Compiling Qt everywhere libraries 4.8.3 stops at "floatmath auto-detection... ()"



  • Hi

    I am trying to compile the Qt everywhere libraries 4.8.3 for Embedded linux but am stuck in the configure with no error message or anything. I'm running ubuntu 12.10 and I have installed all the required libs from "here":http://qt-project.org/doc/qt-4.8/requirements-x11.html

    During configure it's able to compile and link qmake, but simply stalls at "floatmath auto-detection... ()" and never gets any further.
    Has anyone seen this problem before?

    Oh, and it reacts the same if I configure with no flags.

    @$ ./configure -embedded arm -xplatform qws/linux-arm-g++ -qt-kbd-linuxinput -qt-mouse-tslib -continue -opensource -verbose -R /home/john/apps/tslib_arm/lib/

    Determining system architecture... (Linux:3.5.0-18-generic:x86_64)
    64-bit AMD 80x86 (x86_64)
    'arm' is supported
    'x86_64' is supported
    System architecture: 'arm'
    Host architecture: 'x86_64'

    You have not explicitly asked to use pkg-config and are cross-compiling.
    pkg-config will not be used to automatically query cflag/lib parameters for
    dependencies

    Precompiled-headers support enabled.
    Symbol visibility control enabled.

    This is the Qt for Embedded Linux Open Source Edition.

  • Are you using the proper compiler? If you want to compile for ARM, you need a proper compiler, and compiler flags. Do you have the proper flags on the files under qws/linux-arm-g++ ?



  • Yeah, Im using the arm-angstrom-linux-gnueabi compiler and have edited the qws config. I have no idea why this doesn't work. I tried installing ubuntu through VMware on another computer and installed all the same libs, and it compiled fine.

    What would be the reason for stalling at floatmath detection?
