Analog widgets for embedded device problem

thehilmisu · wrote on 22 Mar 2012, 10:22

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 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:

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.
