jni_md.h has an empty definition of JNIEXPORT macro.
jni_md.h line 29:#define JNIEXPORT
Since GCC 4, GCC supports symbol visibility. If compiler option
-fvisibility=hidden, then all symbols are hidden by default and export
symbols should be marked with __attribute__ ((visibility
("default"))).
Thus, correct definition for JNIEXPORT would be:
#if __GNUC__ >= 4
#define JNIEXPORT __attribute__ ((visibility ("default")))
#else
#define JNIEXPORT
#endif
