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 (follow instructions in "Getting the source code")
  2. Obtain 7425 specific files from qt-platform-mkspecs git (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

  1. 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

  1. 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

  1. 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
