Yes you're absolutely right. I had missed the "environment" attribute in
the documentation...
So for everyone interested:
For adding the C++ compile/link step to a JNI project using ant unter
Windows works like this:
1) add an environment property to the "init"-target (if you haven't done
so already):
<target name="init">
...
<property environment="env"/>
...
</target>
2) add a "cppcompile" task after the "headergen" task (the one that
generates the c++-headers with javah)
<target depends="init,headergen" description="Compile C++ dll."
name="cppcompile">
<!-- you must set the PATH to ${basedir}\..\ressources otherwise
the ressources can't be found -->
<apply executable="cl" dest="${basedir}/../ressources"
parallel="false" failonerror="true">
<arg line="-I${env.JavaPath}\include
-I${env.JavaPath}\include\win32"/>
<arg line="-LD"/>
<fileset dir="${basedir}">
<include name="**/*.c"/>
<include name="**/*.cpp"/>
</fileset>
<mapper type="glob" from="*.cpp" to="*.dll"/>
</apply>
</target>
Thanks Vlad!
