BCM 7425 - Qt 4.8 - DirectFB /QWS

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

Qt 4.8 DirectFB / QWS

1. Obtain qt-4.8.0 release from "Qt Download site":http://get.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.8.0.tar.gz and extract it in a working folder
2. Obtain 7425 specific files from "qt-platform-mkspecs git":http://gitorious.org/qt-platform-mkspecs (look for folder "4.8")
3. Copy folder named "linux-7425dfb-mipsel-uclibc-g+" to <qt-4.8.0-sources>/mkspecs/qws
   # Set following environment variables in the shell before configuring/building Qt,
   

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

   
   for example,
   

   $ export BCM_APPLIBS_PATH=/home/qtnokia/WorkDir/97425-P1/stb-rs_p2-al_p2dot1/AppLibs<br />$ export BCM_NEXUS_PATH=/home/qtnokia/WorkDir/97425-P1/stb-rs_p2-al_p2dot1/nexus<br />$ export BCM_TARGET_LIBDIR=/opt/nfsroot_uclibc/romfs/lib
   

   
   # Configure Qt as,
   

   $ configure -embedded mips -xplatform qws/linux-7425dfb-mipsel-uclibc-g''+ -depths 16,24,32 -no-largefile -no-accessibility -opensource -verbose -system-zlib -system-libpng -system-libjpeg -system-freetype -fast -qt-gfx-directfb -qt-gfx-vnc -qt-kbd-linuxinput -qt-mouse-linuxinput -webkit -declarative -multimedia -confirm-license -release -make libs -xmlpatterns -exceptions -no-qt3support -no-xvideo -prefix /usr/local/qt-installs/qt480ga-mdfb-rel
   

   
   # Build Qt as,
   

   $ make<code><br /># Install Qt on host as,<br />
   

   $ make install

h2. Building Qt apps

# After the Qt build succeeds set following environment variables on host before building any Qt Apps for the above build,
*QTDIR=/usr/local/qt-installs/qt480ga-mdfb-rel
*PATH=/usr/local/qt-installs/qt480ga-mdfb-rel/bin:$PATH
# Ensure that following environment variables in the shell are set,

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

# Invoke qmake on the applications .pro file

$ qmake <application>.pro<code><br /># Build the application sources as,<br />

$ make

h2. Running Qt apps on target
# Ensure that folder "qt-installs/qt480ga-mdfb-rel" is copied on target file system at "/usr/local"
Note- after copying, the path should appear as "/usr/local/qt-installs/qt480ga-mdfb-rel"

1. Copy the application binary and other required resource files on target file-system, at say "/root"
2. On target, goto directory containing directfb startup script as,
   

   # cd /usr/local/bin/directfb/1.4<code>
   # Install board specific modules and create device nodes by running "rundfb.sh" as,<br />
   

   # ./rundfb.sh install
3. Launch application using same rundfb.sh script as,
