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 mumble.pro file as well.
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
or
- 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".
Preparations
Create C:\dev, and inside that directory create a file prep.bat containing:
@echo off SET QTDIR=C:\dev\Qt4.3.1 SET DBUSDIR=C:\dev\dbus SET INCLUDE= SET LIB= SET PATH=C:\dev\MinGW\bin;%QTDIR%\bin;%DBUSDIR%\bin;C:\dev\openssl\out;C:\dev\openssl;C:\dev\cmake\bin;%PATH%
Start a new command shell (run cmd.exe) and
C: CD \dev prep.bat
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.
Using your computer while compiling
Compilation is a almost 100% CPU bound job. The windows task switcher doesn't really understand that this isn't really an interactive application, and hence will happily make your entire desktop quite laggy just to gain 1% on the compile time. It is therefore recommended to open your task manager (Ctrl-Alt-Del), switch to Processes, locate cmd.exe, rightclick, Set Priority, BelowNormal. And answer Yes. Doing so will make sure your interactive things get priority. Note, however, that if you do other 100% cpu bound things (like play resource-intensive games), compilation will halt until you're done.
TortoiseSVN
Download the most recent version of TortoiseSVN at http://tortoisesvn.net/downloads and install it. The defaults are fine.
Download Mumble SVN
Open c:\dev, rightclick and SVN Checkout...
Repository is
https://mumble.svn.sourceforge.net/svnroot/mumble/trunk
checkout to C:\dev\mumble\
MinGW
Create a directory c:\dev\MinGW
Download the following files:
- http://downloads.sourceforge.net/tdm-gcc/gcc-4.2.1-tdm-2-core-1.7z
- http://downloads.sourceforge.net/tdm-gcc/gcc-4.2.1-tdm-2-g++-1.7z
- http://prdownloads.sf.net/mingw/gdb-6.6.tar.bz2?download
- http://prdownloads.sf.net/gnuwin32/patch-2.5.9-7-bin.zip?download
- http://prdownloads.sf.net/mingw/binutils-2.17.50-20060824-1.tar.gz?download
- http://prdownloads.sf.net/mingw/w32api-3.10.tar.gz?download
- http://prdownloads.sf.net/mingw/mingw-runtime-3.13.tar.gz?download
- http://prdownloads.sf.net/mingw/mingw32-make-3.81-2.tar.gz?download
and unzip them all to the C:\dev\MinGW directory.
cd \dev\MinGW\bin copy mingw32-make.exe make.exe
Boost
Download http://prdownloads.sf.net/boost/boost_1_33_1.zip?download and http://prdownloads.sf.net/boost/boost-jam-3.1.13-1-ntx86.zip?download and unzip both to C:\dev\
cd \dev\boost_1_33_1 copy ..\boost-jam-3.1.13-1-ntx86\bjam.exe bjam -s"TOOLS=mingw" --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_33_1 and boost-jam directories. If you get the warning, that some targets were skipped or failed, it can be ignored for our purposes.
Microsoft Speech SDK
Go to http://www.microsoft.com/speech/speech2007/downloads.mspx and enter the link SAPI 5.1 SDK. A bit down on the following page is a download button for SpeechSDK51.exe. Download and install it to C:\dev\SpeechSDK
Microsoft DirectX SDK
Go to http://msdn.microsoft.com/directx/sdk/ and download the latest SDK. Install it to c:\dev\DXSDK\
WinDBUS
Download http://www.cmake.org/files/v2.4/cmake-2.4.7-win32-x86.zip 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
Run this command:
cd \dev\windbus patch -p0 < DBus-win32.patch
Now, you'll need to edit some of the files.
Edit windbus\dbus\dbus-spawn-win.c. On line 231, change
sitter->end_sync_event = NULL;
to
sitter->start_sync_event = NULL;
Edit windbus\dbus\dbus-sysdeps-win.c. On line 3019, change
if(CreateProcessA(dbus_exe_path, dbus_args, NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi))
to
if(CreateProcessA(dbus_exe_path, dbus_args, NULL, NULL, FALSE, CREATE_NO_WINDOW, NULL, NULL, &si, &pi))
... and then finally, run these commands:
cd \dev mkdir windbus-build cd windbus-build cmake -DDBUS_DISABLE_ASSERTS=ON -DDBUS_BUILD_TESTS=OFF -DDBUS_ENABLE_VERBOSE_MODE=OFF -DCMAKE_BUILD_TYPE=Release -DDBUS_INSTALL_SYSTEM_LIBS=ON -G "MinGW Makefiles" c:\dev\windbus\cmake make make install
Incase you get an error message licke this:
Please set the following variables: libxml2-include-dir (advanced) libxml2-libraries (advanced)
you need to install libxml and most likely libiconv.
http://downloads.sourceforge.net/gnuwin32/libxml2-2.4.12-1-lib.zip http://downloads.sourceforge.net/gnuwin32/libiconv-1.9.2-1-bin.zip
Extract both files to c:\<Program Files>\win32libs.
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)
OpenSSL
Download the latest OpenSSL source, unpack it to c:\dev\openssl
Download and install ActivePerl.
Open a new shell (so the path is correct)
cd \dev prep cd openssl ms\mingw32
Qt
Download ftp://ftp.trolltech.com/qt/source/qt-win-opensource-src-4.3.1.zip and unzip to C:\dev. Rename the directory from qt-win-opensource-src-4.3.1 to Qt4.3.1
Go to C:\dev\Qt4.3.1\mkspecs\win32-g++ and open the file qmake.conf. Change the following lines:
QMAKE_CFLAGS_RELEASE = -O2 QMAKE_CFLAGS_DEBUG = -g
into
QMAKE_CFLAGS_RELEASE = -O2 -march=pentium3 -mtune=generic -mmmx -msse QMAKE_CFLAGS_DEBUG = -O2 -fno-inline -g -march=pentium3 -mtune=generic -mmmx -msse
This will enable MMX and SSE instructions, and will also make sure Qt is tuned for modern architectures. It will also remove the exception threading support, which removes a few runtime dependencies.
So far, so good. However, in order to use SSE in threads, we'll need to make sure the thread stack is aligned, something neither the Windows runtime, the MinGW runtime or Qt does for us. So we'll hack this into Qt by fudging it's thread creation.
Open C:\dev\Qt4.3.1\src\corelib\thread\qthread_win.cpp in an editor. Locate the line which says
void QThread::start(Priority priority)
before this line, enter the following:
static unsigned int __attribute__((noinline, stdcall)) f_prime (void *p) { return QThreadPrivate::start(p); } unsigned int __attribute__ ((stdcall)) QThreadStackAligned (void *p) { (void)__builtin_return_address(1); // to force call frame asm volatile ("andl $-16,%%esp" ::: "%esp"); return f_prime (p); }
then, inside the ::start() function, change the line
d->handle = (Qt::HANDLE) _beginthreadex(NULL, d->stackSize, QThreadPrivate::start, this, CREATE_SUSPENDED, &(d->id));
to read
d->handle = (Qt::HANDLE) _beginthreadex(NULL, d->stackSize, QThreadStackAligned, this, CREATE_SUSPENDED, &(d->id));
In C:\dev\Qt4.3.1\tools\qdbus\src\src.pro change
CONFIG(debug, debug|release):LIBS += -ldbus-1d else:LIBS += -ldbus-1
to
LIBS += -ldbus-1
Also, go into C:\dev\Qt4.31\tools\qdbus\tools\qdbusviewer\images and copy dbusviewer.ico to qdbusviewer.ico.
then it's time to compile Qt
cd \dev\Qt4.3.1 configure -debug-and-release -qt-sql-sqlite -no-qt3support -no-exceptions -qt-zlib -qt-libpng -qt-libjpeg -openssl -qdbus -I c:\dev\openssl\outinc -L c:\dev\openssl\out -I c:\dev\dbus\include -L c:\dev\dbus\lib make
This will also take quite a while.
Building Mumble and Murmur
Once all of the above is done... Open C:\dev\mumble\src\mumble\mumble.pro 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 make release instead, which will result in a much smaller binary with fewer dependencies.
cd \dev\mumble qmake make clean make
