Installing Bonjour for *nix Users at Construct

Every time Ubuntu’s Synaptic Package Manager updates the Avahi layer for Bonjour support it stomps on my Apple Bonjour install and breaks my Construct install. My guess is that the update puts Avahi first in the list of Bonjours to run when Construct starts. So I get this error:

*** WARNING *** The programme ‘java’ uses the Apple Bonjour compatiblity layer of Avahi.

*** WARNING *** Please fix your application to use the native API of Avahi!

*** WARNING *** For more information see

*** WARNING *** The programme ‘java’ called ‘DNSServiceQueryRecord()’ which is not supported (or only supported partially) in the Apple Bonjour compatiblity layer of Avahi.

*** WARNING *** Please fix your application to use the native API of Avahi!

*** WARNING *** For more information see

One way to address this is just to turn off the Avahi warning. Set an environmental variable list this export AVAHI_COMPAT_NOWARN=1 This isn’t a fix though it is just hiding the warning.

The best I have figured out so far is just to reinstall Bonjour:

Instructions for Installing Apple’s Bonjour on *nix

Download the latest version of the Bonjour source code here.
Decompress the downloaded archive
cd to the mDNSPosix directory below the mDNSResponder-xxx directory (where xxx is the Bonjour version number).
Edit Makefile and change line JDK = /usr/jdk to make it point at your Java installation (e.g., /usr/lib/jvm/java-6-sun)
Type sudo make os=linux Java
Type sudo make os=linux install — if you have problems with this, see below. Most likely you will need to install a specific version of gcc
Copy the java specific files to your jre lib’s ext directory (cp build/prod/* /path/to/jre/lib/ext/)
Open up /etc/nsswitch.conf and ensure that the ‘mdns’ switch appears on the “hosts:” line. My “hosts:” line looks like this:

hosts:          files dns mdns

Remember, whenever you use a new jre, make sure to include dns_sd.jar (Bonjour JAR file) in your jre/lib/ext directory

Problems with the install

Problems with `stdlib.h`

Lorcan had some problems with this install on Ubuntu (Edgy). He says: when running sudo make os=linux Java I got a lot of errors, starting with ../mDNSShared/dnssd_clientlib.c:71:20: error: stdlib.h: No such file or directory.

I installed the libc6-dev package. When I tried again everything worked fine

Problems with `__stack_chk_fail_local`

I had some major problems with this install on Ubuntu (Edgy), specifically when using gcc4.1 (to find out which version of gcc you are using type gcc --version).

Solution:
If the version of gcc is not 4.0.x Follow these instructions (EXACTLY!!!) to correct the problem:

Ensure that gcc version 4.0.x is installed. This is a little tricky as the synaptic package manager stopped supporting this version of gcc since edgy. You’ll have to download the following packages: gcc-4.0-base, cpp-4.0 , gcc-4.0
Open the terminal and cd to where you saved the package.
Do the following for each of the three packages: dpkg -i PACKAGE.deb Install them in the same order the are above. gcc base first, then cpp, then gcc — This should put gcc-4.0 into your /usr/bin directory.
cd /usr/bin
sudo mv gcc gcc-backup
sudo ln -s gcc-4.0 gcc

Now completely rerun the instructions above (at the top of this page) to install Bonjour (you must completely rerun them from step 2). When installation is complete continue these instructions.
