Linphone is an open source softphone for voice and video over IP calling and instant messaging.

It is fully SIP-based, for all calling, presence and IM features.

General description is available from linphone web site

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
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 the PATH to the Qt5 bin. 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 in 3 steps. First, you need to build the SDK, then the submodule Minizip and finally, the application.

Create your build folder at the root of the project : mkdir build-desktop Go to this new folder and begin the build process : cd build-desktop
Prepare your options : cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo By default, it will try compile all dependencies. You can remove some by adding -ENABLE_<COMPONENT>=NO to the command. You can use cmake-gui .. if you want to have a better access to them.
Build the SDK : cmake --build . --target sdk --config RelWithDebInfo. You can add --parallel 10 if you have CMake>3.12 to speedup the process.
Build The submodule. cmake .. and cmake --build . --target install --config RelWithDebInfo
Finish the process with a new cmake .. and cmake --build . --target install --config RelWithDebInfo.

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, 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.

You can find a script file for each supported platform to achieve the first building. They only exist for convenience. There are called build_all_linux.sh, build_all_macos.sh and build_all_win.bat.

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 or Qt 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 and PATH 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.

Languages

Linphone is getting a full internationalization support, using Transifex platform. If you want you can contribute at: https://www.transifex.com/belledonne-communications/linphone-desktop/languages/

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
