    Hi

     

    Application built quite ok, but when running, most of the graphics doesnt appears

    in console output I’ve got:

     

    file:///home/vladest/FelgoSDK/Demos/FelgoSDK/CarChallenge-build-desktop-Desktop_Qt_4_8_1_for_GCC__Qt_SDK__Debug/qml/Level.qml:32:5: QML Image: Error decoding: file:///home/vladest/FelgoSDK/Demos/FelgoSDK/CarChallenge-build-desktop-Desktop_Qt_4_8_1_for_GCC__Qt_SDK__Debug/qml/img/playground.jpg: Unsupported image format

    etc

    I’ve got

    libpng12.so.0 => /lib/x86_64-linux-gnu/libpng12.so.0 (0x00007fc698c28000)

     

    which is weird, because I’ve added to the projectinclude.pri file:

    LIBS += $$THIRDPARTY_LIBRARY_PATH/libpng.a

    which should compile your statically built libpng 1.4

     

    can you help me with this?

     

    Thanks

    Hi,

    thanks for pointing this out! Our development team is currently only testing (and officially supporting) 32- or 64-bit Linux Ubuntu 12.04 and 12.10. We however got our demo games (and therefore all other Felgo powered games) running on 13.04 too by adding the following line right after including the third-party libraries in the corresponding project file:

    LIBS += -lpng12 -lz -lfontconfig

    You may need to install additional packages in case the linker fails:

    sudo apt-get install libfontconfig1-dev libpng12-dev

    Please keep us updated if this works out for your development environment too. We will then add 13.04 support to our next stable release.

    Thanks,

    Alex
