Building
********

WARNING: During the build, windows might slow down suddenly. Using ctl+alt+del to start the windows system monitor,
 you might see a process 'LVpSRV.exe' or something like this that eats 90% of cpu.
Kill it. Don't know what it is, but once killed, windows runs normally.

#use ActiveState perl instead of mingw perl

******************************************************
*      Notes about linphone-deps generation          *
******************************************************

Linphone-deps is a collection of linphone dependencies, that are for some of them difficult
to find as windows binaries.
These notes are useful if you want to upgrade part of the software that is included in the
linphone-deps packages.

List of software included in linphone-deps:
libosip2  (compiled)
libeXosip2 (compiled)
libavcodec, libavutil, libavformat, libavdevice, libswscale (compiled, all these from ffmpeg)
libtheora (from the web)
libx264 (compiled from the version distributed from linphone's web site)
libogg (from the web)
libspeex, libspeexdsp (compiled, statically to workaround a dll-related crash)
libgnutls (from the web)
libgsm (from the web)
libxml2 (compiled)
libsoup (compiled)


- building ffmpeg 
  ./configure --enable-shared --disable-static --enable-memalign-hack --extra-cflags="-fno-common" --enable-gpl && make
  make install DESTDIR=~/ffmpeg-install
  Copy to ~/ffmpeg-install/usr/local/* to linphone-deps/.
  Copy also all *.dll.a files from the build tree to lib/ directort of linphone-deps. These are the implibs necessary to link a program against the dlls.

- building libxml2: the binaries found on the internet are generated with MSVC++, and for obscure reason they are not suitable for building libsoup 
  (that requires libxml2).
  ./configure --enable-shared --disable-static && make && make install DESTDIR=~/libxml2-install
  copy ~/libxml2-install/usr/local/* into linphone-deps/.

- building x264:
  
  * Download lastest snapshot the linphone fork of x264 from
  http://download.savannah.gnu.org/releases/linphone/plugins/sources/
  This fork just brings the H264 Nalu size control feature, necessary to make video packet that fits into the network mtu.
  It will be no longer necessary as soon as x264 official project will accept this patch or a similar one.

  * download yasm normal version windows executable from yasm project page:
  http://www.tortall.net/projects/yasm/wiki/Download
  copy it as /usr/local/bin/yasm.exe

  uncompress the x264 tarball
  cd into x264/ dir then run:
  ./configure --enable-pic
  make
  make install DESTDIR=~/x264-install
  then copy the content of ~/x264-install/usr/local/ into linphone-deps/.
