Are you saying that mad-admin xdpkg does not install the shlibs file
into the sysroot? That sounds like a bug to me.
Anyway, could it be that the shlibs file is somehow not containing the
correct information? Have you checked its contents and compared with
what the man page for deb-shlibs says?

The reason is that that such an old MADDE does not support checking those
dependencies in xdpkg -installed packages:

$ git log patches/dpkg-1.14.25.diff | head -7
commit 7607722394ea331ed887e4b5e2e50d29271f9cd8
Author: Pasi S...
Date: Mon Apr 18 13:14:38 2011 +0300

added xdpkg extended package support for dpkg-shlibdebs.

commit 907858016b35160a395b00caee854450b1dade2c

... In addition to Pasi's above patch I made some changes to xdpkg.pl,
which is available in

https://meego.gitorious.org/meego-developer-tools/madde/blobs/master/src/madlib/xdpkg.pl

As re-creating dpkg-shlibs is somewhat less trivial I'll include newer
version as a gzipped attachment of this email.


So, in order to test whether these changed dpkg tools fix the problem you
need to 'taint' your madde installation, first do:

$ mad-admin xdpkg --list

$ for p in <xdpkg-installed-packages>; do mad-admin xdpkg --purge $p; done

$ maddir=/home/talmage/QtSDK-1.1/Maemo/4.6.2/

$ find $maddir/madlib -name '*xdpkg*'

$ mkdir $maddir/backup
$ mv /path/to/found/*xdpkg* $maddir/backup
$ mv $maddir/madbin/dpkg-shlibdeps $maddir/backup
$ cp /path/to/xdpkg.pl /path/to/found/*xdpkg*
$ cp /path/to/dpkg-shlibdeps $maddir/madbin

And check if things work; if not, just rename files from
$maddir/backup back to their original locations.

Yes, the version of mad-admin I had did not install the shlibs file into the
sysroot.

According to the deb-shlibs man page, libqcontactchooserdialog.shlibs should
look like this:

libqcontactchooserdialog 1 libqcontactchooserdialog (>= 1.0-0)


Instead, mine looks like this:

libqcontactchooserdialog 1 libqcontactchooserdialog


In other words, it's missing the version number in the dependencies field.

After I followed Tomi's directions, I have
$SYSROOT/madde_xpkgs/libqcontactchooserdialog.shlibs. This is new, I think.

There isn't one in $SYSROOT/var/lib/dpkg/info.

Tomi, the new dpkg-shlibdeps and xdpkg files didn't fix the problem. I get the
same output as before when deploying my application.

Could this be related to the location of my library? It's in
$SYSROOT/opt/usr/lib instead of $SYSROOT/usr/lib.

I corrected that in $SYSROOT/madde_xpkgs/libqcontactchooserdialog.shlibs. It
didn't make a difference.

I've discovered that dpkg-shlibdeps forks

/home/talmage/QtSDK-1.1/Maemo/4.6.2/bin/mad dpkg --search
/home/talmage/QtSDK-1.1/Maemo/4.6.2/sysroots/fremantle-arm-
sysroot-20.2010.36-2-slim/opt/usr/lib/libqcontactchooserdialog.so.1


and the search fails. Madde's dpkg is looking only in
$SYSROOT/var/lib/dpkg/info for the .shlibs files.


I discovered two more things.

1. the version of dpkg at meego.gitorious.org *does* look in
$SYSROOT/madde_xpkgs.
2. So does the version of dpkg in QtSDK-1.1/Madde/madbin.


This is very interesting. I reverted libqcontactchooserdialog.shlibs to its
original form and replaced /home/talmage/QtSDK-1.1/Maemo/4.6.2/bin/madbin/dpkg
with the one from QtSDK-1.1/Madde/madbin. I can build the application package
now!

Thanks to Tomi and Christian for their advice. It made me look in the right
places. I am very happy to be able to resume development!

Dave

Thanks for digging a bit deeper. I missed that 'dpkg' had related
changes and therefore an updated version of dpkg was needed as well.
Your approach to "fix" this problem was the right one!
