Mumble has quite a few dependencies for building on Windows, and as the feature set grows, so does the list of dependencies. This page will try to detail the steps required to set up a Win32 build environment suitable for compiling the current code found in our repository. Be aware that this steps might not work for older revisions of Mumble as dependencies might have been removed or updated to an incompatible version in the meantime.

The paths used here equal the defaults assumed in the Mumble build files. You are free to change them, but you might need to adjust the build files themselves. If you find any problems or incorrect steps in this article please either correct them or contact us and we will try our best to resolve the issue.

Also note, that if you are submitting a bug report for a self-built executable, we expect you to either

  • Follow these instructions to the letter


  • Report any deviations from these instructions

Deviations means anything, from "I installed to the D: drive" to "I changed the gcc build options for Qt" or "I used another version of Speex".


Visual Studio

You'll need Visual Studio 2008 (or Visual C++ Express Edition) with SP1.

Visual Studio 2008 Professional 90 day trial: http://msdn2.microsoft.com/en-us/vs2008/products/cc268305.aspx

Visual C++ Express Edition: http://www.microsoft.com/express/vc/ (Look at the bottom right corner for "Visual C++ 2008.")

Intel C++ Compiler

You can also use the Intel C++ Compiler in conjuction with VS2008. You can find it here: http://www.intel.com/cd/software/products/asmo-na/eng/368972.htm

This is strictly optional and you can compile a perfectly working version of Mumble without this compiler following this guide. This guide does not give information on how to use the Intel compiler with VS2008 to compile Mumble, so you will need to either have the programming experience necessary to know how to do this or find the procedures to do so elsewhere.


Download the most recent Git from http://code.google.com/p/msysgit/downloads/list and install it. Make sure you select "Run Git from the Windows Command Prompt."


Download the most recent version of TortoiseSVN at http://tortoisesvn.net/downloads and install it. The defaults are fine.

Note: TortoiseSVN is only need to checkout the SVN of WinDBus. You can skip this step.

Create the bat file

Create C:\dev, and inside that directory create a file prep.bat containing:

@echo off
SET QTDIR=C:\dev\Qt4.5.2
SET DBUSDIR=C:\dev\dbus
SET VLD_DIR=C:\dev\vld
SET MYSQL=c:\dev\mysql
SET ICE=c:\dev\Ice
CALL "%DXSDK_DIR%\Utilities\bin\dx_setenv.cmd"
CALL "%PROGRAMFILES(X86)%\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86
) ELSE (
CALL "%PROGRAMFILES%\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86
SET PATH=%QTDIR%\bin;%DBUSDIR%\bin;c:\dev\OpenSSL\bin;c:\dev\libsndfile;c:\dev\cmake\bin;%MYSQL%\lib\opt;%ICE%\bin;c:\dev\protobuf-2.2.0\vsprojects\Release;%PATH%

change the last line to

SET PATH=%QTDIR%\bin;%DBUSDIR%\bin;c:\dev\OpenSSL\bin;c:\dev\libsndfile;c:\dev\cmake\bin;%MYSQL%\lib\opt;%ICE%\bin;c:\dev\protobuf-2.2.0\vsprojects\Release;C:\dev\libogg\win32\VS2008\Win32\Release;%PATH%

if you're compiling Mumble 1.1.x.

Start a new command shell (run cmd.exe) (Make sure you have Microsoft Visual C++ and Git installed before you run prep!)

cd \dev

After you run prep make sure a message similar to "Setting environment for using Microsoft Visual Studio 2008 x86 tools" appears.

Whenever something appears

like this

you're supposed to enter it in that command shell (or copy it from this webpage and right click in the command window and select Paste). When you later want to compile things, remember to call prep.bat first to set paths correctly.

Note to those following this guide: When you extract compressed files, sometimes they will have container folders and sometimes they will not. Please ensure (for example) that when you extract a compressed file like QT4.5.1, that you see "bin" "include" and such folders as that directly inside of the folder named "Qt4.5.1". If you just see one folder and no other files, you have done it wrong.


Download http://prdownloads.sf.net/boost/boost_1_40_0.7z?download and http://prdownloads.sf.net/boost/boost-jam-3.1.17-1-ntx86.zip?download and unzip both to c:\dev

cd \dev 
cd boost_1_40_0
copy ..\boost-jam-3.1.17-1-ntx86\bjam.exe
bjam --toolset=msvc --prefix=C:\dev\Boost install

This might take a while, but when done you'll have Boost installed. Note that none of the other build dependencies do themselves depend on boost, so if you want you can just continue in a new command shell (but remember to call prep.bat). Once all is done, you can safely delete the boost_1_40_0 and boost-jam directories. If you get the warning, that some targets were skipped or failed, it can be ignored for our purposes.

Microsoft Windows SDK

Go here to download: http://www.microsoft.com/downloads/details.aspx?FamilyID=c17ba869-9671-4330-a63e-1fd44e0e2505&displaylang=en . At the time of this writing, the latest version is the "Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 SP1". Install it to C:\dev\WinSDK

As you are going through the installer you will come to a window where you will see two main categories and then subcategories below them. Uncheck the green check boxes next to “Documentation” and “Samples”. Continue with the installation. These take a long time to download and are not really needed for Mumble.

Microsoft DirectX SDK

Go to http://msdn.microsoft.com/directx/sdk/ and download the latest SDK. Install it to c:\dev\DXSDK

Visual Leak Detector

Download VLD and install it to C:\dev\vld\.

If you're using Visual C++ Express Edition, you will need to manually extract the files using a tool like 7-zip . Extract it to C:\dev\ and rename it to vld.

Note: VLD is only enabled for debug builds.


From http://www.winkde.org/pub/kde/ports/win32/repository/win32libs/ download the following archives:

  • zlib*lib.zip
  • zlib*bin.zip
  • iconv*lib.zip
  • iconv*bin.zip
  • libxml2*bin.tar.bz2
  • libxml2*lib.tar.bz2

Whereas * represents the newest version on the server. Unpack all of them to 'c:\Program Files\win32libs'. If you have extracted them all correctly you should see inside of 'c:\Program Files\win32libs' "include," bin," lib," and "manifest" folders. Note that you may also download the dbus library from there, but if you do it will not automatically spawn dbus-daemon as that needs patching.

Download CMake and unpack it to c:\dev. Rename the top directory to just 'cmake'.

Checkout the SVN of WinDBus from https://windbus.svn.sourceforge.net/svnroot/windbus/trunk to c:\dev\windbus

If you skipped installing TortoiseSVN, download http://windbus.svn.sourceforge.net/viewvc/windbus/trunk.tar.gz?view=tar and extract the archive to c:\dev\. Rename the extracted trunk folder to windbus.

cd \dev 
mkdir windbus-build
cd windbus-build
cmake -DCMAKE_BUILD_TYPE=Release -DDBUS_INSTALL_SYSTEM_LIBS=ON -G "NMake Makefiles" c:\dev\windbus\cmake
nmake install

Regardless of what you say, Windbus is installed to c:\<Program Files>\dbus. Move that entire directory into c:\dev (so it ends up as c:\dev\dbus)

Copy all .dll files from c:\Program Files\win32libs\bin to c:\dev\dbus\bin

You can remove the c:\dev\windbus and c:\dev\windbus-build directories at this point.


Download the OpenSSL source named "openssl-0.9.8g.tar.gz" from here http://www.openssl.org/source/. Unpack it to c:\dev (it will create a directory called openssl-x.y.z)

Download and install ActivePerl from here: http://www.activestate.com/activeperl/

Open a new shell (so that %PATH% includes ActivePerl).

cd \dev
cd openssl<press tab>
perl Configure VC-WIN32 --prefix=c:\\dev\\OpenSSL
nmake -f ms\ntdll.mak
nmake -f ms\ntdll.mak install

You can remove c:\dev\openssl-x.y.z after this.


Download the latest release of MySQL Server. It can be found here: http://dev.mysql.com/downloads/mysql/5.1.html#win32 (select "Without installer (unzip in C:\)"). Unzip it to c:\dev\MySQL.


Download ftp://ftp.trolltech.com/qt/source/qt-win-opensource-src-4.5.2.zip and unzip to c:\dev. Rename the directory from qt-win-opensource-src-4.5.2 to Qt4.5.2

Download http://mumble.sourceforge.net/qt450msvc.patch and put it in c:\dev\Qt4.5.2. Then, start Git Bash, which came with git.

cd /c/dev/Qt4.5.2
patch -lp0 < qt450msvc.patch

Start a regular command shell:

cd \dev
cd Qt4.5.2
configure -debug-and-release -qt-sql-sqlite -qt-sql-mysql -no-qt3support -no-exceptions -qt-zlib -qt-libpng  -qt-libjpeg  -openssl-linked -dbus-linked -I c:\dev\OpenSSL\include -L c:\dev\OpenSSL\lib -I c:\dev\dbus\include -L c:\dev\dbus\lib -I c:\dev\mysql\include -L c:\dev\mysql\lib\opt -platform win32-msvc2008

This will also take quite a while.

The demos and examples need a lot of time and disk space. You can skip them. Add the following parameter to the configure line:

-nomake demos -nomake examples

This saves time, disk space, and nerves.

Protocol Buffers

Download Protocol Buffers from Google (protobuf-x.y.z.zip) and unpack it to c:\dev\protobuf-z.y.z. Follow the documentation in c:\dev\protobuf-x.y.z\vsprojects\readme.txt. Note that if the release number changes you will need to change prep.bat to whatever z.y.z changed to or you won't be able to call protoc.exe.


Download the binary release from http://www.mega-nerd.com/libsndfile/#Download and install it to c:\dev\libsndfile\ . Make sure the libsndfile-1.dll is visible to the executables.

Note: This dependency is not needed for the server.


Download the latest libogg-1.x.x.zip from http://downloads.xiph.org/releases/ogg/ and unpack it to c:\dev\libogg.

If you want to compile Mumble 1.1.x, you need to go to C:\dev\libogg\win32\VS2008, build the release builds of libogg, and copy C:\dev\libogg\win32\VS2008\Win32\Release_SSE2\libogg.lib to the new Folder C:\dev\libogg\lib\.

Note: This dependency is not needed if you do not want to compile the Mumble compatibility client (Mumble 1.1.x). The Mumble compatibility client can be disabled by passing CONFIG+=no-11x to qmake. This dependency is not needed for building the server.

ZeroC Ice

Download the latest version of ZeroC Ice from http://www.zeroc.com/download.html and make sure you select the VS2008 version. Install to c:\dev\Ice

Note: Ice can be disabled by passing CONFIG+=no-ice to qmake. Bear in mind that the Ice RPC Interface is the recommended way to control the server. This dependency is not needed for building the client.


Download the bonjour sdk from http://developer.apple.com/networking/bonjour/download/ and install it to c:\dev\Bonjour\ .

Note: Bonjour can be disabled by passing CONFIG+=no-bonjour to qmake.


Download the G15 software from here: http://www.logitech.com/index.cfm/434/180&cl=us,en?WT.ac=sc%7Cdownloads%7C%7Cdd and install it.

Now go to C:\Program Files\Logitech\GamePanel Software\LCD Manager\SDK and extract "LCDSDK_3.02.173.zip". Take the folder that has been extracted and rename it to G15SDK. Put this folder into c:\dev.

Note: Support for G15 Displays can be disabled by passing CONFIG+=no-g15 to qmake.

Download Mumble and Submodules

To clone the repositories :

cd \dev
git clone git://mumble.git.sourceforge.net/gitroot/mumble/mumble mumble
cd mumble
git submodule init
git submodule update

To use the v1.1.x branch (which you most likely do) run this command after running the commands above:

git checkout --track -b v1.1.x origin/v1.1.x

If you are using the current branch, you will need to open git bash and cd to the mumble folder that was created. Now cd to


and then do

sh mklinks.sh

Building Mumble and Murmur

Once all of the above is done we can get to compiling Mumble itself.

If you want to have ASIO support you have to install an additional, proprietary, ASIO SDK.

There are four dependencies that most people who make their own compiles will not need: g15, asio, bonjour, and 11x. The bonjour dependency is useful if you want to browse servers across a local network, but you can disable it if this feature is not needed.

To compile Mumble without Mumble 1.1.x, replace the qmake command below with this one:

qmake CONFIG+=no-11x CONFIG+=no-asio CONFIG+=no-g15 CONFIG+=no-bonjour -recursive

To compile Mumble with Mumble 1.1.x, replace the qmake command below with this one:

qmake CONFIG+=no-asio CONFIG+=no-bonjour CONFIG+=no-g15 -recursive

Note that the compile will fail if you leave out these build flags and do not have the SDK required.

To compile Mumble:

cd \dev
cd mumble
nmake clean

Note that this builds the debug versions, which is what we strongly recommend to use while developing. If you want to send the binary to someone else, use

nmake release

instead of the last


command listed above. This will result in a much smaller binary with fewer dependencies.

Running Mumble and Murmur

Once compiled, you can go into c:\dev\mumble\release or (\debug if you compiled the debug version) and can execute mumble.exe or murmur.exe. Before executing Mumble or Murmur you need to open a command prompt and do

cd \dev
cd mumble\debug (or release)

Then execute either Mumble or Murmur from the command prompt with




If you want to run the release build directly from Windows Explorer, you will need to collect all the library files into one folder, along with the executables you built when you compiled Mumble. Have a look at the files the official Mumble installer creates in Program Files\Mumble to find out which files you will need.
