I am following this tutorial to cross compile a simple C program:
/* myinit.c
* Build instructions:
* ${CROSS_COMPILE}gcc -static init.c -o init
* */
#include <stdio.h>
int
main ()
{
printf ("n");
printf ("Hello world from %s!n", __FILE__);
while (1) { }
return 0;
}
Now I save this is a .c file and try to compile it;
[root@xilinx Xilinx-ZC702-14.7]# arm-linux-gnu-gcc myinit.c myinit.c:6:19: fatal error: stdio.h: No such file or directory compilation terminated.
This is hapening only when I am using arm-linux-gnu-gcc.
But when I am using gcc, it works fine.
Why is arm-linux* giving this error?

Answer
The problem here, it seems, is that you installed the compiler toolchain for the target, but didn’t install a standard library for the target. You need a standard C library compiled specifically for your target platform. Either find a pre-compiled from the same place you found the compiler toolchain, or download one and cross-compile using the target toolchain.
When you have a standard C library for the target, use the flag -I (that’s uppercase i) to tell the compiler where to find the header files, and the -L flag to tell the linker where to find the libraries, and e.g. -lc (that’s the lower-case L) to tell the linker to link with the library. Something like
$ arm-linux-gnu-gcc -I/usr/local/target/include myinit.c -L/usr/local/target/lib -lc
