h1. Building AppLibs/RefSW for Qt

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

Qt 4.8 DirectFB / QWS

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&quot;)
3. Copy folder named "linux-7425dfb-mipsel-uclibc-g+" to <qt-4.8.0-sources&gt;/mkspecs/qws
   # Set following environment variables in the shell before configuring/building Qt
   ' BCM_APPLIBS_PATH=<path-till-Applibs-folder&gt;/AppLibs
   ' BCM_NEXUS_PATH=<path-till-Applibs-folder&gt;/nexus

h1. 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&gt;/AppLibs
' BCM_NEXUS_PATH=<path-till-Applibs-folder&gt;/nexus
' BCM_TARGET_LIBDIR=<path-till-nfsrootfs-base-folder&gt;/romfs/lib
' DEBUG=n
# Invoke qmake on the applications .pro file

<br />$ qmake &lt;application&amp;gt;.pro<br />

# Build the application sources as,

<br />$ make<br />

h1. Running Qt apps on target
# Ensure that folder "qt-installs/qt480ga-mdfb-rel&quot; is copied on target file system at "/usr/local&quot;
' Note after copying, the path should appear as "/usr/local/qt-installs/qt480ga-mdfb-rel&quot;

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

   # cd /usr/local/bin/directfb/1.4<br />
   

3. Install board specific modules and create device nodes by running "rundfb.sh&quot; as,
   

   # ./rundfb.sh install<br />
   

4. Launch application using same rundfb.sh script as,
   
5. ./rundfb.sh /root/app1/app1 -qws -display directfb
