hi,

I'm developing an application with qt creator for n900.
In my app I need to save some stuff to a config file. This file should be located at "~/.myapp/config.xml".
Creating and editing the file at runtime is no problem but how do I add it to the debian package so that it will be installed along with the binary?
That should be the standard way in debian, should it?

I search google and found many stuff regarding debian packaging but I'm didn't find a suitable answer.

No, you should never be installing a user config file as part of the package. Packages should only install system-wide config files (usually in /etc), or install the config files to a shared directory (under /usr/share usually), where they can be copied into the user directory when first run.

use the postinst file
u can create a config to write or u can move a config file after the installation directly using the postinst file to add at the DEBIAN folder

So in my postinst.ex file I have now the following code:

Code:
[...]
case "$1" in
    configure)
        mkdir -p /etc/myapp/
        echo "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>" > /etc/myapp/config.xml
        echo "<root>" >> /etc/myapp/config.xml
        echo "</root>" >> /etc/myapp/config.xml
    ;;

    abort-upgrade|abort-remove|abort-deconfigure)
    ;;

    *)
        echo "postinst called with unknown argument \`$1'" >&2
        exit 1
    ;;
esac
[...]
And that in my postrm.ex file:

Code:
case "$1" in
    purge|remove|upgrade|failed-upgrade|abort-install|abort-upgrade|disappear)
        rm -r /etc/myapp/
    ;;

    *)
        echo "postrm called with unknown argument \`$1'" >&2
        exit 1
    ;;
esac
Is that correct? I haven't tested it.

Something doesn't work. The directory and file under /etc isn't created when I test my project in qt creator.

Also when I edit the files in the myapp-build-maemo/debian directory nothing happens.

This should be done automatically because qt creator launches dpkg remotely on the device.

postinst.ex is the example file isn't it? Have you actually renamed it to myapp.postinst?
