Question

I’m trying out OpenNI for Kinect and got it to install and run sample code according to
this guide. But now, I want to modify the code and compile it and test it. However, I’m not sure how to compile and run on Linux. I found a guide here that does it for Windows, but can’t seem for the life of me to find anything for Linux.

I did try adapting the Windows code for Linux and tried

javac -cp ~/kinect/OpenNI/Samples/Bin/x86-Release/org.OpenNI.jar VersionInfo.java
java -cp ~/kinect/OpenNI/Samples/Bin/x86-Release/org.OpenNI.jar VersionInfo

but it gives me

Exception in thread "main" java.lang.NoClassDefFoundError: VersionInfo
Caused by: java.lang.ClassNotFoundException: VersionInfo

at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
Could not find the main class: VersionInfo. Program will exit.

Any ideas on how I can compile and run my java code onto the Kinect? If you know how to do it for the Samples in the OpenNI folder, that would be perfect.

Answer 1

Nevermind, figured it out. Turns out I needed to learn about make and Makefiles and how they’re used to compile .java files into a .jar.
