JOGL 32 vs. 64 bit libraries error

Question

I am new to JOGL. I use Eclipse and I imported JOGL jar and dll (yes, Windows OS). But, when I was searching for JOGL libraries, I downloaded 32 bit version. I have 64 bit OS, but since I can run 32 bit apps I thought it will still be more suitable. But compiler is complaining: Can't load IA 32-bit .dll on a AMD 64-bit platform

Well, first, I thought Java itself is NOT separated by architecture. Yes, I know I am using native libraries to link into Windows OpenGL interface (API), but I just want to include these code snippets into java bytecode, so why compiler cant let me use 32 bit ones? Thanks.

Answer 1

Since you have a 64-bit OS, you installed the 64-bit JVM. The 64-bit JVM cannot use the 32-bit DLLs, so you'll need to either download the 64-bit ones, or alternatively, install the 32-bit JVM on your system and set Eclipse to use that JVM instead.

Answer 2

64bit JVM cannot load 32bit libraries. You need to start 32b JVM to make it work (or get 64b dlls).
