Hello,

I have a Qt application which i want to port on maemo.
I tested it on scrachbox and it works decent but i want to install it on N900.

The application contains 2 modules.
-1 GUI created in Qt.
- from the GUI another process is started. This process is doing the background work. About this process, it is quite big around 10M and I have it compiled for ARMEL.

When I'm creating the package using this command:
dpkg-buildpackage -sa -rfakeroot
my background process is not included.

How should i add this process to the package and where should it be installed?

Thanks

Problem solved by calvin_42.

One more question:

The background process is installed now in the /opt/my-app/backgroundp.

Mainly at one point it is started and it must create a text file.
The file is read after that by the Qt GUI when the background process is finished.

I think my process does not have the rights to create a new file in /opt/my-app/ directory.

How can i change this from the installation package?

Thanks

One more question about packing
in the data folder i have a subdirectory with a lot of files inside?

They should all be copied on the phone.
Is it possible to make one install tag in the src.pro and copy everything from data/subdir/ in one go or i have to make a tag for every file i want to be copied on the phone?

I has to be set in your .pro file.

Section INSTALLS

ex :

Code:

INSTALLS += backgroundprocess

backgroundprocess.path = $$PREFIX/opt/yourprog/
backgroundprocess.files += data/scripts/yourprog

You'll find more information using the search function or google.

For example in the same directory that your GUI app, ie /opt/yourprog/.

there are post installation scripts ( postinst ) in the debian folder. They will exist as postinst.ex, make sure you remove the extension .ex.
insert a command like this in it

chown -R user <package_path>

that should give the ownership of the package folder to the "user" user that will be exectuing the process.

Can you explain a little more clear how to create the postinstall file.
I removed the .ex and i added just before the end of the file your command:

Code:

#DEBHELPER#
chown -R user /home/opt/myapp

exit 0

if i run the command on the phone using sudo gain root and run again my process everything works fine

but when i install the package i still have the same problem.

should i add in the install rules the postinstall directory?

Thanks, flgor.

can you attach your source/postinstall script please.
Did you modify the postinst file in your debian folder ?
Did you then install the package on your phone
using dpkg -i <package>
and then run your app and it didnt work ?

Why /home/opt/myapp ? Shouldn't it be /opt/myapp instead ?

See :

/opt is a link to /home/opt

This is the postinst file from debian folder

Code:

#!/bin/sh
# postinst script for myapp
#
# see: dh_installdeb(1)

set -e

# summary of how this script can be called:
#        * <postinst> `configure' <most-recently-configured-version>
#        * <old-postinst> `abort-upgrade' <new version>
#        * <conflictor's-postinst> `abort-remove' `in-favour' <package>
#          <new-version>
#        * <postinst> `abort-remove'
#        * <deconfigured's-postinst> `abort-deconfigure' `in-favour'
#          <failed-install-package> <version> `removing'
#          <conflicting-package> <version>
# for details, see http://www.debian.org/doc/debian-policy/ or
# the debian-policy package


case "$1" in
    configure)
    ;;

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

    *)
        echo "postinst called with unknown argument \`$1'" >&2
        exit 1
    ;;
esac

# dh_installdeb will replace this with shell code automatically
# generated by other debhelper scripts.

#DEBHELPER#

chown -R user /home/opt/myapp

exit 0

It does not work.
