Libbrowsernode Build Instructions

Build instructions on Ubuntu 12.04.4:

• Install the following packages: git-core gyp cmake libvdpau-dev

• Download Berkelium Sources:

  git clone git://github.com/sirikata/berkelium
  cd berkelium
  git submodule update --init --recursive
  ./util/build-chromium.sh --deps --force
  

• The Chromium sources will download. Once the download completes, and the building begins, manually patch build/chromium/src/net/base/x509_certificate_nss.c as follows:

  --- x509_certificate_nss.cc 2014-02-08 22:57:17.379760998 +0000
  +++ x509_certificate_nss.cc 2014-02-09 09:21:17.633417195 +0000

  +#if NSS_VMINOR >= 15
  +  typedef char* (*CERTGetNameFunc)(CERTName const* name);
  +#else
  +  typedef char* (*CERTGetNameFunc)(CERTName* name);
  +#endif
  

• Allow the build to complete normally. This will take several hours, and requires around 4GB of RAM at times.

• Once the Chromium build completes, build Berkelium as follows:

  cmake . -DCMAKE_BUILD_TYPE=Release
  make
  sudo make install
  

• It may well be that Berkelium fails to build at the linking stage. If so, edit the file CMakeFiles/libberkelium.dir/link.txt and remove all instances of the string -ljpeg. Be sure to only select -ljpeg and nothing else. Save the file and run make again to complete the build.

• Run the following to build the libbrowsernode library:

  touch a.cpp
   g++ -c a.cpp -o a.o
   g++ a.o  -shared -llibberkelium -o libberkeliumwrapper.so
  

• Copy the resulting libberkeliumwrapper.so to /usr/lib

  sudo ldconfig
  

• Copy resources.pak, libffmpegsumo.so, chrome.pak and berkelium from /usr/local/bin to /usr/bin

• Download Libavg 1.7.1 Sources:

  sudo apt-get install subversion automake autoconf libtool libxml2-dev \
  libpango1.0-dev librsvg2-dev libgdk-pixbuf2.0-dev libavcodec-dev libavformat-dev \
  libswscale-dev python-dev libboost-python-dev libboost-thread-dev g++ libSDL-dev \
  libxxf86vm-dev libdc1394-22-dev linux-libc-dev libvdpau-dev
  
  svn co -r 9546 https://www.libavg.de/svn/trunk/libavg
  
  cd libavg
  

• Download libbrowsernode patches [3]

• Copy the browsernode release files in to src/test/plugin folder.

• Copy the Berkelium header files in to src/test/plugin (ie src/test/plugin/berkelium)

• Copy /usr/local/lib/liblibberkelium.so in to src/test/plugin

• Build libavg as normal:

  ./bootstrap
  ./configure --enable-dc1394 --enable-v4l2
  make
  sudo make install
