cmake mises missing Qsci

[qgib]

Original Redmine Issue: 8710
Affected QGIS version: master
Redmine category:build/install

---

Today's (and already for some time) master spits an error on startup about missing Qsci, but cmake doesn't complain about it. If Qsci is a mandatory dependency, it has to be enforced. If it isn't - parts requiring it shouldn't be compiled.

Gentoo ~AMD64

There's nothing to compile - just the python console depends on @QSci@.

Hi,

Like Jürgen mentions, you currently only need to ensure the Python module is installed (though the C++ lib may become a CMake dependency with the next QGIS version).

I'm not familiar with Gentoo, but it looks like you would just need to install "qscintilla-python":http://packages.gentoo.org/package/dev-python/qscintilla-python ? The C++ lib should be installed as a dependency of the Python module.

Processing is a default plugin, right? If it is so, during compilation time is necessary to check for it's dependencies as it doesn't pass the normal plugin installation routine.

Current situation is not OK, as QGIS is trying to use a component even during ccmake part necessary components weren't located.

There are three options:

1. mark QSci as a mandatory dependency;
2. do not install processing and other parts depending on QSci if it's missing;
3. install but disable per default.

I don't know what for QSci is used and how deep is this integration to tell which of the options should be chosen.

Hello, I had the same problem by opening the console from qgis 2.x under OpenSuSE 12.1
The error message was:

 Konnte Python-Konsole nicht öffnen:
 ...

 ImportError: No module named Qsci

Solution:
I installed the package python-qscintilla, nevertheless there was no dependency for this package by installing qgis.
