= CentOS 5.4 Compilation Guide =

'''''These compilation steps are a work in progress.'''''

== Build Environment Setup ==

1. CentOS 5.4 uses GCC 4.1 as its native compiler so !MapGuide 2.2 does compile cleanly on CentOS 5.4.  The following rpms are required (list may not be complete):
{{{
yum install gcc gcc-c++ autoconf automake automake17 libtool bison
yum install libjpeg-devel libpng-devel fontconfig-devel freetype-devel
yum install libxml2-devel expat-devel curl-devel libxslt-devel openldap-devel
yum install subversion ant xml-commons-apis
}}}
2. Download Java SE JDK 6 from Sun and install to /usr/local/.  Suppose the installation is under /usr/local/jdk1.6.0_21, follow below steps to export JAVA_HOME from ''.bash_profile'' or ''.bashrc''
{{{
cd /usr/local
ln -s jdk1.6.0_21 java
}}}
Open ''.bash_profile'' or ''.bashrc'' in an editor, add the following lines
{{{
JAVA_HOME=/usr/local/java
export JAVA_HOME
export PATH=$PATH:$JAVA_HOME/bin:
}}}
3. Download FD0 3.5.0 CR1 Linux Binary tarball from [http://fdo.osgeo.org/content/downloads/ Here], and follow the steps to install FDO to /usr/local/
{{{
cd /usr/local
mkdir fdo-3.5.0
cd fdo-3.5.0
tar -xvvzf fdosdk-rhel5-3.5.0.tar.gz
}}}
  
== Build Process ==

1. Checkout the source from Subversion
{{{
svn checkout http://svn.osgeo.org/mapguide/branches/2.2/MgDev mgdev
OR 
svn export http://svn.osgeo.org/mapguide/branches/2.2/MgDev mgdev
}}}

2. Build the Oem tree
{{{
cd mgdev
./build_oem.sh
pushd Oem/fusion
ant prepare
ant compress
popd
pushd Oem/LinuxApt
./build_apt.sh
popd
}}}
3. Build !MapGuide
{{{
aclocal
libtoolize --force
automake --add-missing --copy
autoconf
./configure --enable-optimized
make
make install
}}}

You should now have a copy of !MapGuide 2.2 built and installed to /usr/local/mapguideopensource.
