Setup environment

There are various useful environment variables to set in /etc/profile, relating to Zimbra build vars, Java/Ant vars, and P4 setup.

Install OS Packages for building

apt-get install build-essential libncurses5-dev libtool automake libltdl3-dev libperl-dev bison flex zlib1g-dev libpcre3 libpcre3-dev

Setup Java and ANT for building

** IGNORE THIS SECTION FOR NOW **
Although Zimbra now runs with Java 1.6, it still needs to be built with 1.5 so both must be downloaded. Download the latest 1.5 and 1.6 JDKs for Linux.  Note the versions are very specific - currently you must get 1.6.0_04 and 1.5.0_15.  You will have to go to Previous Releases, and Archive to get these:
Download Java 1.6
Download Java 1.5

We should end up with files similar to this:

jdk-1_5_0_15-linux-amd64.bin
jdk-1_5_0_15-linux-i586.bin
jdk-6u4-linux-i586.bin
jdk-6u4-linux-x64.bin
** END IGNORE **

Zimbra 5.0.6 has regressed to JDK1.5.0_15 for runtime, as there are unresolved bugs in JDK1.6.   So you don't have to download and unpack JDK1.6, only 1.5.0_15.
Download Java 1.5

Install JDK1.5:
sh jdk-1_5_0_15-linux-i586.bin
 or
sh jdk-1_5_0_15-linux-amd64.bin
mkdir -p /opt/build.zimbra
mv jdk1.5.0_15 /opt/build.zimbra
ln -s /opt/build.zimbra/jdk1.5.0_15/ /opt/build.zimbra/java
ln -s /opt/build.zimbra/java /usr/local/java
Install ANT:
wget http://mirror.public-internet.co.uk/ftp/apache/ant/binaries/apache-ant-1.7.0-bin.tar.gz
tar xf apache-ant-1.7.0-bin.tar.gz
mv apache-ant-1.7.0 /opt/build.zimbra/
ln -s /opt/build.zimbra/apache-ant-1.7.0 /opt/build.zimbra/ant

Create Users/Groups

Create zimbra user and group:
groupadd zimbra && useradd -g zimbra zimbra
mkdir -p /opt/zimbra
usermod -d /opt/zimbra zimbra
usermod -s /bin/bash zimbraCreate postfix user and group:
groupadd postdrop
groupadd postfix
useradd -g postfix postfix

Obtain Zimbra Source

First we need to download the p4 client binary from perforce:
mkdir -p /opt/build.zimbra/bin; cd /opt/build.zimbra/bin
wget http://www.perforce.com/downloads/perforce/r07.3/bin.linux26x86_64/p4
chmod a+rx p4Now synch the source (hint: don't do this right now, keep reading):
cd /opt/build.zimbra/source
/opt/build.zimbra/bin/p4 sync -f //depot/zcs/...This should currently synch three branches - FRANK, FRANKLIN and main. FRANK is 4.5.x, and main is HEAD - as we want to build a stable 5.0 release, we want FRANKLIN branch. If you're doing dev, probably better choosing main branch.

As the trees are quite large, you can (and probably should) opt for a single tree.  Here we're going for the current 5.0.x branch - FRANKLIN:
/opt/build.zimbra/bin/p4 sync -f //depot/zcs/FRANKLIN/..

UPDATE: Zimbra has created a special branch for 5.0.6.  So the actual command is:
/opt/build.zimbra/bin/p4 sync -f //depot/zcs/FRANKLIN-506/...
mv /home/public/p4/FRANKLIN-506 /home/public/p4/FRANKLIN

The synch goes into /home/public/p4/FRANKLIN.  When the synch is completed, move it into our build tree:
mv /home/public/p4/FRANKLIN /opt/build.zimbra/sourceNow download the patch with necessary fixes for Ubuntu 8.04:

And apply to the source:
