Reference Software

  • Phase 5.0 Reference software (refsw_release_97420_20100825.src.tgz)
  • Phase 2.5 and Phase 3.0 of DirectFB 1.4.1
  • Toolchain is stbgcc 4.4.5-1.3 (modified by Broadcom)
  • Linux kernel is stblinux-2.6.31-2.5 (modified by Broadcom)

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 4.7 DirectFB / QWS

  1. Obtain qt-4.7.0 release from [http*//get.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.7.0.tar.gz| Qt Download site] and extract it in a working folder
  2. Create folder named "linux-97420c0-mipsel-uclibc-g+" in <qt-4.7.0-sources>/mkspecs/qws
  3. In file <qt_sources>/src/plugins/gfxdrivers/directfb/qdirectfbpaintengine.cpp, comment out line "surface->SetPorterDuff(surface, DSPD_DST);"
  4. Obtain 7420 specific files namely, qmake.conf and qplatformdefs.h from [http*//gitorious.org/qt-platform-mkspecs| qt-platform-mkspecs git ] (look for folder "4.7/qws/linux-97420c0-mipsel-uclibc-g") and copy it in newly created folder in step 2
  5. Set following environment variables in the shell before configuring/building Qt,
export APPLIBS=<PATH Of Base Working Directory where Reference Software is extracted>/AppLibs
export BCM97420C0_DFB_PATH=$APPLIBS/opensource/directfb/bin/DirectFB-1.4.1_release_build.97420C0/usr/local
export BCM_DEV_PATH=$APPLIBS/opensource
export BCM_DEPLOYED_PATH=$APPLIBS/target/97420c0.mipsel-linux-uclibc.release

6. Configure Qt as,

$configure -embedded mips -xplatform qws/linux-974250c0-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 -webkit -confirm-license -release -make libs -xmlpatterns -exceptions
-no-qt3support -prefix /usr/local/qt-installs/qt-dfb-97420C0-rel

7. Build Qt as,

$ make

8. 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 Qt Apps for the above build,
  • QTDIR=/usr/local/qt-installs/qt-dfb-97420C0-rel
  • PATH=/usr/local/qt-installs/qt-dfb-97420C0-rel/bin*$PATH
  • 2 Ensure that following environment variables in the shell are set,
export APPLIBS=<PATH Of Base Working Directory where Reference Software is extracted>/AppLibs
export BCM97420C0_DFB_PATH=$APPLIBS/opensource/directfb/bin/DirectFB-1.4.1_release_build.97420C0/usr/local
export BCM_DEV_PATH=$APPLIBS/opensource
export BCM_DEPLOYED_PATH=$APPLIBS/target/97420c0.mipsel-linux-uclibc.release

1. Invoke qmake on the applications .pro file

$ qmake <application>.pro

2. Build the application sources as,

$ make

Running Qt apps on target

  1. Ensure that folder "qt-installs/qt-dfb-97420C0-rel" is copied on target file system at "/usr/local"
  2. Note- after copying, the path should appear as "/usr/local/qt-installs/qt-dfb-97420C0-rel"
  3. 2 Copy the application binary and other required resource files on target file-system, at say "/root"
  4. On target, goto directory containing directfb startup script as,
  5. cd /usr/local/bin/directfb/1.4
  6. Install board specific modules and create device nodes by running "rundfb.sh" as,
  7. ./rundfb.sh install
  8. Launch application using same rundfb.sh script as,
  9. ./rundfb.sh /root/app1/app1 -qws -display directfb
