file: jogl-src-1.1b10.zip
I know nothing about C/C++ but still just downloaded jogl sources first time I took a quick look of the native side. Well, I know even less native code now.
The given zip file has a lot of includes .h files, that ok. But then .c source codes I only could find few, just too few to be real.
BufferUtils.c, InternalBufferUtils.c, JAWT_DrawingSurfaceInfo.c
I am missing something now for sure. lwjgl-src.zip has soo many native code files that jogl-src.zip is not complete.
