How to add permissions to files installed by dpkg-buildpackage or debuild

rated 0 times [ 2] [ 0] / answers: 1 / hits: 5009 / 2 Years ago, sun, june 5, 2022, 4:32:22

I build a package from my own source using dh_make and dpkg-buildpackage. The install-file in /debian specifies the destinations for the project files. To make the installed program work, they need to be executable / have execution permissions with chmod. In particular it is about a python script and a .desktop-file.

How do I set those permissions in setup? By only copying them to their destinations it is not done. It would be ok for me if I could trigger a command at the end of setup, or something like this, but don't know how to include this.

The .desktop file doesn't need execution permissions, your .py script does.

braiam@bt:~$ ls -l /usr/share/app-install/desktop/deluge.desktop 

-rw-r--r--. 1 root root 1276 Aug  6  2012 /usr/share/app-install/desktop/deluge.desktop

braiam@bt:~$ ls -l /usr/bin/deluge

-rwxr-xr-x 1 root root 289 Jan 27  2013 /usr/bin/deluge

You should before packaging have set the executable bit on the python script, that dpkg will take care of the rest.

The .desktop file is a configuration file read by xdg, and has it own variables set to execute the needed binary:

cat /usr/share/app-install/desktop/deluge.desktop

[...]

GenericName=BitTorrent Client

X-GNOME-FullName=Deluge BitTorrent Client

Comment=Download and share files over BitTorrent

Exec=deluge-gtk %U

Icon=deluge

Terminal=false

Type=Application

Categories=Network;FileTransfer;P2P;GTK

StartupNotify=true

MimeType=application/x-bittorrent;x-scheme-handler/magnet;

As you wan see it has a Exec variable that takes care of the execution when the file is accessed.
