

|
---|
| 172 |
|
---|
| 173 | <para>
|
---|
| 174 | Later on, you may want to install other versions of
|
---|
| 175 | <application>Qt5</application>. To do that, just remove the symlink
|
---|
| 176 | and use <filename class="directory">/opt/qt5</filename> as the
|
---|
| 177 | prefix again. Which version of <application>Qt5</application> you
|
---|
| 178 | use depends only on where the symlink points.
