h1. 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)
    # 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)
  2. Follow the instructions in "AppLibsInstallationBuildGuide.pdf" to build Applibs

Qt 4.8 eglnullws / QWS

This details steps to build Qt with Qt's OpenGL graphics driver.

This OpenGL graphics driver supports execution of Single Qt app that uses QGLWidget as full-screen (examples/opengl/hello_gles2)
# 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/qws
# 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
'

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-qws-rel
'
PATH=/usr/local/qt-installs/qt480ga-nxs-qws-rel/bin:$PATH
# Ensure that following environment variables in the shell are set,

'
BCM_NEXUS_PATH=<path-till-Applibs-folder>/nexus
' BCM_TARGET_LIBDIR=<path-till-nfsrootfs-base-folder>/romfs/lib
'

# Invoke qmake on the applications .pro file (<qt-4.8.0-sources>/examples/opengl/hello_gles2)

<br />$ qmake <application>.pro<br />


# Build the application sources as,

<br />$ make<br />


h1. Running Qt apps on target


# Ensure that folder "qt-installs/qt480ga-nxs-qws-rel" is copied on target file system at "/usr/local"
' Note- after copying, the path should appear as "/usr/local/qt-installs/qt480ga-nxs-qws-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,

<br /># ./start /root/app1/app1 -qws -display eglnullws<br />
