BuildingMacOSX

Note: This guide is written for the current git HEAD (Mumble version 1.2.X). If you want instructions for 1.1.X, please check the history for this page.

Introduction

This guide describes the method to get a fully working and redistributable version of Mumble and Murmur that uses the Cocoa version of Qt 4. This build will work on both Intel and PowerPC Macs on Mac OS X 10.5 (Leopard).

If you don't want a universal build, you can achieve this by passing CONFIG+='no-universal' to qmake.

Dependencies

To build Mumble you will need:

• Mac OS X 10.5 (Leopard)
• XCode (http://developer.apple.com/tools/xcode/, or from your Mac OS X install disks)
• Git (http://www.git-scm.org/)
• pkg-config (http://pkg-config.freedesktop.org/)
• DBus (http://dbus.freedesktop.org/)
• Qt 4.5.2 (http://www.qtsoftware.com/developer/downloads/qt/mac)
• Boost (http://www.boost.org/)
• PortAudio (http://www.portaudio.com/)
• libsoundfile (http://www.mega-nerd.com/libsndfile/)
• Protocol Buffers (http://code.google.com/p/protobuf/)
• Berkeley DB (http://www.oracle.com/technology/products/berkeley-db/index.html) (Murmur only)
• mcpp (http://www.sourceforge.net/projects/mcpp/) (Murmur only)
• ZeroC Ice (http://www.zeroc.com) (Murmur only)

echo Now in Mumble 1.2 build environment

Remember to source the above script before doing any of the steps listed below.

Installing or building pkg-config

This is just a build tool, so you do not have to build it as universal binary.

If you have MacPorts installed, you probably already have pkg-config as well. If not, you can install it by doing

sudo port install pkgconfig

In case you want to compile it yourself, you'll have to download and unpack pkg-config.

sudo mkdir /usr/lib/pkgconfig (choose a path you like)
export PKG_CONFIG_PATH=/usr/lib/pkgconfig
./configure && make && sudo make install 

To make the path permanent add the following line to your ~/.profile file:

export PKG_CONFIG_PATH=/usr/lib/pkgconfig

Also add a path entry to the pkg-config binary to this file:

export PATH=$PATH:/usr/local/bin

Installing or getting Git

To grab a copy of Mumble, you need Git.

You have three options:

• Build it yourself.
• Install it via MacPorts: port install git-core
• Fetch the git-osx-installer package from Google Code: http://code.google.com/p/git-osx-installer/downloads/list?can=3

Building DBus

Grab the latest release of DBus from http://dbus.freedesktop.org/. As of this writing that is version 1.2.12.

Unpack it, and build it:

./configure --prefix=/opt/mumble/dbus/ --without-x --with-xml=expat --disable-dependency-tracking
make
make install

Building Qt

Download an unpack Qt.

unset CFLAGS
unset CXXFLAGS
unset LDFLAGS
./configure -debug-and-release -no-exceptions -universal -cocoa -qt-sql-sqlite -system-zlib -qt-gif -qt-libpng -qt-libjpeg -qdbus -webkit -phonon -phonon-backend -no-qt3support -sdk $OSX_SDK -prefix $MUMBLE_PREFIX/qt- framework-4.5.2/ -opensource
make
sudo make install
export CFLAGS=$OSX_CFLAGS
export CXXFLAGS=$OSX_CFLAGS
export LDFLAGS=$OSX_LDFLAGS

Installing Boost

As Mumble only uses some Boost headers you do not have to build Boost from scratch - you just need to unpack it.

It is advisible to unpack Boost to $MUMBLE_PREFIX/include/, so the Boost headers will be available in $MUMBLE_PREFIX/include/boost-1_39_1/, since Mumble will look for the headers in this place by default.

Building PortAudio

Download and extract the latest nightly PortAudio snapshot:

http://portaudio.com/archives/pa_snapshot.tar.gz

Build and install:

wget http://www.scorpius-project.org/mumble-stuff/portaudio-fix.patch
patch -p1 < portaudio-fix.patch
./configure --disable-mac-universal --disable-dependency-tracking --prefix=$MUMBLE_PREFIX
make
sudo make install

Building libsndfile

Grab the latest version. Build:

export CFLAGS="-isysroot /Developer/SDKs/MacOSX10.5.sdk -arch ppc"
export CXXFLAGS=$CFLAGS
export LDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.5.sdk -arch ppc"
./configure --prefix=$(pwd)/ppc-root/
make
make install
make distclean
export CFLAGS="-isysroot /Developer/SDKs/MacOSX10.5.sdk -arch i386"
export CXXFLAGS=$CFLAGS
export LDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.5.sdk -arch i386"
./configure --prefix=$MUMBLE_PREFIX
make
sudomake install
lipo -create -arch ppc ppc-root/lib/libsndfile.1.dylib -arch i386 $MUMBLE_PREFIX/lib/libsndfile.1.dylib -output $MUMBLE_PREFIX/lib/libsndfile.1.dylib
export CFLAGS=$OSX_CFLAGS
export CXXFLAGS=$CFLAGS
export LDFLAGS=$OSX_LDFLAGS

Building Protocol Buffers

Grab the latest version of Protocol Buffers from its Google Code project: http://code.google.com/p/protobuf/. As of this writing, that is version 2.0.3. Direct link: http://protobuf.googlecode.com/files/protobuf-2.0.3.tar.bz2

Build and install it:

./configure --disable-dependency-tracking --prefix=$MUMBLE_PREFIX
make
sudo make install

Logitech LCD SDK (optional)

Grab it, install it. Build it:

sudo mkdir -p $MUMBLE_PREFIX/lglcd-sdk/
sudo tar -zxvf /Applications/Logitech/GamePanel\ Software/LCD\ Manager/LCDSDK/LCDSDK.tgz -C $MUMBLE_PREFIX/lglcd-sdk/
sudo chmod -vR +r $MUMBLE_PREFIX/lglcd-sdk/

libmcpp

Grab it. Build it:

./configure --disable-dependency-tracking --prefix=$MUMBLE_PREFIX --enable-mcpplib
make
sudo make install

Berkeley DB

Grab it. Build it:

for i in 1 2 3 4; do wget http://www.oracle.com/technology/products/berkeley-db/db/update/4.7.25/patch.4.7.25.$i; done
for i in 1 2 3; do patch -p0 < patch.4.7.25.$i; done
patch -p1 < patch.4.7.25.4
cd build_unix
../dist/configure --disable-dependency-tracking --prefix=$MUMBLE_PREFIX --enable-cxx

ZeroC Ice

Grab it. Build it:

make prefix=$ICE_PREFIX embedded_runpath_prefix=$ICE_PREFIX OPTIMIZE=yes CXX="$CXX $OSX_CFLAGS" CC="$CC $OSX_CFLAGS" DB_HOME=$MUMBLE_PREFIX MCPP_HOME=$MUMBLE_PREFIX
sudo make prefix=$ICE_PREFIX embedded_runpath_prefix=$ICE_PREFIX OPTIMIZE=yes CXX="$CXX $OSX_CFLAGS" CC="$CC $OSX_CFLAGS" DB_HOME=$MUMBLE_PREFIX MCPP_HOME=$MUMBLE_PREFIX install

Building Mumble

Fetch the Mumble source from Git:

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

To build the client, execute:

qmake main.pro CONFIG+='release'
make

If everything went well, you should now have a Mumble.app application bundle in the release directory of the root of the source tree.

Distributing Mumble

If you wish to create a proper redistributable Mumble application bundle, please refer to the osxdist.sh script in the scripts directory. This will help you clean up your application bundle, include the needed dependencies, resources etc., and create a compressed disk image - ready to redistribute!

The script expects you to be in the root of the source tree. After executing, it will spit out a .dmg of your Mumble build in the release folder.

Please note that the script currently is tuned for creating real redistributable versions of Mumble, and as such only works on universal (x86, ppc) release builds!
