Build error with libpng 1.2.x
If inkscape fails to build with the following error:
In file included from /usr/include/libpng12/png.h:474, from sp-image.cpp:44: /usr/include/libpng12/pngconf.h:328: error: expected constructor, destructor, or type conversion before '.' token /usr/include/libpng12/pngconf.h:329: error: '__dont__' does not name a type
You should be able to solve that by simply commenting the two mentioned Lines in
//__pngconf.h__ already includes setjmp.h; //__dont__ include it again.;
Tooltips unreadable with KDE Plasma
Under KDE's system settings go to colors > options and disable "Apply colors to non-QT-applications". Restart Inkscape if was running before the change.
