Linphone is a free VoIP and video softphone based on the SIP protocol.
Here are the general instructions to build linphone for desktop. The specific instructions for each build platform is described just below.
Install some build tools:
Java(build dependency for
Qt5(5.9 or newer).
C++11support is required!
It's necessary to set the environment variable
Qt5_DIRto point to the path containing the cmake folders of Qt5. Example:
PATHenvironment variable must point to the Qt5 directory
Prepare the build by running the
Build the project using the appropriate build tool (
Visual Studio (2013 or 2015 version)).
Specific instructions for the GNU/Linux and Mac OS X platforms
Prepare the build in a terminal by running the following command in the current directory:
Build the project in a terminal with:
Specific instructions for the Windows platform
Ensure that you have downloaded the
Qt msvc2015 version(32-bit). (64-bit version is not supported at this moment by Linphone Desktop.)
MinGWmust be installed too.
PATHenvironment variable to the Qt5 installation path:
Open a Windows command line (cmd.exe) in the current directory and run:
python prepare.py -G "Visual Studio 14 2015"
Open the generated Visual Studio solution
Project.sln.lnkand build it. Check if the
Releaseoption is selected in Visual Studio. (With
Known bugs and issues

Customizing your build
Some options can be given during the
prepare.py step to customize the build. The basic usage of the
prepare.py script is:
Here are the main options you can use.
Building with debug symbols
Building with debug symbols is necessary if you want to be able to debug the application using some tools like GDB or the Visual Studio debugger. To do so, pass the
--debug option to
./prepare.py --debug [other options]
Generating an installation package (on Windows and Mac OS X platforms)
You might want to generate an installation package to ease the distribution of the application. To add the package generation step to the build just run:
./prepare.py --package [other options]
Activate the build of all codecs
Using more advanced options
prepare.py script is wrapper around CMake. Therefore you can give any CMake option to the
To get a list of the options you can pass, you can run:
The options that enable you to configure what will be built are the ones beginning with
ENABLE_. So for example, you might want to build linphone without the opus codec support. To do so use:
Updating your build
Simply re-building using the appropriate tool corresponding to your platform (make, Visual Studio...) should be sufficient to update the build (after having updated the source code via git). However if the compilation fails, you may need to rebuild everything from scratch using:
./prepare.py -c && ./prepare.py [options]
Then you re-build as usual.
