Set Installed File Permissions for Linux
NOTE: This information is outdated for newer Qt versions! No direct replacement exists yet; it is possible to assign the .commands property of an install target to override the built-ins.
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 <permission octals> -p -o <user> -g <group>
QMAKE_INSTALL_PROGRAM = install -m <permission octals> -p -o <user> -g <group>
- <permissions octals> is the standard linux permissions octals (ex: 755).
- <owner> is the owner of the file. This parameter can be ommited.
- <group> 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.
target.path = /opt/myApp INSTALLS += target
QMAKE_INSTALL_FILE = install -m 6755 -p -o root -g root
QMAKE_INSTALL_PROGRAM = install -m 6755 -p -o root -g root
