Dear All,
I wish to check the the LD_DEBUG=reloc for both parent and child process.

Code of parent process p1, that is forking the child process p2
[ajeet_y@localhost ajeet]$ cat main1.c
#include <stdio.h>
#include <unistd.h>
int main()
{
         pid_t pid;
         printf("In P1\n");
         pid = fork();
         if (pid){
                 sleep(1);
         } else {
                 execve("./p2",NULL,NULL);

Here you completely replace the Environment of the process execing p2.

         }
}
[...]



Can anyone help me why I am not getting the relocation information of
process P2,

You are not getting the LD_DEBUG=reloc information because that environment variable is not set in P2 due to your elimination of the entire environment.

 and how to get it ?

Pass LD_DEBUG=reloc in the environment of any process for which you wish to see the dumps.
