[Qt-creator] src build failed: `gst_element_link_pads_full'

[Bryce Schober]

I was thinking about probing into why some of my projects' source isn't
being correctly understood, and decided to build Qt Creator from source. I
used the reference from
www.qt-project.org/wiki/How_To_Build_Qt_Creator_From_Source. I have the Qt
SDK 4.8 installed, updated to 4.8.1 with sources. I used Qt Creator 2.5.0
final as the IDE to build latest git/master.

I got a warning about not having the QtDeclarative module, so I went ahead
and
defined QT_PRIVATE_HEADERS=/home/bschober/bin/QtSDK-4.8/QtSources/4.8.1/include
even though the wiki suggested that shouldn't be a problem with 4.8.

Then the build proceeded without any module warnings until the link step,
where it failed with:

undefined reference to `gst_element_link_pads_full'

Any pointers about where to go from here?
FWIW, I'm on an Ubuntu 10.04 i686 system w/ an older 4.3.4 gcc.
