Now I am trying to execute this in UNIX, facing some issues there..

1) Downloaded 'apache-ant-1.6.5-bin.tar.gz' and extracted into my home dir

2) Modified the ant script as follows

ANT_HOME=<home_dir>/apache-ant-1.6.5
JAVA_HOME=<java_home>
PATH=${PATH}:${ANT_HOME}/bin:${JAVA_HOME}/bin:$/usr/local/bin/cc  (/usr/blocal/bin/cc
is path to C++ compiler)
export CLASSPATH ANT_HOME JAVA_HOME

3) Added the above build.xml and hello.cpp file

4) Executed using the following

-> sh ant -verbose -noclasspath
Apache Ant version 1.6.5 compiled on June 2 2005
Buildfile: build.xml
Detected OS: SunOS

Build sequence for target(s) `hello' is [cpptasks, init, hello]

Can somebody tell me from where does it pick up this path?
"dropping <home_dir>/apache-ant-1.6.5/bin/lib from path as it doesn't exist"

And is this again some issue with the C++ compiler/linker?

What could be the issue and resolution?

Thanks,
Sharad.
