4. Compiling QT for embedded with webkit and html5 support for play video content via demo of web browser.

Compiling QT for embedded with webkit and html5 support for play video content via demo of web browser.


  • I'm trying to configure Qt 4.8.1 with these parameters:
    ./configure --prefix=/home/freescale/ltib.iMX/rootfs/ -embedded arm -xplatform qws/linux-g++-mx -release -little-endian -host-little-endian -fontconfig -sm -opensource -confirm-license -multimedia -v -webkit
    I have exported PKG_CONFIG_PATH:
    BASH#> echo $PKG_CONFIG_PATH
    /home/freescale/ltib.iMX/rootfs/usr/lib/pkgconfig
    BASH#> pkg-config --exists glib-2.0 gio-2.0 gstreamer-0.10
    BASH#> echo $?
    0
    BASH#>
    so everything appears to be ok:

    My question is - how to fix this problem?

  • Done by commenting out "no-pkg-config" from configuration files..
    Now - everything compiles right. Finally i've got html5 video (and audio) support.

  • OMG, I was suffering with the same problem after I upgrade the qt to 4.8.1.
    This article is something like an oasis on a huge desert for me.
    Thank you!

  • Yeyo, could you show the pkgconfig file content?
    I have the same error but different toolchain.
    Thank's.

  • pkgconfig is not a file, it is a directory with many *.pc files, which describes many of libraries included into toolchain or OS.

  • Yeyo, I wonder how to command ./configure .... (add "no-pkg-config")

  • Edit "configure", search for line
    @ QT_CONFIG="$QT_CONFIG no-pkg-config"@

    and comment it out.

    Before run ./configure script, remember to export your toolchain's PKG_CONFIG_PATH (typically /$toolchain_patch/usr/lib/pkgconfig"
