Welcome to Ant/CppTasks.

First, the Ant list is not the right list to ask ;-)
CppTasks' list is the Ant-Contrib one. Check out the project page on SF.net.
I'm CC'ing the proper list.

The two lines above are fine.

> <taskdef name="cc" classname="net.sf.antcontrib.cpptasks.CCTask"/>
> <typedef name="linker" classname="net.sf.antcontrib.cpptasks.LinkerDef"/>
> <typedef name="compiler"
> classname="net.sf.antcontrib.cpptasks.CompilerDef"/>

These are not, since duplicate what the two first have done...

outfile's name is wrong. It shouldn't end in .o. It's supposed to be the
name of the library or executable to generate, and in addition, it should 
be the name without platform-specific extension. CppTasks will add the
proper extension (like .so or .dll, depending on the OS).

No need for a compiler or linker, you already specified it in <cc>.

I never put .h files to compile, you set an <includepath> to locate them.

> 		</fileset>
> 	</compiler>
> 	<linker name="gcc"></linker>

Again no need for a linker element here.

And finally, this means GCC in not in your Path. Do you really intend to
compile with GCC on Windows?

I'm afraid you have quite a bit ahead of you ;-) Good luck, --DD
