Can't run my hello world in C

I'm trying to write a basic program in C using gedit or sublime text (which I prefer), but no matter what I do when I try to compile or run, or even while writing, I have no option to use 'stdio.h' or any similar package. Even when I start typing #include <st the only word completion sublime suggests is 'struct'.

I've read dozens of threads, but all managed to fix this by installing gcc, which I've tried to reinstall multiple times, with no luck.

This is the output from gcc -v:

This is the code:

#include <stdio.h>

int main(void)
{
printf("hello, world\n");
}

When I compile using gcc, I get nothing, no error at least. but when I try to run using just ./hello.c this is what I get.

Solution 1:

gcc creates an executable file called a.out by default. Run that instead.

Alternatively, create a sensible named executable:

gcc -o hello hello.c

And even simpler, using the default rules built into make:

make hello

Solution 2:

You need to install the corresponding package with the headers (normally libc6-dev) with

sudo apt-get install libc6-dev

And for sure install build-essential with

sudo apt-get install build-essential

Then compile your hello.c with the command:

gcc hello.c -o hello

and run it:

./hello
