'''Python-tqt''' is a library which binds TQT, the customized QT toolkit used by the Trinity Desktop Environement, with '''PtQt''': a set of language bindings for Python and the many functions and objects provided by the QT framework. Python-tqt is needed for building a working '''python-trinity''' package needed in turn for adding the Python language to '''tdebindings'''.

The first configuration attempt produced the following error:
The first configuration attempt produced the following error:
/usr/lib/qt/include/qglobal.h.
/usr/lib/qt/include/qglobal.h.
After some research through the project wiki page and reading the '''configure.py''' script and the '''qglobal.h''' file, I noticed some inconsistencies: The script was looking for variables '''TQT_VERSION''' and '''TQT_VERSION_STR''', but '''QT_VERSION''' and '''QT_VERSION_STR''' could instead be found in the file. This is probably a consequence of being forced to install the QT3 toolkit instead of the TQT one as discussed in the QT3 related page. The configuration script line 1128 was updated:

And the script could go on one step more. Sadly another error showed up:

Please note that package '''PyQt-4.9.1-i486-3.txz''' had previously been installed as required by the python-tqt documentation. Removing then reinstalling the package produced no noticeable result to the issue. The '''qglobal.h''' file refers to QT release 4.6, but the Trinity Desktop Environment is built upon release 3 of the toolkit. Updating '''qglobal.h''' lines 47 and 52 as shown below:

Got the script going on some more until hitting on a new error born by the lack of some files:

seeming related to the TQT '''namespace'''. I was not able to find some documentation about the subject int the TDE wiki page as a consequence it was impossible to built the package. '''Tdebindings wile be built without Python support'''.
