compiler References in task

Hello-

I have the following build file and I'm not sure what I'm missing:

<project name="MyProj" default="build" basedir=".">
  <taskdef resource="cpptasks.tasks" classpath="./Tools/Ant/cpptasks.jar" />
  <typedef resource="cpptasks.types" classpath="./Tools/Ant/cpptasks.jar" />

  <compiler id="my-compiler" name="msvc">
    <defineset define="_DEBUG" />
  </compiler>

  <target name="build">
    <cc subsystem="console" outtype="executable" outfile="hello">
      <compiler refid="my-compiler" />
      <fileset dir="." includes="*.c" />
    </cc>
  </target>
</project>

When I try to run this, I get an error saying:
build.xml:12: my-compiler doesn't denote a ProcessorDef

This is my first attempt to factor out the compiler types, so thanks for
your patience :)

Or drop cpptasks.jar in ANT_HOME/lib, and use XML namespaces with the
auto-magic antlib:net.sf.antcontrib.cpptasks URI, which I bind to the
cc prefix. I can then do <cc:compiler>, <cc:linker>, <cc:cc>, etc...

That did it, thanks!

I ended up using the antlib.xml to get the definitions in the same import...

Thanks,

You need to make sure that they are loaded by the same classloader; 
giving them the same path doesnt guarantee this, and once in separate 
classloaders, the tasks cannot cast the reference to the types they expect.

<classpath id="cpptasks.classpath" path="./Tools/Ant/cpptasks.jar" />

<taskdef resource="cpptasks.tasks" classpathref="cpptasks.classpath"  />
<typedef resource="cpptasks.types" classpathref="cpptasks.classpath"  />

You need to make sure that they are loaded by the same classloader; 
giving them the same path doesnt guarantee this, and once in separate 
classloaders, the tasks cannot cast the reference to the types they expect.

<classpath id="cpptasks.classpath" path="./Tools/Ant/cpptasks.jar" />

<taskdef resource="cpptasks.tasks" classpathref="cpptasks.classpath"  />
<typedef resource="cpptasks.types" classpathref="cpptasks.classpath"  />
