I have not tried a mixed platform approach like that, but it seems to me that it should work.  The result of your linux build will be static vtk libraries, vtk*.a, and static ves libraries libves.a and libkiwi.a, and headers for kiwi, ves, and vtk.  You may not need to include any vtk headers in your app at all, you probably only need to work with headers from src/ves and src/kiwi.<br>

<br>Take a look at Apps/Android/KiwiViewer/jni.  You'll see there is a single cpp file.  That file is compiled and linked against ves & vtk to generate the android jni library which will be part of your android APK.  We use cmake to compile this single cpp file, but you could instead write a very simple Android.mk makefile and do that compiling on your Windows environment.<br>

<div>Hi,</div>
<div>    Thanks for the prompt reply. We indeed are getting into more problems using cygwin. </div>
<div> </div>
<div>We are now going to follow these steps:</div>
<div>1. Build VES (and the dependencies) on Linux (Ubuntu 10.04). This should also generate an Eclips project.</div>
<div>2. Use the generated Eclips project in windows environment to develop our own android application on top of VES (kiwiviewer).</div>
<div> </div>
<div>Do you see any problems with these ?</div>

<br>For me, not knowing anything about cygwin, the first thing I would try is what the cmake output suggests, set CMAKE_LEGACY_CYGWIN_WIN32=1  But maybe that will not help.  I have to warn you that cygwin is an unsupported build environment for VES.  Is it possible to use Linux (perhaps with Virtualbox on Windows) instead? <br>
