**********************************
* Compiling linphone on macos X  *
**********************************

You need:
 - Xcode (download from apple or using appstore application)
 - Java SE
 - Macports: http://www.macports.org/
   Download and install macports using its user friendly installer.

- In order to enable generation of bundle for multiple macos version and 32 bit processors, it is recommended to:
	1) edit /opt/local/etc/macports/macports.conf to add the following line:
		macosx_deployment_target 10.6
	2) edit /opt/local/etc/macports/variants.conf to add the following line:
		+universal

- Install build time dependencies
 $ sudo port install automake autoconf libtool intltool wget cunit

- Install some linphone dependencies with macports
 $ sudo port install antlr3 speex libvpx readline sqlite3 libsoup openldap libupnp
 $ sudo port install ffmpeg-devel -gpl2

- Install gtk. It is recommended to use the quartz backend for better integration.
 $ sudo port install gtk2 +quartz +no_x11
 $ sudo port install gtk-osx-application -python27
 $ sudo port install hicolor-icon-theme

The next pieces need to be compiled manually. To ensure compatibility with multiple mac os version it is recommended to do:
 $ export MACOSX_DEPLOYMENT_TARGET=10.6
 $ export CFLAGS="-arch i386 -arch x86_64 -mmacosx-version-min=10.5"
 $ export OBJCFLAGS="-arch i386 -arch x86_64 -mmacosx-version-min=10.5"
 $ export CXXFLAGS="-arch i386 -arch x86_64 -mmacosx-version-min=10.5"
 $ export LDFLAGS="-arch i386 -arch x86_64 -mmacosx-version-min=10.5 -Wl,-headerpad_max_install_names -Wl,-read_only_relocs -Wl,suppress"

- (Optional) libvpx-1.2 has a bug on macos resulting in ugly video. It is recommended to upgrade it manually to 1.3 from source.
  The libvpx build isn't able to produce dual architecture files. To workaround this, configure libvpx twice and use lipo to create a dual architecture
  libvpx.a .

- Install libantlr3c (library used by belle-sip for parsing)
 $ git clone -b linphone git://git.linphone.org/antlr3.git
 $ cd antlr3/runtime/C
 $ ./autogen.sh
 $ ./configure --disable-static --prefix=/opt/local && make
 $ sudo make install

- Install polarssl (encryption library used by belle-sip)
 $ git clone git://git.linphone.org/polarssl.git -b linphone
 $ cd polarssl
 $ ./autogen.sh && ./configure --prefix=/opt/local && make
 $ sudo make install

- Install belle-sip (sip stack)
 $ git clone git://git.linphone.org/belle-sip.git
 $ cd belle-sip
 $ ./autogen.sh && ./configure --prefix=/opt/local && make
 $ sudo make install

- Install srtp (optional) for call encryption
 $ git clone git://git.linphone.org/srtp.git
 $ cd srtp && autoconf && ./configure --prefix=/opt/local && make libsrtp.a
 $ sudo make install

- Install zrtpcpp (optional), for unbreakable call encryption
 $ sudo port install cmake
 $ git clone https://github.com/wernerd/ZRTPCPP.git
 $ cd ZRTPCPP
 $ cmake -DCORE_LIB=true -DSDES=false CMAKE_INSTALL_NAME_DIR=/usr/local/lib/ -DCMAKE_C_FLAGS="-arch i386 -arch x86_64 -mmacosx-version-min=10.5" -DCMAKE_CXX_FLAGS="-arch i386 -arch x86_64 --stdlib=libstdc++ -std=c++11 -lstdc++ -mmacosx-version-min=10.5"  -DCMAKE_C_COMPILER=`xcrun --find clang` -DCMAKE_CXX_COMPILER=`xcrun --find clang` .
$ sudo make install


- Install gsm codec (optional)
 $ git clone git://git.linphone.org/gsm.git
 $ cd gsm
 $ make CCFLAGS="$CFLAGS -c -O2 -DNeedFunctionPrototypes=1"
 $ sudo make install INSTALL_ROOT=/opt/local GSM_INSTALL_INC=/opt/local/include

- Compile and install the tunnel library (optional, proprietary extension only)

 If you got the source code from git, run ./autogen.sh first.
 Then or otherwise, do:

 $ ./configure --prefix=/opt/local && make && sudo make install

- Compile linphone

 If you got the source code from git, run ./autogen.sh first.

 Then or otherwise, do:

 $ PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure --prefix=/opt/local --with-readline=/opt/local --disable-x11 --with-srtp=/opt/local --with-gsm=/opt/local --enable-zrtp --disable-strict && make

 Install to /opt/local

 $ sudo make install

 Done.

If you want to generate a portable bundle, then install gtk-mac-bundler.
Use git:
 $ git clone https://github.com/jralls/gtk-mac-bundler.git
 $ cd gtk-mac-bundler && make install
 $ export PATH=$PATH:~/.local/bin
 #make this dummy charset.alias file for the bundler to be happy:
 $ sudo touch /opt/local/lib/charset.alias

The bundler file in build/macos/linphone.bundle expects some plugins to be installed in /opt/local/lib/mediastreamer/plugins .
If you don't need plugins, remove or comment out this line from the bundler file:
  <binary >
    ${prefix:ms2plugins}/lib/mediastreamer/plugins/*.*.so
  </binary>

Then run, inside linphone source tree:
 Run configure as told before but with "--enable-relativeprefix" appended.
 $ make
 $ make bundle

The resulting bundle is located in linphone build directory, together with a zipped version.

For a better appearance, you can install the gtk-quartz-engine (a gtk theme) that make gtk application more similar to other mac applications (but not perfect).

 $ git clone https://github.com/jralls/gtk-quartz-engine.git
 $ cd gtk-quartz-engine
 $ autoreconf -i
 $ ./configure --prefix=/opt/local CFLAGS="$CFLAGS -Wno-error" && make
 $ sudo make install

Generate a new bundle to have it included.

libiconv hack
*************

The Makefile.am rules used to generate the bundle fetch a libiconv.2.dylib from a linphone download page.
This library adds some additional symbols so that dependencies requiring the iconv from /usr/lib and the ones requiring from the bundle are both satisfied.
In case this library needs to generated, here are the commands:
 $ wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
 $ cd libiconv-1.14
 $ patch -p1 < ../linphone/build/macos/libiconv-macos.patch
 $ ./configure --prefix=/opt/local --disable-static 'CFLAGS=-arch i386 -arch x86_64 -mmacosx-version-min=10.5' 'LDFLAGS=-arch i386 -arch x86_64 -mmacosx-version-min=10.5'  CXXFLAGS="-arch i386 -arch x86_64 -mmacosx-version-min=10.5" && make
 $ make install DESTDIR=/tmp

The resulted library can be found in /tmp/opt/local/lib
