issues when compiling c program using gcc and pthread library[SOLVED]
so i have these lines of code:
#include <bits/pthreadtypes.h>
#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
void* thread_funch(pthread_mutex_t* interlock,int* thread) {
pthread_mutex_lock(interlock);
printf("testing thread %d",*thread);
pthread_mutex_unlock(interlock);
pthread_exit(NULL);
}
int main () {
printf("test");
pthread_mutex_t interlock=PTHREAD_MUTEX_INITIALIZER;
//thread initializer would go here
return 0;
} whenever i attempt to compile it using GNU gcc on terminal i get these errors:

| it appears that some c libraries at /usr/include/ are either corrupt or missing , and if so where i can download them?, the errors are caused in the header.h files and not on the code itself,
searching for solution into the web didn't helped ether, I also attempted to possibly reinstall sources of the usr/include by reinstalling the packeges linux-headers , linux-api-headers, glibc, lib32-glibc and restarting the system without success

Re: issues when compiling c program using gcc and pthread library[SOLVED]
Generally speaking, if you want help with such problems, you should show the compiler command used. But in this case, the problem is simple: remove the first include line (with the "bits" header). Why was that even there in the first place?
Also, while not likely relevant to this concern, if you want that XOPEN_SOURCE macro to do anything, it needs to be defined before the includes. Though I'm not sure why it's there as you are not using any SUSv3-specific features (or even headers that have any SUSv3 feature tests).

even if the #define XOPEN_SOURCE is placed in the first line or removed nothing has changed
gcc -std=c11 test.c
gcc -std=c11 test2.c doesn't still doesn't change it , it still puts other errors and continues to display the same errors

Seriously, you ignore the part where he tells you what the problem is and focus on the part that says "while not likely relevant to this concern"

Seriously? That's what you took from my post? You confirmed that the one thing I said was not relevant to the currently problem was not relevant while also confirming that what I said was useless was useless... all the while completely ignoring the actual solution that was provided.
(edit: cross posted ... creating an echo)

you were right the first include was wrong
