Analog widgets for embedded device problem



  • Hi everyone,
    i want to build an analog speedometer for my embedded device, and i found this http://qt-apps.org/content/show.php/AnalogWidgets?content=87780.

    I build it with my ubuntu computer and it works fine, but when i changed the build configuration to my arm processor embedded device, i get plenty of this error @qmake.conf:21: error: Using OS scope before setting MAKEFILE_GENERATOR@

    Is there anything that i could make it work this on my my device ? or if you have a suggestion for how to build a speedometer with qt? i would listen to it because i dont know what can i do..



  • Hi thehilmisu,

    is this a problem with the spedometer, or did you never compile Qt projects for arm before?

    Do you have a Qt version that is compiled for your embedded device? If not, you have to build it from scratch, which means, get the source tar ball and call configure / make for the platform with the correct parameters. Then you must use this Qt for the arm build.

    i've compiled Qt projects for arm before. The problem is speedometer project. I can run it on linux desktop but when i select my arm configurations, it is not even build the program



  • Hi
    Personally I have not tested it with arm compiler. But I have few reports that pepole were able to do that on that platform. I belive you should check your compilation enviroment. However if you find that there is something that can be fixed in AnalogWidgets. Patch/Fix will be warmly welcomed :).

    i am trying to compile with my angstrom cross compiler, if i can do that i will let you know of course. By the way it's a great job. Those widgets are awesome



  • I get this error, when i try to compile the project,

    @no such instruction: 'swpb %dl,%al,[%esi]'@

    I have searched the error and i found out this is caused by my compiler's configuration. But i could not find any solution.



  • I always get those errors when compiling within Creator, but not when compiling on the command prompt.



  • If you use Creator, you might find more info here:

    yes i am using Creator. how can i compile the project with command line ?



  • Basically, by setting up the environment you need (path, QTDIR, QMAKESPEC), then calling "qmake yourproject.pro" and "make"

    I'm far from being an expert on that matter, though.
