Hello,

I have a global variable in a .c file in the wireshark/epan/dissectors/ folder. How do I use it in another .c file in the wireshark/gtk/ folder? Every time I try using extern, I get an "undefined reference" error. I am able to use the same variable in another .c file in the epan/ folder. Is there anything I am missing?

 

The exact error I am getting is

 

/home1/vishnu.bhatt/11.2.1/wireshark_3g/gtk/call_trace.c:139: undefined reference to `UE_trace_IMSI_table'

 

“UE_trace_IMSI_table” is a global variable defined in /home1/vishnu.bhatt/11.2.1/wireshark_3g/epan/dissectors/packet-abc.c

 

And I am trying to use “UE_trace_IMSI_table” in /home1/vishnu.bhatt/11.2.1/wireshark_3g/gtk/call_trace.c

 

I have declared “UE_trace_IMSI_table” in /home1/vishnu.bhatt/11.2.1/wireshark_3g/gtk/call_trace.h

 

Any help will be appreciated.

 

Thanks and Regards

Vishnu Bhatt
