h1. Building AppLibs/RefSW for Qt
- 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) - Follow the instructions in "AppLibsInstallationBuildGuide.pdf" to build Applibs
Qt 4.8 eglfs / QPA
- Obtain qt-4.8.0 release from Qt Download site and extract it in a working folder
- Obtain 7425 specific files from qt-platform-mkspecs git (look for folder "4.8")
- Copy folder named "linux-7425nxs-mipsel-uclibc-g+" to <qt-4.8.0-sources>/mkspecs/qpa
# 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<br />$ 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 />

# Configure Qt as,
<br />$ 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 <s>prefix /usr/local/qt-installs/qt480ga-nxs-qpa-rel<br />

# Install Qt on host as,

h1. Building Qt apps
# 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:$PATH
# Ensure that following environment variables in the shell are set,
' BCM_APPLIBS_PATH=<path-till-Applibs-folder>/AppLibs
' BCM_NEXUS_PATH=<path-till-Applibs-folder>/nexus
' BCM_TARGET_LIBDIR=<path-till-nfsrootfs-base-folder>/romfs/lib
' DEBUG=n
# Invoke qmake on the applications .pro file (<qt-4.8.0-sources>/examples/opengl/hello_gles2&#41;
<br />$ qmake <application&gt;.pro<br />
# Build the application sources as,
<br />$ make<br />
h1. Running Qt apps on target
# 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"
- Copy the application binary and other required resource files on target file-system, say "/root"
- Locate a shell script named "start" in "/bin" folder on target.
- Copy it in your app folder and edit the paths inside it.
- Launch application using same "start" script as,
# ./start /root/app1/app1 -platform eglfs<br />
- NOTE: Before executing any Qt applications on target copy "qt-installs/qt480ga-nxs-qpa-rel" on target at usr/local on target file system
