    Hello Guys,

    I’m having problems trying to run the Demo projects, they don’t build. This is my configuration

    Fedora 18 x86_64

    gcc 4.7.2

    I used the default configuration to install the SDK so I’m using the Qt that was downloaded, when I try to build this is the output.


    09:28:18: Running build steps for project ChickenOutbreak…

    09:28:18: Configuration unchanged, skipping qmake step.

    09:28:18: Starting: “/usr/bin/make” -w

    make: Entering directory `/home/arkan/workspace/FelgoSDK/Demos/FelgoSDK/ChickenOutbreak’

    g++-4.6 -c -pipe -O2 -Wall -W -D_REENTRANT -DPLATFORM_LINUX -DQT_NO_DEBUG -DQT_DECLARATIVE_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I../../../Desktop/Qt/4.8.1/gcc/mkspecs/linux-g++ -I. -I../../../Desktop/Qt/4.8.1/gcc/include/QtCore -I../../../Desktop/Qt/4.8.1/gcc/include/QtGui -I../../../Desktop/Qt/4.8.1/gcc/include/QtDeclarative -I../../../Desktop/Qt/4.8.1/gcc/include -I../../../Desktop/FelgoSDK/include -I../shared/qmlapplicationviewer -I. -o main.o main.cpp

    make: g++-4.6: Command not found

    make: *** [main.o] Error 127

    so I changed the gcc version from the project configuration and I got some problems related to missing libraries, then I added them

    LIBS += -lz -lpng -lfontconfig

    Now the problem that I don’t know how to solve is

    `.text._ZN12FpsQMLViewerD2Ev' referenced in section `.text._ZN12FpsQMLViewerD1Ev[_ZN12FpsQMLViewerD1Ev]' of /home/arkan/workspace/FelgoSDK/Desktop/Qt/4.8.1/gcc/../../../FelgoSDK/lib/lib64/libVPlay.a(moc_fpsqmlviewer.o): defined in discarded section `.text._ZN12FpsQMLViewerD2Ev[_ZN12FpsQMLViewerD5Ev]' of /home/arkan/workspace/FelgoSDK/Desktop/Qt/4.8.1/gcc/../../../FelgoSDK/lib/lib64/libVPlay.a(moc_fpsqmlviewer.o)


    any idea?

    unfortunately Felgo libraries are only compatible with gcc-4.6, this is the reason why we hard-coded the dependency in the project file. As described in our installation guide ( you therefore have to install the gcc-4.6 suite on your system too.





    Hello again,


    Thank you for the quick answer, I compiled gcc-4.6 and the issue disappeared, however I had to modified my libpng version to use the 1.2 instead of the 1.5, not a big deal, anyway Thank you so much for the help, this is a great product.

    Thanks for the hint Arkan, we’ll check that and add it to our installation guide.
