I just made a simpler step by step process:

1. Open MADDE terminal

2. Execute: mad pscreate -t qt_simple qtx

3. Place a 64x64 image named qtx.png in the qtx folder. (NOT the src folder)

4. Create a file named qtx.desktop in qtx folder with this content:

Code:

[Desktop Entry]
Encoding=UTF-8
Version=0.1
Type=Application
Name=qtx
Exec=/usr/bin/qtx
Icon=qtx
X-HildonDesk-ShowInToolbar=true
X-Osso-Type=application/x-executable

5. Add these lines to the end of qtprog.pro:

Code:

PREFIX = ./debian/qtx/usr

unix {
BINDIR = $$PREFIX/bin
DATADIR =$$PREFIX/share

DEFINES += DATADIR=\"$$DATADIR\" PKGDATADIR=\"$$PKGDATADIR\"

#MAKE INSTALL

INSTALLS += target desktop icon64

  target.path =$$BINDIR

  desktop.path = $$DATADIR/applications/hildon
  desktop.files += qtx.desktop

  icon64.path = $$DATADIR/icons/hicolor/64x64/apps
  icon64.files += qtx.png
  

}

6. Exectute these commands in MADDE terminal:

Code:

cd qtx
mad qmake
mad dpkg-buildpackage
mad remote -r N900 send ../qtx_0.1_armel.deb
mad remote -r N900 install qtx_0.1_armel.deb

Thats it, its now installed with shortcut and icon!

(shows a blue icon before you restart the device)

Can someone show me how the debian/postinst file is supposed to look like to update the icon without the need for a restart ?

Here is an example. Line 6 does the trick. But be aware that there is a bug in the platform itself, so that it might not work.

OK, discovered how to remove my package from the N900 too

In X-Terminal

Code:

sudo gainroot
dpkg -r <packagename>

That appears to be it!

OK, Here is the full guide with the final 2 steps included (update icon cache and uninstall). It is supposed to be step by step guide onhow to take a (simple) Qt app and package and deploy it with an Icon using Madde.

The project I have is simple, 1 window called mainwindow.

Note: As a convention I like to keep all my code together, so I have created any extra files in the "src" folder.

Steps:

1. Create project through Madde

2. Edit and test with QT Creator

3. Once ready to deploy create a clean empty top level folder "<projectname>-0.x" where x is your revision number e.g. "c:\Madde\0.5\home\shep\wwcalc-0.1"...In the OS
Note: the following 3 steps apply each time you go to build.

3.1 ensure there is no "debian" folder at the same level as "src"
3.2 ensure there is no folder structure called "<projectname>-0.x-orig" left over from a failed compile
3.3 remove old compiles from the Madde\home\user (e.g. C:\Madde\0.5\home\Shep) folder.

4. Copy the "src" folder from the tested Qt project into the "<projectname-0.x" folder

5. Create (or obtain) an application Icon. This should be a 64x64 png. Call it <projectname>.png and place it in the "src" folder.

6. Again inside the "src" folder create a new file called "<projectname>.desktop"

Code:

[Desktop Entry]
Encoding=UTF-8
Version=0.x
Type=Application
Name=<Long Descriptive Project Name>
Exec=/usr/bin/<projectname>
Icon=<projectname>
X-HildonDesk-ShowInToolbar=true
X-Osso-Type=application/x-executable

7. Again inside the "src" folder create a new file called "<projectname>.service" which looks like this

Code:

[D-BUS Service]
Name=org.maemo.<projectname>
Exec=/usr/bin/<projectname>

8. Inside the "src" folder added a file called "src.pro". Getting this right is the key to getting the Makefile correct and hence the install working. At the end of this file there is a section called "INSTALLS += "...for every file you want installed in a location you need an entry here. I've colour coded the 4 installs below for clarity.

Code:

TARGET = wwcalc
TEMPLATE = app
SOURCES += qtmain.cpp \
    mainwindow.cpp 
HEADERS += mainwindow.h 
FORMS += mainwindow.ui 
PREFIX = ../debian/wwcalc/usr

unix {
BINDIR = $$PREFIX/bin
DATADIR =$$PREFIX/share

DEFINES += DATADIR=\"$$DATADIR\" PKGDATADIR=\"$$PKGDATADIR\"

#MAKE INSTALL

INSTALLS += target desktop icon64 service

  target.path =$$BINDIR

  desktop.path = $$DATADIR/applications/hildon
  desktop.files += wwcalc.desktop

  icon64.path = $$DATADIR/icons/hicolor/64x64/apps
  icon64.files += wwcalc.png
  
  service.path = $$DATADIR/usr/share/dbus-1/services
  service.files += wwcalc.service

}

9. Up one level and inside the new top level folder (i.e. "c:\Madde\0.5\home\<YOU!>\<projectname>-0.x" ) created a file called "<projectname>.pro" with the following exact contents

Code:

TEMPLATE = subdirs
SUBDIRS  = src

10. In Madde make sure the runtime is up and connectible (described here) and then execute

Code:

mad dh_make --createorig --single -e foo.bar@gmail.com -c gpl

11. Step 10 creates a debian folder at the root level, Go there and edit the "postinst.ex" file

Code:

#!/bin/sh
# postinst script for <projectname>
#
# see: dh_installdeb(1)

gtk-update-icon-cache -f /usr/share/icons/hicolor

#maemo-select-menu-location <projectname>.desktop

exit 0

12. Again in Madde

Code:

mad qmake
mad dpkg-buildpackage
mad remote -r org.maemo.<projectname> send ../<packagename>_0.x-1_armel.deb
mad remote -r org.maemo.<projectname> install <projectname>_0.2-1_armel.deb

13. Uninstalling - from an X_Terminal

Code:

sudo gainroot
dpkg -r <projectname>

I hope this helps/works!

Many thanks to many users who helped me understand this structure especially too, Salser and danielwilms.

Please note that icon cache was dropped since PR1.1, so software targeting PR1.1 and future releases don't need this file.

Please wikify this tutorial[1], these kind of tutorials get lost over time here at TMO.

Thanks for your contributions.

If we are going to put this on a wiki I dont think the guide shep made is any good, its too complicated. You realy dont need to do all those steps, just look at my post at the top of this page..

Oh, I missed your, perhaps you should do it

@shep - Step 7 is also optional, perhaps your app need it, but I doubt it

Thanks for the hints VDVsx, Now Wikified: http://wiki.maemo.org/MADDE/Packaging .... feedback appreciated.

What is that service file for then? I pieced this all together from different bits and pieces around the forums.

For advertise/register/link a d-bus service in this case.
