Great, looks promising!
Got it working (starting, loading and playing a project anyway) on Fedora 23.
But I had to remove some libQt* files in the Spriter dist falling back to the ones provided by Fedora.
With Spriter provided libs the console log ends with:
QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled
Segmentation fault (core dumped)
Compiler flag issue? Maybe you can deduct the problem from
http://osxr.org/qt/source/qtbase/src/plugins/platforms/xcb/qxcbintegration.cpp where the message seems to originate from.
Thanks
