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

Qt5 eglfs/QPA

Building Qt 5

  1. Obtain qt-5.0.0 from git [qt-project.org] (follow instructions in “Getting the source code”)
  2. Obtain 7425 specific files from qt-platform-mkspecs git [gitorious.org] (look for folder “5.0”)
  3. Copy folder named “linux-nxs-mipsel-uclibc-g++” from 7425 specific repo to <qt-5.0.0-git>/qtbase/mkspecs
  4. 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
  5. Apply patch “7425-eglfs.patch” from 7425 specific repo to <qt-5.0.0-git>/src
    • $$ cd <qt-5.0.0-git>/src
    • $$ patch -p1 < 7425nxs-eglfs.patch
  6. Configure Qt in qtbase folder as,
    • $$ configure -prefix /usr/local/qt-installs/qt5 -arch mips -qpa -xplatform linux-nxs-mipsel-uclibc-g++ \
    • -depths 16,24,32 -no-largefile -opensource -verbose -system-zlib -system-libpng -system-libjpeg \
    • -system-freetype -fast -opengl -confirm-license -release -make libs -no-wayland -no-xcb
  7. After the build succeeds set following environment variables before building any opengl Qt Apps,
    • - set QTDIR=/usr/local/qt-installs/qt5
    • - set PATH=/usr/local/qt-installs/qt5/bin:$PATH

NOTE: Before executing any Qt applications on target copy “qt-installs/qt5” on target at usr/local on target file system
