I've been trying to build a simple shape plugin for Calligra. Since the tutorial I found (https://techbase.kde.org/Development/Tu ... ake_Plugin) seemed to be somewhat out of date, I simply took the Calligra sources and stripped the music shape plugin down to the bare minimum. I finally got my plugin to be recognized, but when I run my test app, which does

Code: Select all

    qDebug() << KoShapeRegistry::instance()->count();
    qDebug() << KoShapeRegistry::instance()->keys();

it crashes with a segfault. (typeinfo name for MyKoShapePluginFactory is the last the debugger has to offer). I should possibly mention that, differing from the original plugin, I tried to build it with qmake instead of cmake. My understanding is that the

Code: Select all

MyKoShapePluginFactory

is generated essentially by two macro calls in mykoshapefactory.cpp:

Code: Select all

K_PLUGIN_FACTORY(MyKoShapePluginFactory, registerPlugin<MyKoShapePlugin>();)
K_EXPORT_PLUGIN(MyKoShapePluginFactory("calligra_shape_formular"))

(all analogous to the music shape sources, of course)

Does anybody have an idea what I could be doing wrong? Thank you for any help in advance!
