How to package my app. that can automatically install other necessary app. or lib

[hpbrother]

How to package a .deb file that can automatically install the libraries or components which are included in the main program, that is, the codes can check libraries in the phone and install the necessary one or ones?

ex : My application are based on "mbarcode"(it can install by N900's app manager), how do I packing my application that can automatically install the "mbarcode" or some necessary lib?

[achipa]

You need to specify the dependant library in the debian/control file:

Package: mypythonapp
Architecture: any
Depends: python2.5
Description: Short desc
  Detailed desc
  that spans
  multiple lines

Note that the Ovi store does not accept packages with external dependencies for Maemo, you can only submit those to the community repository.

Add to the Source section of debian/control dependency to the library
Build-Depends: your_library-dev

[achipa]

Build-Depends is something different - it is related only to the compile/bulid part of the app's life cycle - just in itself it will not guarantee what the OP wants - the installation of missing libs/components on the device (unless you pair it with shlibs, but that's a different story).

pscreate template has ${shlibs:Depends} macro specifically to ensure that nothing like that is needed. The only thing what is required from developer is to fill Build-Depends: properly.

[achipa]

No. As I said, shlibs is a different story. It will NOT guarantee the inclusion of all packages you want it to depend on, only ones you directly link to or add (a subtle, but distinct difference, especially important if the packages you want to depend on are modules/plugins or simply not libraries). Additionally, the OP did not specify what tooling he is using (Nokia Qt SDK or Maemo 5 SDK).

[hpbrother]

Add Build-Depends

Package: myapp

Priority: optional
Version: 1.0.0
Architecture: all
Maintainer: myapp <myapp@gmail.edu.tw>
Build-Depends: libzbar-dev
Depends: libzbar-dev

But it return an warning messasge

[sbox-FREMANTLE_ARMEL: ~] > dpkg -b myapp
warning, 'myapp/DEBIAN/control' contains user-defined field 'Build-Depends'
dpkg-deb: building package 'myapp' in 'myapp.deb'
dpkg-deb: ignoring 1 warnings about the control file(s)

It still build a .deb file but it still can not automatically install other lib

It was already 300 times said that you don't use dpkg -b to produce the package, but use only
dpkg-buildpackage -i -rfakeroot -D
http://wiki.forum.nokia.com/index.ph...Source_Package

[hpbrother]

I have try dpkg-buildpackage -i -rfakeroot -D to package the .deb file,
but when I install it to N900 it still just tell me "Application packages missing: libqtm-systeminfo".

It still can not install libqtm-systeminfo automatically .

PS: In this case ,my app have use some qt-mobility api. When I install my application I want it can automatically install qt-mobility api(libqtm-systeminfo).

This is my debian/control file:

but when I install it to N900 it still just tell me "Application packages missing: libqtm-systeminfo".

Debian (and Maemo) has 2 installation tools. dpkg - low level utility installing local Debian packages and apt - high level utility for installation of Debian packages from Debian repository. dpkg is not installing depenencies needed for your application. apt, however, does.

You can solve your case by running two sequential commands:

apt-get install libqtm-*
dpkg -i myapp_0.0.1_armel.deb

It still can not install libqtm-systeminfo automatically.

You would need to place your Debian package into any Debian repository and possibly configure apt on the device to use it, if not already.

Could you also describe what are you trying to achieve in general?

[hpbrother]

After packing my app. I put it on the web. If I want to install the app. I just open N900's browser and go to the website (ex: http://xxxx/myapp.deb). Then the app. can install to my N900.

But my new application have used Qt-Moblity-API. If I want to install my new app. on N900. I have to install qt-mobility-example from N900's "app. manager" before my new application.

Now I want to package my new app. that If open the N900's browser and go to the my application's website. It can automatically install Qt-Mobility-API before my new application.

If I want to do this What should I do???

If uploading to Extras-devel repository is not an option for you, you can create your own Debian repository containing your package.
http://www.debian.org/doc/manuals/re...pository-howto
Then you can install package by opening .install file in Maemo Web Browser
