== SIP4-TQT ==
[[En/trinity_desktop_environment#Base_Packages]]
SIP is a tool written to ease the creation of bindings between the Python language and libraries written in the C or C++ programming languages. SIP was originally meant to create '''PyQt''', Python bindings for the QT toolkit, but '''can be used with every library written in C or C++'''. Slackware contains an official SIP package which '''lacks compatibility with the TQT libraries''' needed by the '''Trinity Desktop Environment''' to properly work. All TDE related Python packages require SIP to build and run once installed. As a consequence a custom TDE version of SIP is needed to replace the Slackware included one.
=== Sip4-tqt and Slackware ===
Source code for the custom SIP version: '''sip4-tqt''', is not released as a tgz archive along the other desktop environment packages. The code can be retrieved from the project [http://git.trinitydesktop.org GIT repository] only. Two ways exist to download it:
* Connect to the repository through a web browser and download a compressed archive of the last available version of the ''master'' branch. [http://git.trinitydesktop.org/cgit/sip4-tqt/snapshot/sip4-tqt-master.tar.gz sip4-tqt-master.tar.gz]
* Install GIT on your machine and use the following commands:
:# Move in the directory You wish to download the files to
:# Run command '''git''' ''clone'' http://anonymous@scm.trinitydesktop.org/scm/git/sip4-tqt
:# Rename the root source code directory: '''mv''' sip4-tqt sip4-tqt-master (This is only needed to copy with the naming convention of the file downloaded with the previously described method)
:# Build an archive of the source code files: '''tar''' ''-zcf'' sip4-tqt-master.tar.gz sip4-tqt-master
Whatever the method, we will use the resulting sip4-tqt-master.tar.gz file to build a working SIP package as described further below.
Being an official package, a SlaclBuild script exists and can be used as a reference for the packaging procedure. The customized package will replace the standard one and as such '''/opt/trinity''' cannot be used as root directory. We will instead use '''/usr''', the predefined SIP installation directory. The official package '''does not use autotools nor [http://www.cmake.org/ cmake] for configuring''', only a Phyton script: '''configure.py''', which can be executed running: '''python''' configure.py <options> . Once configured the package can be built running '''make''' followed by '''make''' ''install''.
My first attempts at compiling SIP failed due to some missing include files issues resulting in compiler errors. From reading the TDE documentation I learned the command line was in need of some additional paths were to search for include files. Adding those paths only resolved one of the three errors the make command returned. The remaining two errors were solved by adding some links to directories. In short:
Run command:
'''export''' SLKCFLAGS="-O2 -march=i486 -mtune=i686 '''-I/usr/include/tqt'''"
'''export''' PYTHONVER=$(python -V 2>&1 | cut -f 2 -d' ' | cut -f 1-2 -d.)
'''export''' PYTHONLIB=$( python -c 'from distutils.sysconfig import get_python_lib; print get_python_lib()' )
'''python''' configure.py \
-b "/usr/bin" \
-d "$PYTHONLIB" \
-e "/usr/include/python$PYTHONVER" \
CFLAGS="$SLKCFLAGS" \
CXXFLAGS="$SLKCFLAGS"
to configure sip-tqt for a 32 bit environment.
Passing option '''-I/usr/include/tqt''' to the configuration script is mandatory to solve the following error:
bash-4.2# '''make'''
make[1]: Entering directory `/usr/src/tde/3.5.13.2/sip4-tqt/sip4-tqt-3.5.13.2/sipgen'

Create link:
'''ln''' ''-s'' /usr/include/tqt /usr/include/tqt4
To solve another compiler error:

To solve error:

gcc -c -O2 -march=i486 -mtune=i686 -I/usr/include/tqt -O2 -w -DNDEBUG -I. -o main.o main.c

make[1]: Leaving directory `/usr/src/tde/3.5.13.2/sip4-tqt/sip4-tqt-3.5.13.2/sipgen'
make: *** [all] Error 2
Adding include files to the configure.py command line was not enough to solve all three errors, therefore the need for links.
A SlackBuild script including all of the instructions and hacks needed to build can be downloaded from the following [http://www.giustetti.net/resource/slackbuild/tde/35132/sip4-tqt.tar.gz link]. The '''tde''' suffix was added to the package name in order to differentiate it from the standard one.
After packaging SIP, before installing it please remember to remove the Slackware package running command:
'''removepkg''' sip-4.13.2-i486-2
Then command:
'''installpkg''' sip-tde-i486-1sg.txz
Otherwise You can replace the two command sequence with a single upgradepkg:
'''upgradepkg''' sip-4.13.2-i486-2'''%'''sip-tde-i486-1sg.txz
After installing sip-tqt You can go on with building the other TDE Python packages.
