If the variable named version in packet-gtpcdr.c is a plugin version number, get rid of it - that's already taken care of in plugin.c.

If the variable named version in packet-gtpcdr.c is not a plugin version number, but is a variable used in the process of dissecting packets, either rename it or make it a local variable rather than a global variable (global variables are discouraged in dissectors).

Below is the code for variable named version. What do you suggest to modify?

#ifndef ENABLE_STATIC
G_MODULE_EXPORT const guint8 version[] = VERSION;
#endif

#ifndef ENABLE_STATIC
G_MODULE_EXPORT void
plugin_reg_handoff(void){
proto_reg_handoff_gtpcdr();
}
G_MODULE_EXPORT void
plugin_register (void) {
if (proto_gtpcdr == -1)
proto_register_gtpcdr();
}
#endif

If that code is in packet-gtpcdr.c, I suggest you remove all of it. That code should be in plugin.c, and probably already is in plugin.c.
