It fails with the following output:

me too,how to fix?

This Pi arach64 Image just contain a runtime gcc/g++ complier. The same error occurs when jusy run gcc main.c -o main to printf “hello world.”

Just cross complie source code on other platform and excute the binary file on PI system.

Or if u have any other better solution, tell me pls.

@wanggao1990 @xiadeye U're not right, 1'st pls understand sid-used command from our readme. The system had not include libc-dev pkg by default, run command :

sid-used apt install libc6-dev-arm64-cross

root@raspbian:~# dpkg  -L libc6-dev-arm64-cross| grep -E "crtn|crti|Scrt1"
/usr/aarch64-linux-gnu/lib/Scrt1.o
/usr/aarch64-linux-gnu/lib/crti.o
/usr/aarch64-linux-gnu/lib/crtn.o

root@raspbian:~# cat test.c
#include <stdio.h>
int main(void)
{
  printf("Hello world!\n");
  return 0;
}
root@raspbian:~# gcc test.c
root@raspbian:~# ./a.out
Hello world!

The everything will be OK.

So, read readme file 1'st pls!!
