    @InsideFPV said in QGCS error for Android:

    target_link_libraries(QGroundControl
    PUBLIC
    -ljpeg
    -lpng
    )

    Yes, you're linking libpng.
    Was libpng found when running cmake?
    Where is libpng for Android located?

      You DID add it already! Just look at your CMakeLists.txt file.
      I repeat the questions you did not answer:
      Was libpng found when running cmake?
      Where is libpng for Android located?

          @InsideFPV If Android NDK does not provide it you will have to build it by yourself from source.

                    You're missing libjpeg library now. Install it.

                              @InsideFPV Maybe you should ask QGCS project? It is not part of Qt...
