SK-AM62A-LP: Compile C files using aarch64-oe-linux-gcc

I want to compile .C files using aarch64-oe-linux-gcc,but now there are many link errors when compiling.

If you want to use the compiler directly you'll need to specify the proper sysroot using the --sysroot parameter. However it's easier to just source the provided cross-compile ENV script which will take care of this for you, like this:

$ source environment-setup

> #include <stdio.h>

int main() {
    printf ("Hello World from TI!!!\n");
    return 0;
}
> EOF
[linux-devkit]:~/ti/ti-processor-sdk-linux-edgeai-am62axx-evm-09_01_00_07/linux-devkit> cat helloworld.c
#include <stdio.h>

int main() {
    printf ("Hello World from TI!!!\n");
    return 0;
}
[linux-devkit]:~/ti/ti-processor-sdk-linux-edgeai-am62axx-evm-09_01_00_07/linux-devkit> $CC helloworld.c -o helloworld
