Jogl_cg can't load cg or cggl library on system64.

jetlee01
I have wrote some cg examples using jogl_cg, they work well on 32-bit system of windows 7, but they can't work on the 64-bit system. And it always throw RuntimeException: Couln't load native Cg or CgGL library, at com.jogamp.opengl.cg.CgGL.<clinit>(CgGL.java:6581). Both of the two computers have same video card(GT750ti) and have installed Cg library. I don't kown why. Sorry my bad English.

Hi

Which version of JOGL do you use? Please post the full stack trace.

I use the latest version of jogl. I enable the debug of NativeLibray through the System.setProperty("jogamp.debug.NativeLibrary", "true");
The printed logs:

Please check whether the required native libraries are in the JARs containing the native libraries whose names contain "-natives-".

Re: Jogl_cg can't load cg or cggl library on system64.

Not that, I have included all the native libraries in my project.
Maybe I found the reason why it can't load the cg.dll or cggl.dll. I tried to load cg.dll directly using the "System.load("Cg.dll")" method, and then the jvm throw a UnsatisfiedLinkError: Can't load IA 32-bit .dll on a AMD 64-bit platform. It means the Cg.dll is 32-bit dll that can't load into the 64-bit jvm. So I have to run cg code on 32-bit machine. Am I right?

A 32-bit JVM on a 64-bit machine requires 32-bit binaries. A 64-bit JVM requires 64-bit binaries. You're wrong, you have to use the 64-bit binaries instead of the 32-bit binaries. You shouldn't have to load the native libraries by yourself. Use the JARs containing the native libraries or set the Java library path. I advise you to read this part of our user guide:
http://jogamp.org/jogl/doc/userguide/#automatednativelibraryloading
http://jogamp.org/jogl/doc/userguide/#traditionallibraryloading

Edit.: Let us know whether it works. There is nobody to maintain the Cg support of JOGL.

You're welcome. I have looked at the Ant scripts, CG native libraries seem to be excluded from jogl-all-natives-*.jar:
https://github.com/sgothel/jogl/blob/master/make/build.xml#L180
You need jogl-cg-natives-*.jar to make CG work. You might have to remove any conflicting DLL installed by another library.

Re: Jogl_cg can't load cg or cggl library on system64.

I had already contained the jogl-cg-natives-windows-amd64.jar and jogl-cg-natives-windows-i586.jar. The main problem is that the 64-bit jvm couldn't load the 32-bit Cg.dll library, and the Navidia doesn't provide any 64-bit cg.dll or cggl.dll for windows. When I call the cg native functions throw the jogl libraries, the first thing that jogl will to do is to load the gluegen-rt.dll into jvm, if this step success, it will load the Cg.dll and CgGL.dll, and finally load the jogl_cg.dll. Because my jvm is 64-bit, it needs 64-bit Cg libraries, they aren't match, so it would failed in the half way. So it nothing to do with the jogl-cg-natives-*.jar.

The only way to run the cg code through the jogl on 64-bit windows system is to use the 32-bit jvm instead of the 64-bit jvm.

I hope you to check whether the jogl-cg code can work on 64-bit windows system.

You can use the option "-d32" to run the 64-bit JVM in a 32-bit environment so that you don't need a 32-bit JVM. I'm not sure that it works but you can give it a try.

The JOGL CG code should work but as I wrote, it's unmaintained :s
