In the current DRI implementation it is required that the - * symbols in libGL.so.1.2 be globally visible to be accessible from - * other libraries that are dynamically loaded by the implementation. - * Applications may typically satisfy this need either by linking - * against libGL.so on the command line (-lGL) or by dlopen'ing - * libGL.so.1.2 with the RTLD_GLOBAL flag. The JOGL implementation - * links against libGL on all platforms rather than forcing all OpenGL - * entry points to be called through a function pointer. This allows - * the JOGL library to link directly to core 1.1 OpenGL entry points - * like glVertex3f, while calling through function pointers for entry - * points from later OpenGL versions as well as from - * extensions. However, because libjogl.so (which links against - * libGL.so) is loaded by the JVM, and because the JVM implicitly uses - * RTLD_LOCAL in the implementation of System.loadLibrary(), this - * means via transitivity that the symbols for libGL.so have only - * RTLD_LOCAL visibility to the rest of the application, so the DRI - * drivers can not find the symbols required. <P> - * - * There are at least two possible solutions. One would be to change - * the JOGL implementation to call through function pointers uniformly - * so that it does not need to link against libGL.so. This is - * possible, but requires changes to GlueGen and also is not really - * necessary in any other situation than with the DRI drivers. Another - * solution is to force the first load of libGL.so.1.2 to be done - * dynamically with RTLD_GLOBAL before libjogl.so is loaded and causes - * libGL.so.1.2 to be loaded again.
