| - | | + | |
| - | ==maemo-select-menu-location: command not found==
| + | |
| - |
| + | |
| - | '''Typical error message'''
| + | |
| - | scratchbox/tools/bin/sh: line 1: /usr/sbin/dpkg-preconfigure: No such file or directory
| + | |
| - | Setting up leafpad (0.8.16le-0maemo2) ...
| + | |
| - | gtk-update-icon-cache: Cache file created successfully.
| + | |
| - | /var/lib/dpkg/info/leafpad.postinst: line 7: maemo-select-menu-location: command not found
| + | |
| - | dpkg: error processing leafpad (--configure): subprocess post-installation script returned error exit status 127
| + | |
| - | | + | |
| - | '''Reason'''
| + | |
| - | | + | |
| - | maemo-select-menu-location is obsolete.
| + | |
| - | In Fremantle, there is no submenu like, "Utility", "Extra", "Settings" etc. All installed 3rd party software will be visible under "Applications" by default.
| + | |
| - | | + | |
| - | '''Action'''
| + | |
| - | Remove the instance from the post installation script. It is not needed.
| + | |
| - | | + | |
| - | | + | |
| - | ==Missing dependency: maemo-installer-utils==
| + | |
| - | '''Reason'''
| + | |
| - | | + | |
| - | The package hildon-application-manager no longer "provides" ''maemo-installer-utils''. The commands ''maemo-confirm-text'', ''maemo-application-running'', ''maemo-list-user-packages'' are still available.
| + | |
| - | | + | |
| - | '''Action'''
| + | |
| - | | + | |
| - | Replace the dependency with hildon-application-manager.
| + | |
| - | | + | |
| - | | + | |
| - | ==Missing dependency: libhildonhelp0==
| + | |
| - | '''Reason'''
| + | |
| - | | + | |
| - | libhildonhelp is dropped.
| + | |
| - | | + | |
| - | '''Action'''
| + | |
| - | | + | |
| - | Remove the dependency and calls to the help APIs.
| + | |
| - | | + | |
| - | | + | |
| - | ==Limitation of Home Area applets==
| + | |
| - | Unlike Diablo in Fremantle these applets don't support text input, pannable areas, resizing nor scrolling.
| + | |
| - | | + | |
| - | '''Reason'''
| + | |
| - | | + | |
| - | Framework limitations.
| + | |
| - | | + | |
| - | '''Action'''
| + | |
| - | | + | |
| - | Replace text input fields with dialogs. Use buttons for scrolling. Add resizing options in the settings dialog or adapt the UI of the applet regarding to that. For further information on how to develop those applets, please check the [http://wiki.maemo.org/Documentation/Maemo_5_Developer_Guide/Application_Development/Writing_Desktop_Widgets documentation].

| - | ==What icon size should be used?==
| + | |
| - | With Fremantle the size specifications of the icons are different from Diablo:
| + | |
| - | | + | |
| - | '''Application Manager'''
| + | |
| - | * Icon size: HILDON_ICON_SIZE_FINGER.
| + | |
| - | * In Gimp or Photoshop: 48x48 pixels
| + | |
| - | | + | |
| - | '''Task Launcher'''
| + | |
| - | * Icon size: HILDON_ICON_SIZE_THUMB.
| + | |
| - | * In Gimp or Photoshop: 64x64 pixels
| + | |
| - | | + | |
| - | ==Initialisation scripts==
| + | |
| - | | + | |
| - | '''Problem'''
| + | |
| - | | + | |
| - | Initialisation scripts don't work any more.
| + | |
| - | | + | |
| - | '''Reason'''
| + | |
| - | | + | |
| - | Fremantle has switched to using '''upstart''' for system initialisation.
| + | |
| - | | + | |
| - | '''Action'''
| + | |
| - | | + | |
| - | Create '''upstart''' job definitions instead of init scripts. Information on writing these can be found on http://upstart.ubuntu.com/getting-started.html. However, be aware that the directory used on Maemo 5 is ''/etc/event.d''.
| + | |
| - | | + | |
| - | The job script should be placed in /etc/event,d/''package''. And the package postinst, prerm and postrm should use the ''start --quiet'' and ''stop --quiet'' commands to start and stop the service. Unfortunately there is no debhelper tool to assist with this.

| - | == What can I do if my question is not mentioned here? ==
| + | |
| - | | + | |
| - | # Look if it is discussed already in one of the mailing lists or in [http://talk.maemo.org talk.maemo.org]
| + | |
| - | # If not post your question in the developer mailing list or in talk
| + | |
| - | # If you find the answer and you think it could be interesting for others as well post it here, so that we just have to point on this page in the future if the question pops up again.
