= CentOS 5.4 Compilation Guide =

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

== Build Environment Setup ==

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
}}}

If you are also performing an FDO 3.5 build on the same machine, the following packages may also needed:
{{{
yum install python-devel
yum install mysql mysql-devel
yum install unixODBC unixODBC-devel
}}}

Download Java SE JDK 6 from Sun and install it.  Then export JAVA_HOME from .bash_profile
{{{
JAVA_HOME=/usr/java/latest
export JAVA_HOME
}}}

== Build Process ==

1. Checkout the source from Subversion
{{{
svn export http://svn.osgeo.org/mapguide/trunk/MgDev mgdev
svn export http://svn.osgeo.org/metacrs/csmap/trunk/CsMapDev mgdev/Oem/CsMap
svn export http://svn.osgeo.org/fusion/trunk mgdev/Oem/fusion
}}}
(I think that instead of the above, you should use:
{{{
svn checkout http://svn.osgeo.org/mapguide/trunk/MgDev mgdev
}}}
It may be slower, but it will guarantee that the external references that you get are correct even if they get changed. Tom)

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.
