Set Installed File Permissions for Linux

Here is a guide to set permissions for installed files on linux.

In your .pro file, change QMAKE_INSTALL_FILE and QMAKE_INSTALL_PROGRAM to the following:

QMAKE_INSTALL_FILE = install -m &lt;permission octals&amp;gt; -p -o &lt;user&amp;gt; -g &lt;group&amp;gt;<br />QMAKE_INSTALL_PROGRAM = install -m &lt;permission octals&amp;gt; -p -o &lt;user&amp;gt; -g &lt;group&amp;gt;

where:
* <permissions octals&gt; is the standard linux permissions octals (ex: 755).
* <owner&gt; is the owner of the file. This parameter can be ommited.
* <group&gt; is the group owner of the file. This parameter can also be ommited.

Here is an example implementation. In this example, I install my binary in the folder /opt/myApp and give it permissions 6755 with root as the owner and root as the group owner.

unix {<br /> target.path = /opt/myApp<br /> INSTALLS += target

QMAKE_INSTALL_FILE = install -m 6755 -p -o root -g root<br /> QMAKE_INSTALL_PROGRAM = install -m 6755 -p -o root -g root<br />}
