Installing Qt and PySide on Angstrom

I tryed to install PySide for interface development in Qt. I got it to work on my Arch box, but after several attempts to install it on Angstrom running on a BeagleBone Black rev. A5

Using various means for installation, such as:

easy_install pyside
pip install pyside 

and building it from source.

Everytime i attempt to install i receive the same output

As can be seen it has difficulties locating Qt4, which I have installed using:

 opkg install qt4-embedded
 opkg install qt4-tools

Answers


So i found the solution to the problem.

Purging Qt and reinstall using with the following did the trick:

 opkg update #always a good idea
 opkg install qt4-x11-free-dev 

Furthermore the following must be installed as well

 opkg install libxslt-dev
 opkg install libqtxml-dev
 opkg install libqtcore-dev 
 opkg install libqtgui-dev

Finally:

 opkg install python-pip python-setuptools python-smbus
 pip install pyside

And now we can start programming.
