os161: TLB miss for getpidtest

Question

Im trying to test my getpid.c from os161 and it gives this error, i know its because it is trying to access some invalid pointer but it does not make any sense. I tried gdb and i cant really use it because i dont know where the error is coming from much less why it is even getting this error. All i want to do is test my getpid function. :

OS/161 kernel [? for menu]: p testbin/getpidtest

in thread create

after thread allocated

DEBUG LOG[Thread.c create()] generating pid

DEBUG LOG[Thread.c generate_pid()] pid generated...

DEBUG LOG[Thread.c create()] got the pid, the pid is: 2

DEBUG LOG[Thread.c create()] thread create success

The only hint i see is that when i compile my system it doesnt really give any errors but whilst its compiling i briefly see this and im not sure why its doing that i havent done anything with a makefile except in my test but its just a template of my forktest where i just changed the name of forktest to getpidtest which is what i was told to do when making test :

MAKE[2] *** No rule to make target 'include'. Stop.

make[1] ** [Makefile:45: include] Error 2

make: *** [Makefile:23 all] Error 2

make includes

i made a getpid test that has all the includes theres an executable and everything. I have tried using GDB to pinpoint the problem, i cant find it. The purpose of me making the test was so i could test my sys_getpid function in my getpid.c

*/
int
main(int argc, char *argv[])
{



        mypid = getpid();

my sys_getpid function in getpid.c

int sys_getpid(int *retval){

        kprintf("DEBUG:GETTING PID:%d...\n", curthread->pid);
        *retval = curthread->pid;

        return 0;

}

how it is called in ssycall.c

 case SYS_getpid:
+                 kprintf("attempting to call getpid[syscall.c]\n");
+                 err = sys_getpid(&retval);
+                 break;
