Building Qt5 for Embedded Linux -> Problem with OpenGL



  • Good day fellow programmers,
    I am trying to deploy an application to a Raspberry Pi running Debian.
    So far I have been following this guide: http://www.ics.com/blog/building-qt-5-raspberry-pi#.Uf4cV-F3Q5a
    However I am experiencing problems when it comes to building Qt 5.

    These steps lead to the problem:
    @$ ./configure
    -release
    -opengl es2
    -optimized-qmake
    -no-pch
    -make libs
    -make tools
    -reduce-exports
    -sysroot /mnt/raspberry-rootfs
    -device linux-rasp-pi-g++
    -device-option CROSS_COMPILE=~/raspberry/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-
    -prefix /usr/local/Qt-5.1.0-raspberry
    @

    This is the error output:
    @Could not determine the target architecture!
    Turn on verbose messaging (-v) to see the final report.
    All the OpenGL functionality tests failed!
    You might need to modify the include and library search paths by editing
    QMAKE_INCDIR_OPENGL, QMAKE_LIBDIR_OPENGL and QMAKE_LIBS_OPENGL in
    /home/parallels/qt-everywhere-opensource-src-5.1.0/qtbase/mkspecs/devices/linux-rasp-pi-g++.
    @

    Does anyone has an idea to solve this issue?
    Any help wpuld be greatly appreciated!

    Thanks a lot!

  • Confirm if following paths exist on your development machine

    /mnt/raspberry-rootfs/opt/vc/lib
    /mnt/raspberry-rootfs/opt/vc/include
    /mnt/raspberry-rootfs/opt/vc/include/interface/vcos
    /mnt/raspberry-rootfs/opt/vc/include/interface/vmcs_host
