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 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 qt-platform-mkspecs git (look for folder "4.7/qws/linux-97420c0-mipsel-uclibc-g++") and copy it in newly created folder in

above 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

3 Invoke qmake on the applications .pro file

$ qmake <application>.pro

4 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"

Note - after copying, the path should appear as "/usr/local/qt-installs/qt-dfb-97420C0-rel"

2 Copy the application binary and other required resource files on target file-system, at say "/root"

3 On target, goto directory containing directfb startup script as,

# cd /usr/local/bin/directfb/1.4

4 Install board specific modules and create device nodes by running "rundfb.sh" as,

# ./rundfb.sh install

5 Launch application using same rundfb.sh script as,

# ./rundfb.sh /root/app1/app1 -qws -display directfb
