I have launch4j configure for my project. I used it back, when i developed on windowsXP, where it worked. Now i need it to build on mac as well:

My build.xml:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<project default="create-exe">

<property name="platform" value="win32"/>
<property name="launch4j.dir" location="${basedir}/tools/launch4j/" />

<include file="create-jar.xml" as="sub"/>

<target name="create-exe" depends = "sub.create-jar">
<launch4j configFile="launch4j-config.xml" />
<delete file="client.win32.jar"/>
</target>

<taskdef name="launch4j" classname="net.sf.launch4j.ant.Launch4jTask">
<classpath>
<pathelement path="tools/launch4j/launch4j.jar"/>
<pathelement path="tools/launch4j/lib/xstream.jar"/>
</classpath>
</taskdef>
</project>

I get the following output:

create-exe:
  Compiling resources

  18 RCDATA BEGIN "0\0" END

  104 RCDATA BEGIN "The registry refers to a nonexistent Java Runtime Environment installation or the runtime is corrupted.\0" END
  17 RCDATA BEGIN "true\0" END

When i add `bindir="tools/launch4j/bin"` to the launch4j-execution, ld and windres are found, and the output changes to:
