Qt Everywhere Opensource on Ubuntu 10.04

[davidsp]

Hi,

After losing faith in Fedora I moved over to Ubuntu but have hit another stumbling block whilst trying to get QT4.7.4 running -

I'm trying to build with phonon included as so

bq. ./configure -v -embedded arm -xplatform qws/linux-arm-imx -phonon -force-pkg-config

This gives;

bq. ...

Phonon support cannot be enabled due to functionality tests!
Turn on verbose messaging (-v) to ./configure to see the final report.
If you believe this message is in error you may use the continue
switch (-continue) to ./configure to continue.

If I do not include Phonon then the build succeeds. I think I have all the packages I require, looking through my package manager everything appears to be there.

As you can tell I'm new to Linux and QT, any help would be greatly appreciated.

Since you're cross compiling, are you sure you have everything (that phonon needs) provided by your toolchain? I can see that glib is missing, and IIRC that's required by the gstreamer backend.

Hi peppe,

I ran

bq. apt-get install glib*

And everything installed on the glib side. I still get the same error when trying to configure Qt.

edit: I have looked through the requirements here http://doc.qt.nokia.com/stable/requirements-x11.html#phonon-dependencies and attempted to install all the required packages. A few would not install due to unmet dependencies but I'm not sure how to remove those conflicts?

You must install those libraries for the embedded toolchain, not the host one. See if your toolchain ships with those libraries, otherwise recompile them.

Hi again,

Sprry I was not more clear - I was able to configure Qt4.7.4 OS exactly as I have attempted to do here on my previous Fedora based host. I then moved over to an Ubuntu based host and followed the same steps (trying to install any missing packages on the host) but I still have no luck. My target and target toolchain have not changed.
