        You're missing some required libraries when building

        [...]
/home/pi/RetroPie-Setup/tmp/build/cgenius/GsKit/graphics/GsTexture.h:5:23: fatal error: SDL_image.h: No such file or directory
[...]

        These dependencies should have been automatically installed by the RetroPie-Setup script (package libsdl2-image-dev), but it seems they're not. Can you install them manually with the command

        sudo apt-get -y install build-essential cmake libcurl4-openssl-dev libvorbis-dev libogg-dev libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libboost-dev python3-dev

        and then retry the installation ?

            Hm, there doesn't seem to be any radical changes recently in the upstream repository. I'll take a look to build it myself, but just to eliminate any corruption, can you re-install the the SDL deveopment libraries dependencies:

            sudo apt-get -y install --reinstall libsdl2-image-dev libsdl2-mixer-dev

            and then retry building ?

              Thanks so much for the quick responses, still giving me the same build error though, noticed I also have issues trying to build Abuse

              Edit: seems to work on my Pi Zero W fine

              Edit 2: not sure if this helps but here is my abuse build log https://paste.ee/p/uRqtq

                I tried building CGenius and I don't get any errors building - in the same step you're having the error. Looking over the CMake output, I see that on my system I have SDL detected in the system's folder

                [..]
-- Found Threads: TRUE
-- Found SDL2: /usr/lib/arm-linux-gnueabihf/libSDL2main.a;/usr/lib/arm-linux-gnueabihf/libSDL2.so;-lpthread
[...]

                while in your log it's detected in the local site folder

                -- Found Threads: TRUE  
-- Found SDL2: /usr/local/lib/libSDL2main.a;/usr/local/lib/libSDL2.so;-lpthread

                while the rest of the SDL2 libraries (mixer, image) are in the system folders (/usr/lib/arm-linux-gnueabihf/). This SDL installation mismatch is probably what's causing the compilation to fail.

                Did you install manually SDL2 into your system ? What image have you used to install RetroPie ?

                  I did not install SDL manually but I did install retropie manually over raspbian stretch, I built it back in march when there wasn't yet a compatible image for the 3B+. Is there a way to resolve this mismatch?

                    I can't give any advice on how to get it removed since I don't know how it got there and how it was installed, plus there might be other software that depends on it (especially if it was built from source).

                      so best bet is to backup my files and reimage?

                        Probably yes.

                            is the current posted retropie 4.4 image compatible with 3B+ or should I just reinstall from scratch?
