JOCL FAQ

How do I get the Source Code?
The project repository is located on github.

You can create a local copy/branch of the git repository, either anonymous:


 * git clone git://github.com/mbien/gluegen.git gluegen
 * git clone git://github.com/mbien/jocl.git jocl
 * git clone git://github.com/mbien/jocl-demos.git jocl-demos
 * git clone git://github.com/mbien/jogl.git jogl

or via SSH and your user credential, so you can easily push back your changes to the github server:


 * git clone git@github.com:username/gluegen.git gluegen
 * git clone git@github.com:username/jocl.git jocl
 * git clone git@github.com:username/jocl-demos.git jocl-demos
 * git clone git@github.com:username/jogl.git jogl

What are the Build Dependencies?
JOCL depends on GlueGen and JOGL

JDK6 and ANT 1.8 or later. JUnit tests require OpenCL capable hardware and OpenCL drivers.

I have all the Sourcecode, how do I build it?
Please refer to this HowTo

What files do I need at Runtime?
JOCL consists of two files: additionally you will have to provide optionally you might want to add JOGL if you want to do OpenGL - OpenCL interoperability
 * jocl.jar
 * and one system dependent native library (e.g libjocl.so or jocl.dll or ..).
 * gluegen-rt.jar
 * and the corresponding native library (e.g libgluegen-rt.so or gluegen.dll or ...)
 * see [/jogl/doc/deployment/JOGL-DEPLOYMENT.html JOGL deployment options]

How do I Get Started?

 * Short Introduction to JOCL
 * Hello JOCL
 * JOCL Demo Projects

Is it possible to run JOCL based app without JOGL?
Yes. JOCL is independent from JOGL and can be used without JOGL in the classpath. In fact you have to explicitly create a shared context from a existing JOGL context if you want to interoperate with OpenGL.

// creates a pure OpenCL context CLContext.create;

// creates a shared context. This context can be used to share memory with JOGL's OpenGL context CLGLContext.create(glContext);

Can I allocate a CLBuffer without allocating a java.nio.Buffer?
yes, just use the right context.createBuffer method.

Is jocl.org the same as JOCL?
no its not. Both are independent projects.
