BuildingFreeBSD

Compatible FreeBSD Releases
I can only confirm that Murmur runs on the following FreeBSD releases. However, it should build and run on others just fine. Feel free to edit this to add more versions that you've had success with.


 * FreeBSD 7.1
 * FreeBSD 7.2
 * FreeBSD 8.0
 * FreeBSD 8.1
 * FreeBSD 8.2
 * FreeBSD 9.0
 * FreeBSD 9.1

Mumble Client
This is a placeholder. This guide is targeted towards Murmur from git at the moment. You should be able to install the Mumble client 1.2.3 from ports relatively pain-free:

cd /usr/ports/audio/mumble make install clean

Murmur from Ports
You can rather trivially install Murmur 1.2.3 from the ports tree:

cd /usr/ports/audio/murmur make install clean

The binary packages for Murmur have been updated to 1.2.3 on 8-stable and 9-current. So far all release packages are still 1.2.2 or earlier, so build from ports on those versions.

Grabbing sources from git
I put this part here because I got sick of going over to the Linux page every time I build Murmur on a new machine. If you haven't already installed git:

cd /usr/ports/devel/git make install clean

or for the impatient:

pkg_add -r git

Next, clone the entire repository:

git clone git://github.com/mumble-voip/mumble.git mumble cd mumble git submodule init git submodule update

Alternatively, you can fetch a zip file of the entire repository, without the need for git, like so:

cd ~ fetch https://github.com/mumble-voip/mumble/archive/master.zip unzip master.zip rm master.zip cd mumble-master

Install the dependencies
The following are the main dependencies required for building Murmur 1.2.x from git.


 * devel/boost (devel/boost-libs on 8.0+)
 * devel/ice
 * security/openssl (See notes below)
 * devel/protobuf
 * devel/qt4-corelib
 * devel/qt4-moc
 * net/qt4-network
 * devel/qmake4
 * devel/qt4-rcc
 * databases/qt4-mysql-plugin (See note below)
 * databases/qt4-sql
 * databases/qt4-sqlite-plugin
 * textproc/qt4-xml

If you want to include Bonjour support, include these deps as well:
 * net/avahi
 * net/avahi-qt4

security/openssl port: The port isn't required, however at the time of writing there's a rather nasty DoS in QSslSocket which is fixed by upgrading to OpenSSL 0.9.8o or 1.0.0a, neither of which are in base on any current release, but the latter of which is in security/openssl port at the time of writing. However, if you install this port, you'll need to rename /usr/lib/libssl.so to something else, because QT's runtime loader will grab the non-ports libssl and cause you all manner of grief.

databases/qt4-mysql-plugin port: The port is only required if you wish to use the QMYSQL driver.

Compilation
To build the server, Murmur:

qmake-qt4 CONFIG+=no-client CONFIG+=no-dbus CONFIG+=no-bonjour main.pro make release

Note, I currently don't use CONFIG+=optimize because I'm building on 7.2 and running the binary on 7.1. I have no idea what possible consequences could come of that. I would not expect anything, but I'm just being on the safe side.

Run Murmur
I actually prefer to build Murmur in a VM and send builds up to the production server. To view murmur's dynamic dependencies for your system and configuration, simply run. In case you're wondering, here are the run deps (without Bonjour support):

libprotobuf.so.7 => /usr/local/lib/libprotobuf.so.7 (0x800a5e000) libcrypto.so.6 => /lib/libcrypto.so.6 (0x800d84000) libIce.so.34 => /usr/local/lib/libIce.so.34 (0x801122000) libIceUtil.so.34 => /usr/local/lib/libIceUtil.so.34 (0x80166b000) libQtSql.so.4 => /usr/local/lib/qt4/libQtSql.so.4 (0x8018b9000) libQtXml.so.4 => /usr/local/lib/qt4/libQtXml.so.4 (0x801b00000) libQtNetwork.so.4 => /usr/local/lib/qt4/libQtNetwork.so.4 (0x801d4e000) libQtCore.so.4 => /usr/local/lib/qt4/libQtCore.so.4 (0x8020df000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x802610000) libm.so.5 => /lib/libm.so.5 (0x80290b000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x802b29000) libthr.so.3 => /lib/libthr.so.3 (0x802d36000) libc.so.7 => /lib/libc.so.7 (0x802f58000) libz.so.6 => /lib/libz.so.6 (0x8032a2000) libbz2.so.4 => /usr/lib/libbz2.so.4 (0x8034b7000) libgthread-2.0.so.0 => /usr/local/lib/libgthread-2.0.so.0 (0x8036c8000) libglib-2.0.so.0 => /usr/local/lib/libglib-2.0.so.0 (0x8038cc000) libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x803bae000) libintl.so.9 => /usr/local/lib/libintl.so.9 (0x803eaa000) libpcre.so.3 => /usr/local/lib/libpcre.so.3 (0x8040b4000)

No SSL ciphers of at least 128 bit found
It seems to me like there's a problem with QT on FreeBSD. When you have OpenSSL from ports, and the ABI is different from the one in base (say, OpenSSL 1.0 from ports, 0.9.8 from base) QT does some weird things. It'll load half the library from ports (the part that ld(1) loads), then QT comes along and loads it's share from base. The result is lots of unexpected behavior, with "No SSL ciphers of at least 128 bit found" being the most common.

The dirty fix if you have root access is simply to rename the base libssl.so to something so that QT's loader doesn't find it, and looks in /usr/local/lib instead:


 * 1) mv /usr/lib/libssl.so /usr/lib/libssl.so.old

No certificates could be verified
Note that recent versions of OpenSSL will verify the server's own certificate at the start of a TLS session, so you might get an error like "No certificates could be verified". Older versions of Murmur didn't have the FreeBSD cert store in the search path, so you needed to tell it where to find it:

qmake-qt4 CONFIG+=no-client CONFIG+=no-dbus CONFIG+=no-bonjour \ DEFINES+="SYSTEM_CA_BUNDLE=/usr/local/share/certs/ca-root-nss.crt" main.pro

slice2cpp errors
If you get errors about slice2cpp or Ice/SliceChecksumDict.ice, you must edit src/murmur/murmur.pro and add another include path (/usr/local/share/Ice) to the slice2cpp line (#72 at time of writing), like so:

slice2cpp --checksum -I/usr/local/share/Ice ....

... or you could just symlink that directory to one of the directories the Makefile searches already, or use patch #3026518.

This error has been fixed for a while.

alloca.h missing
When building 1.1.8 or earlier, build fails because of a missing alloca.h header. On FreeBSD, alloca is declared in stdlib.h, so it's safe to comment the line out (in src/murmur/murmur_pch.h). This has been fixed in git for quite some time, and is apparently fixed in the port of 1.1.8.

Requesting crypt-nonce resync
On 64-bit FreeBSD installations, Murmur 1.1.x and early 1.2 builds would fail, spamming "Requesting crypt-nonce resync" messages in the log, as reported here and here.

Crypto was broken on amd64 (and presumably others), however it's fixed in git. If you're trying to build a 1.1.8 server from source, this patch might help.

This was fixed in ports (ports/139384), so if you're building from ports, make sure your ports tree is up to date.
