This article may require cleanup to meet the Qt Wiki's quality standards. Reason: Auto-imported from ExpressionEngine.
Please improve this article if you can. Remove the {{cleanup}} tag and add this page to Updated pages list after it's clean.

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 eglfs / QPA

  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/qpa
  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 ' for example, $ 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-eglfs.patch" to eglfs Qt Lighthouse Driver located at <qt-4.8.0-sources>/src/plugins/platforms/eglfs

' $ cd <qt-4.8.0-sources>/src/plugins/platforms/eglfs ' $ patch -p4 < 7425nxs-eglfs.patch

  1. Configure Qt as,

' $ configure -qpa -arch mips -xplatform qpa/linux-nxs-mipsel-uclibc-g+ -depths 16,24,32 -no-largefile -no-accessibility * -opensource -verbose -system-zlib -system-libpng -system-libjpeg -system-freetype -fast -opengl -webkit -confirm-license * -release -make libs -xmlpatterns -exceptions -no-qt3support -prefix /usr/local/qt-installs/qt480ga-nxs-qpa-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-qpa-rel ' PATH=/usr/local/qt-installs/qt480ga-nxs-qpa-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-qpa-rel" is copied on target file system at "/usr/local"

' Note- after copying, the path should appear as "/usr/local/qt-installs/qt480ga-nxs-qpa-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 -platform eglfs

NOTE: Before executing any Qt applications on target copy "qt-installs/qt480ga-nxs-qpa-rel" on target at usr/local on target file system
