Building AppLibs/RefSW for Qt

  1. Locate document named "BroadcomReferencePlatformSetup.pdf" (Usually this will be inside a tar ball named on the lines of refsw_release_<chip-name><date>.tgz)
  2. Follow the instructions in "BroadcomReferencePlatformSetup.pdf" to setup the Linux build machine
  3. Locate document named "AppLibsInstallationBuildGuide.pdf" (Usually this will be inside a tar ball named on the lines of applibs_release<date>.tgz)
  4. Follow the instructions in "AppLibsInstallationBuildGuide.pdf" to build Applibs

Qt 4.8 eglnullws / QWS

This details steps to build Qt with Qt's OpenGL graphics driver.
This OpenGL graphics driver supports execution of Single Qt app that uses QGLWidget as full-screen (examples/opengl/hello_gles2)

  1. Obtain qt-4.8.0 release from Qt Download site and extract it in a working folder
  2. Obtain 7425 specific files from qt-platform-mkspecs git (look for folder "4.8")
  3. Copy folder named "linux-7425nxs-mipsel-uclibc-g+" to <qt-4.8.0-sources>/mkspecs/qws
  4. Set following environment variables in the shell before configuring/building Qt,

' BCM_APPLIBS_PATH=<path-till-Applibs-folder>/AppLibs ' BCM_NEXUS_PATH=<path-till-Applibs-folder>/nexus ' DEBUG=n

$ export BCM_APPLIBS_PATH=/home/qtnokia/WorkDir/97425-P1/stb-rs_p2-al_p2dot1/AppLibs
$ export BCM_NEXUS_PATH=/home/qtnokia/WorkDir/97425-P1/stb-rs_p2-al_p2dot1/nexus
  1. Apply patch "7425nxs-eglnullws.patch" to eglnullws Qt GFX Driver located at <qt-4.8.0-sources>/src/plugins/gfxdrivers/eglnullws
$ cd <qt-4.8.0-sources>/src/plugins/gfxdrivers/eglnullws
$ patch -p5 < 7425nxs-eglnullws.patch
  1. Configure Qt as,
$ configure -embedded mips -xplatform qws/linux-7425nxs-mipsel-uclibc-g''+ -depths 16,24,32 -no-largefile -no-accessibility -opensource -verbose -system-zlib -system-libpng -system-libjpeg -system-freetype -fast -plugin-gfx-eglnullws -qt-gfx-vnc -opengl -webkit -confirm-license -release -make libs -xmlpatterns -exceptions -no-qt3support -prefix /usr/local/qt-installs/qt480ga-nxs-qws-rel
  1. Build Qt as,
$ make
  1. Install Qt on host as,
$ make install


Building Qt apps

  1. After the Qt build succeeds, set following environment variables on host before building any fullscreen OpenGL Qt App for the above build,

' QTDIR=/usr/local/qt-installs/qt480ga-nxs-qws-rel ' PATH=/usr/local/qt-installs/qt480ga-nxs-qws-rel/bin:$PATH

  1. Ensure that following environment variables in the shell are set,

' BCM_APPLIBS_PATH=<path-till-Applibs-folder>/AppLibs ' BCM_NEXUS_PATH=<path-till-Applibs-folder>/nexus ' BCM_TARGET_LIBDIR=<path-till-nfsrootfs-base-folder>/romfs/lib ' DEBUG=n

  1. Invoke qmake on the applications .pro file (<qt-4.8.0-sources>/examples/opengl/hello_gles2)
$ qmake <application>.pro
  1. Build the application sources as,
$ make

Running Qt apps on target

  1. Ensure that folder "qt-installs/qt480ga-nxs-qws-rel" is copied on target file system at "/usr/local"

' Note- after copying, the path should appear as "/usr/local/qt-installs/qt480ga-nxs-qws-rel"

  1. Copy the application binary and other required resource files on target file-system, say "/root"
  2. Locate a shell script named "start" in "/bin" folder on target.
  3. Copy it in your app folder and edit the paths inside it.
  4. Launch application using same "start" script as,
# ./start /root/app1/app1 -qws -display eglnullws
