needing help with setup...

OpenGL Development JOGL Development
#1

Well, I went here : http://www.stud.ntnu.no/~johanno/appletviewer.jsp?task=tutorials
downloaded and upgraded my JVM to get the applets working, and now my Eclipse setup is screwed. I’ve gone through every step now since last night many times, and even deleted / remade the whole project. sigh

I know, I know, I’m learning the hard way, which is for the best.

Now, here is the offending error :

java.lang.UnsatisfiedLinkError: dispatch_wglGetExtensionsStringARB
at net.java.games.jogl.impl.windows.WindowsGLImpl.dispatch_wglGetExtensionsStringARB(Native Method)
( followed by another 20 of same )

This is rather excruciating! I’m still getting my head around Jars and all that, so if someone could please advise how to pursuade Eclipse to make this connection, I would be most grateful. I suspect this has to do with the DLL’s ( which seem to be in the right place ).

For more info on my problem, I posted more details here also :

I use NetBeans, not Eclipse. But I don’t have any of the issues you’re describing.

You say the DLLs seem to be in the right place. What place is that?

I dump jogl.jar, jogl.dll and jogl_cg.dll into my lib/etc directories in both my JDK and JRE directories.

That might not be a good idea. I tend to avoid all kind of unnecessary mess in the JRE/JDK library directories. Thus, I’ll add the required libraries to each project separately, which of course leads to some duplication of jar/dll files, but can be controlled more accurately (per project, that is). This way you don’t end up with problems if any of the projects should require a specific version of a library (say JOGL).

#5

My final deployment is webstart, which does basically the same thing as you describe. I agree with the philosophy on an installation.

But I prefer to have a central location where the files are kept so that I can upgrade once while I’m developing. Alternatively, I could use a classpath, but again it would have to be updated each time. Or I could make use of symbolic links. That’s the route I would take under UNIX, but I’m stuck in the Windows world for the moment.

#6

well, curses. I’m back in business after a complete re-install of JSDK/RE / Eclipse ~ but that did not solve the problem. Oh no, the problem was that I had at some point downloaded a newer ‘beta’ jogl.jar… I got an older one, and everything is great again. Don’t you all just love software development! Actually I do, but these moments are a pretty high price.
