Linphone for iPhone depends on liblinphone SDK. This SDK is generated from makefiles and shell scripts.
You must first install both Xcode with iPhone OS SDK and HomeBrew or MacPorts for these scripts to work.
- Using HomeBrew:
brew install automake intltool libtool pkg-config coreutils yasm nasm wget imagemagick
# then you have to install antlr3 from a tap.
wget https://gist.githubusercontent.com/Gui13/f5cf103f50d34c28c7be/raw/f50242f5e0c3a6d25ed7fca1462bce3a7b738971/antlr3.rb
mv antlr3.rb /usr/local/Library/Formula/
brew install antlr3
- Using MacPorts:
sudo port install coreutils automake autoconf libtool intltool wget pkgconfig cmake gmake yasm nasm grep doxygen ImageMagick optipng antlr3
- For this part, we assume that
LOCAL_BIN_DIR
is set as following depending on which tool you use:
For MacPorts: LOCAL_BIN_DIR=/opt/local/bin
For HomeBrew: LOCAL_BIN_DIR=/usr/local/bin
- Modify your
PATH
so that the tools are taken in place of the versions brought by Apple in/usr/bin
. Otherwise the build will fail with obscure errors:
export PATH=$LOCAL_BIN_DIR:$PATH
- Install gas-preprosessor.pl (version above July 2013) into your
LOCAL_BIN_DIR
directory
wget --no-check-certificate https://raw.github.com/yuvi/gas-preprocessor/master/gas-preprocessor.pl
chmod +x gas-preprocessor.pl
sudo mv gas-preprocessor.pl $LOCAL_BIN_DIR
- Link
libtoolize
toglibtoolize
sudo ln -s $LOCAL_BIN_DIR/glibtoolize $LOCAL_BIN_DIR/libtoolize
- Link host's
strings
to simulator SDK
sudo ln -s /usr/bin/strings /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/strings
- GPL third parties versus non GPL third parties
This SDK can be generated in 2 flavors. First is with GPL third parties, it means liblinphone includes GPL third parties like FFMPEG or X264. If you choose this flavor, your final application must comply with GPL in any case. This is the default mode.
To generate the liblinphone multi arch sdk in GPL mode, do:
cd submodules/build && make all
ALTERNATIVELY, you can force liblinphone to use only non GPL code except for liblinphone, mediastreamer2, oRTP, belle-sip. If you choose this flavor, your final application is still subject to GPL except if you have a commercial license for liblinphone, mediastreamer2, oRTP, belle-sip.
To generate the liblinphone multi arch sdk in non GPL mode, do:
cd submodules/build && make all enable_gpl_third_parties=no
- For Xcode prior to 4.5, use:
make -f Makefile.xcode4.4
- ZRTP support
You can disable ZRTP support with:
make all enable_zrtp=no
- In case you upgrade your IOS SDK, you may force rebuilding everything, by doing
make veryclean && make all
The resulting sdk is in liblinphone-sdk/
root directory.
After the SDK is built, just open the Linphone Xcode project with Xcode, and press Run
.
- Note regarding third party components subject to license:
The liblinphone-sdk is compiled with third parties code that are subject to patent license, specially: AMR, SILK G729 and H264 codecs. Linphone controls the embedding of these codecs thanks to the preprocessor macros HAVE_SILK, HAVE_AMR, HAVE_G729 HAVE_OPENH264 positioned in Xcode project. Before embedding these 4 codecs in the final application, make sure to have the right to do so.
