Building Mumble on Windows

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.

The paths used here equal the defaults assumed in the Mumble build files. You are free to change them, but you'll then need to change the file as well. 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 selfbuilt 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".


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

@echo off
SET QTDIR=C:\dev\Qt4.4.1
SET DBUSDIR=C:\dev\dbus
SET MYSQL=c:\dev\mysql
CALL "C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86
SET PATH=%QTDIR%\bin;%DBUSDIR%\bin;c:\dev\OpenSSL\bin;c:\dev\cmake\bin;%MYSQL%\lib\opt;%PATH%;c:\program files\1gnuwin32\bin

Start a new command shell (run cmd.exe) and: (Note: make sure you have Visual C++ Express edition or Visual Studio 2008 and GnuWin32 installed before you run prep.bat or you will get errors).

CD \dev

Whenever something appears

like this

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


Download the most recent version of TortoiseSVN at and install it. The defaults are fine.

Download Mumble SVN

Open c:\dev, rightclick and SVN Checkout...

Repository is

checkout to C:\dev\mumble\

Visual Studio and GnuWin32

You'll need Visual Studio 2008 (or Visual C++ Express Edition) with SP1 and GnuWin32.

Visual Studio 2008 Professional 90 day trial:

Visual C++ Express Edition: (Look at the bottom right corner for "Visual C++ 2008".)

GnuWin32: (First link under the "Download" category.)

When you have installed GnuWin32 go to your "Program Files" directory and rename GnuWin32 to 1GnuWin32 . For some reason when cmake sees this as something it can use if it is not renamed.


Download and and unzip both to C:\dev\

cd \dev\boost_1_3_0
copy ..\boost-jam-3.1.16-1-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_36_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: . At the time of this writing, the latest version is the "Windows SDK for Windows Server 2008 and .NET Framework 3.5". 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 and download the latest SDK. Install it to c:\dev\DXSDK\


From download the lib and bin files for iconv, libxml and zlib. Unpack 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 and unpack it to c:\dev. Rename the top directory to just 'cmake'.

Checkout the SVN of WinDBus from to c:\dev\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 latest OpenSSL source (you can find the latest source at: , get the one that has, in red, [LATEST] next to it. Unpack it to c:\dev\ (it will create a directory called openssl-x.y.z)

Download and install ActivePerl. You can find it here:

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

cd \dev
cd openssl<Press tab and it will autocomplete to, as of this writing, openssl-0.9.8h>
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: . Use a custom install and install only the headers and libraries. Use c:\dev\MySQL as the base directory. To do this go through the installer until you come to a window that says "Custom Setup" at the top. You will see five parent selections: MYSQL Server, Client Programs, etc. On all of the first four click on the little hard drive icon and select "This feature will not be available." On the last one--the fifth--click the red X and select "This feature, and all subfeatures, will be installed on local hard drive." Proceed through the installer.


Download and unzip to C:\dev. Rename the directory from qt-win-opensource-src-4.4.1 to Qt4.4.1


cd \dev
cd Qt4.4.1
patch -p0 < path/to/qt441msvc.patch
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.

Building Mumble and Murmur

Once all of the above is done... Open C:\dev\mumble\src\mumble\ and remove the line which says CONFIG += asio. That is only needed for ASIO support, which requires downloads of proprietary ASIO SDK to compile.

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

cd \dev\mumble
nmake clean
