I create a head file in wireshark,name peformance.h:
#include <glib.h>
typedef struct peformance_s
{
gfloat time[100];
gfloat delay[100];
guint32 packetSize[100];
guint32 payload;
guint32 index;
guint32 temp_size;
gfloat temp_time;
}peformance;
extern peformance* peformance_test;
then I add the file to /gtk/main.c file ,
#include "peformance.h" //somebody told me not to use "../peformance.h" because there is subdir to search
peformance pef_test;
peformance *peformance_test=&pef_test;
in the ./wiretap/libpcap.c file, I want to use struct peformance ,
#include "peformance.h" //or #include "../peformance.h",i do not know which one to use
peformance_test->index=0;
it shows to me one error,the error information is :
" wiretap/.libs/libwiretap.so: undefined reference to `peformance_test' "
what is going on and why is that?
