To access this special symbol:
[hjl@gnu-tgl-3 tmp]$ cat c.c
#include <stdio.h>
extern char GLOBAL_OFFSET_TABLE[];
char *ptr = GLOBAL_OFFSET_TABLE;
int main() {
printf("%lx\n", (unsigned long)ptr);
}
[hjl@gnu-tgl-3 tmp]$ gcc -m32 c.c
/usr/local/bin/ld: /tmp/ccK14eSl.o:(.data+0x0): undefined reference to
`GLOBAL_OFFSET_TABLE'
collect2: error: ld returned 1 exit status
[hjl@gnu-tgl-3 tmp]$ gcc -m32 c.c
-Wl,--defsym,GLOBAL_OFFSET_TABLE=_GLOBAL_OFFSET_TABLE_
[hjl@gnu-tgl-3 tmp]$ ./a.out
