    Default Problem with installing Qt on XP

    Hello

    Last two (almost 3) days I spent in setting up Qt on an old XP laptop. What I did was
    a. with mingw-get install mingw/msys
    b. downloading the open source version of qt for windows (4.7.3)
    While downloading there was a complaint that some api.h was too new for Qt, I decided to continue
    c. I modified the XP Path variable by proper entries to mingw/bin and Qt\4.7.4\bin
    d. I reconfigured and compiled libraries for portaudio, libsndfile, libsamplerate, fftw3, libusb, libftdi and, last but not least qwt-5.2.2 (my sdr application uses there)

    Finally, I was able to run qmake and make on my application (that runs perfectly under Xindows-7 and Linux (Ubuntu and Fedora).

    However, make complains that the references to "alloca (unsigned int)" cannot be resolved.

    When running an arbitrary smll program with an alloca in it, there is no problem, so it probably has to do with a wrong or incomplete setting of some library paths.

    a. How do I find which libraries - not the one I explicitly give - are searched
    b. How can I teach qmake to take these into account?
    c. any clue which library contains "alloca"

    thanks for any help

    Solved,

    this particular problem was MINGW related and someone there pointed out how to address it.
