GCC error - cannot execute binary file

[Thank you everyone!., sorry i didn't see the mismatched kernel, for some reason i was thinking this was my ubuntu server 64 bit]

I compiled a custom gcc tool chain using ct-ng, compilation was successful but i wrote a simple hello world and i see this error

Could someone, please point me what is wrong here and why i get this error?

Error:

src/main$ ./main 
bash: ./main: cannot execute binary file

And finally main2.c

#include <stdio.h>
int main() {
