compiling VTK using Xcode

[ilantal]

I have a Mac Air OSX 10.8.2 with Xcode 4.5.2 which I am trying to wrap VTK so I can use it within a Java program. This works on both Linux and Windows and I want to extend it to the Mac.
I use CMake 2.8.9 to Configure and Generate. I get the message that Filter ZLIB is ON which I assume is perfectly OK. Then I use Xcode on VTK.xcodeproj which tries to compile the project. I get errors like
Run custom shell script 'CMake PostBuild Rules' where CMakeScripts/vtkWrapJava_postBuildPhase.makeDebug doesn't exist.
This is indeed correct, so such file by that name exists. So how do I get around the problem? How do I tell it that I don't want a post build?

It seems like this is somehow connected to CMake, but I don't see anything obvious in CMake about a post build phase. CMake seems to have dozens of options so I could easily have one of them set incorrectly. None of them have any obvious connection to a post build phase.
Thanks,
Ilan

You using build instructions here? If you are, the problem's almost certainly these two lines right here:

CMAKE_OSX_ARCHITECTURES:STRING=ppc;i386
export MACOSX_DEPLOYMENT_TARGET=10.4

Neither of those work properly on 10.8. Use instead:

CMAKE_OSX_ARCHITECTURES:STRING=i386
export MACOSX_DEPLOYMENT_TARGET=10.8

Also, VTK and Java 7 don't yet get along - use Java 6 instead.

In the final analysis I couldn't get Xcode to compile properly the Java wrap. Instead I used ccmake and the Unix make and make install. That at least compiled properly.
As you pointed out Java 7 and VTK don't exactly live together in peace. I got a message saying it was trying to retrograde the 7 back to 6, but the retrograde failed.
What I need is some way to tell the VTK make to use 6 and not 7.

Set JAVA_HOME to where Java 6 lives. That should help. To do that:

export JAVA_HOME=/path/to/JDK6/Home

Thank you wrldwzrd89, that was a good idea:

The problem however is still there. I wonder if it might be because your idea set the path to java, but javac is being used to compile. Is there some sort of "export JAVAC_HOME=/path...."?

Nope. JAVA_HOME refers to the home folder of the JDK - where javac lives (and java, in the JDK's private JRE).

For me, the correct JAVA_HOME value is:

/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
