Re: KDE and SDL2: some problem with syntax analyser

KDevelop 5.2.4 on Fedora 29 installed by dnf command.

When file SDL_surface.h is open in the view "problem" there is only one
warning row :

"Problem in Preprocessor
Header is not guarded against multiple inclusions

The given header is not guarded against multiple inclusions, either with
the conventional #ifndef/#define/#endif macro guards or with #pragma once."

No problem on file SDL.h

Do you think it could be a kdevelop version problem? in this case I have
to work on a virtual machine (tomorrow I'll try this solution) or wait
for next update..
