h2. 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":http://get.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.8.0.tar.gz and extract it in a working folder
- Obtain 7425 specific files from "qt-platform-mkspecs git":http://gitorious.org/qt-platform-mkspecs (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
' for example,
' $ export BCM_APPLIBS_PATH=/home/qtnokia/WorkDir/97425-P1/stb-rs_p2-al_p2dot1/AppLibs
' $ export BCM_NEXUS_PATH=/home/qtnokia/WorkDir/97425-P1/stb-rs_p2-al_p2dot1/nexus
# Apply patch "7425nxs-eglfs.patch" to eglfs Qt Lighthouse Driver located at <qt-4.8.0-sources>/src/plugins/platforms/eglfs
' $ cd <qt-4.8.0-sources>/src/plugins/platforms/eglfs
' $ patch -p4 < 7425nxs-eglfs.patch
# Configure Qt as,
' $ 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-qt3supportprefix /usr/local/qt-installs/qt480ga-nxs-qpa-rel
# Build Qt as,
'$ make
# Install Qt on host as,
' $ make install
h2. 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;
' $ qmake <application>.pro
# Build the application sources as,
' $ make
h2. Running Qt apps on target
# Ensure that folder "qt-installs/qt480ga-nxs-qpa-rel" is copied on target file system at "/usr/local"
' Note
- 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
NOTE: Before executing any Qt applications on target copy "qt-installs/qt480ga-nxs-qpa-rel" on target at usr/local on target file system
