Building on Linux

These are instructions for performing a regular build using the libraries that are shipped with your distribution. For instructions to build a static version of Mumble, checkout this file.

Dependencies

In order to install the needed dependencies on Ubuntu, you have to run the following command:

sudo apt install \
  build-essential \
  cmake \
  pkg-config \
  qt5-default \
  qttools5-dev \
  qttools5-dev-tools \
  libqt5svg5-dev \
  libboost-dev \
  libssl-dev \
  libprotobuf-dev \
  protobuf-compiler \
  libprotoc-dev \
  libcap-dev \
  libxi-dev \
  libasound2-dev \
  libogg-dev \
  libsndfile1-dev \
  libspeechd-dev \
  libavahi-compat-libdnssd-dev \
  libzeroc-ice-dev

If you intend to include grpc-support for the Mumbe server (murmur), you also have to install the following packages: libgrpc++-dev and protobuf-compiler-grpc

If you are using a distribution that is not based on Ubuntu, you probably have to change the command accordingly.

You will need cmake v3.15 or later. If the version shipped by your distribution is not recent enough, you can install a recent one via the official PPA by following the instructions on the linked page.

Running cmake

It is recommended to perform a so-called "out-of-source-build". In order to do so, navigate to the root of the Mumble directory and then issue the following commands:

1. mkdir build (Creates a build directory)
2. cd build (Switches into the build directory)
3. cmake .. (Actually runs cmake)

This will cause cmake to create the necessary build files for you. If you want to customize your build, you can pass special flags to cmake in step 3. For all available build options, have a look here.

E.g. if you only want to build the server, use cmake -Dclient=OFF ...

Building

By default cmake will create Makefiles if run on Linux, so in order to build, you can simply run make in the build directory. If you want to parallelize the build (to speed things up), you can use make -j $(nproc).

If you want to stay independent of the type of the generated build files, you should issue cmake --build . (from the build directory) in order to start the compilation. If you want to parallelize the build, use cmake --build . -j <jobs> where <jobs> is the amount of parallel jobs to be run concurrently. A good choice usually is <jobs> = $(nproc).
