Getting started
Here are the general instructions to build linphone for desktop. The specific instructions for each build platform is described just below. You will need the tools defined for Linphone-SDK 4.3 :
- cmake >= 3.6
- python = 2.7 (python 3.7 if C# wrapper generation is disabled)
- pip
- yasm
- nasm
- doxygen (required for the Cxx Wrapper)
- Pystache (use pip install pystache)
- six (use pip install six)
- Perl (can be downloaded at http://strawberryperl.com/ for Windows. Set your Path to perl binaries)
For Desktop : you will need Qt5
(5.9 or newer). C++11
support is required!
Set your environment
-
It's necessary to install the
pip
command and to execute:pip install pystache
-
You have to set the environment variable
Qt5_DIR
to point to the path containing the cmake folders of Qt5, and thePATH
to the Qt5bin
. Example:Qt5_DIR="~/Qt/5.9/gcc_64/lib/cmake" PATH="~/Qt/5.9/gcc_64/bin/:$PATH"
Note: If you have qtchooser
set in your PATH
, the best use is :
eval "$(qtchooser -print-env)"
export Qt5_DIR=${QTLIBDIR}/cmake/Qt5
export PATH=${QTTOOLDIR}:$PATH
Building
The build is done by building the SDK, the submodule Minizip and the application. Their targets are sdk
, miniziplib
and linphone-qt
.
-
Create your build folder at the root of the project :
mkdir build
Go to this new folder and begin the build process :cd build
-
Prepare your options :
cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo
. By default, it will try compile all needed dependencies. You can remove some by adding-DENABLE_<COMPONENT>=NO
to the command. You can usecmake-gui ..
if you want to have a better access to them. You can add-DCMAKE_BUILD_PARALLEL_LEVEL=10
to do 10 parallel builds for speeding up the process. If it doesn't seem to work then it will be better to use CMake >= 3.12 Also, you can add-DENABLE_BUILD_VERBOSE=ON
to get more feedback while generating the project. -
Build and install the whole project :
cmake --build . --target all
orcmake --build . --target ALL_BUILD
on Windows.
It is important to set the config in the process or you can have a bad configuration for your binary that could lead to some corruption : on Windows, this issue is spotted when trying to start the application and an empty file with a random name is created. So, if you are working on an IDE (like Qt Creator), you may override the build command.
When all are over, the files will be in the OUTPUT folder in the build directory. When rebuilding, you have to use cmake --build . --target install
or cmake --install .
(if CMake>=3.15) to put the application in the correct configuration.
-
When doing some modifications in the SDK, you can rebuild only the sdk with the target
sdk
-
In order to get packages, you can use
cmake .. -DENABLE_APP_PACKAGING=YES
. The files will be inOUTPUT/packages
folder.
General Troubleshooting
- The latest version of Doxygen doesn't work with the SDK. If you have a specific version of Doxygen that is not in your PATH, you can use
-DLINPHONESDK_DOXYGEN_PROGRAM
.
Eg on Mac : -DLINPHONESDK_DOXYGEN_PROGRAM=/Applications/Doxygen.app/Contents/Resources/doxygen
- If the build of the SDK crash with something like "cmd.exe failed" and no more info, it can be a dependency that is not available. You have to check if all are in your PATH. Usually, if it is about VPX or Decaf, this could come from your Perl installation.
Mac OS X Troubleshooting
To install the required dependencies on Mac OS X, you can use Homebrew. Before you install packages with Brew, you may have to change directories permissions (if you can't change permissions with sudo on a MacOS >= High Sierra, get a look at this StackOverflow answer).
-
First ensure you have installed pip. You can get it for python 2.7 there.
-
Then, you can install a pip package with the following command:
pip install [package]
For instance, if you don't have pystache and the dot package (contained in graphviz), enter the following commands:
pip install pystache pip install graphviz
Specific instructions for the Windows platform
-
Ensure that you have downloaded the
Qt msvc2015 version
orQt msvc2017 version
(32-bit). (64-bit version is not supported at this moment by Linphone Desktop.)MinGW
must be installed too. -
Define the
Qt5_DIR
andPATH
environment variable to the Qt5 installation path:Qt5_DIR="C:\Qt\<version>\msvc2017\lib\cmake" PATH="C:\Qt\<version>\msvc2017\bin;%PATH%"
-
Or open a Command line with Visual Studio
Developer Comand Prompt for VS 2017
and call qtenv2.bat that is in your qt binaries eg: C:\Qt\5.12.6\msvc2017\bin\qtenv2.bat -
Install msys-coreutils :
mingw-get install msys-coreutils
-
Build as usual with adding
-A Win32
to each command (General Steps) -
The project folder will be in the build directory.

Known bugs and issues
- 4K (High DPI Displays) If you encounter troubles with high DPI displays on Windows, please to see this link: https://bugreports.qt.io/browse/QTBUG-53022
Updating your build
You need to update the project:
git pull --rebase
git submodule sync && git submodule update --init --recursive
Then 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 (Delete all files in your build-desktop folder).
Then you re-build as usual.

Feedback or bug reporting
Launch the application with --verbose
parameter to get full logs and send it with your request.
On some OS (like Fedora 22 and later), they disable Qt debug output by default. To get full output, you need to create ~/.config/QtProject/qtlogging.ini
and add :
[Rules]
*.debug=true
qt.*.debug=false
