OS: CentOS 7 x86_64
I am working on a C (later ADA) cross-compiler from x86_64 to PowerPC32. CentOS 7 has a cross-compiler already built in its default repository, so through yum, I ran
yum install gcc-powerpc64-linux-gnu.x86_64
Although this is a ppc64 compiler, I can pass a flag to force 32-bit mode so for now, that does not worry me. I just want to get it compiling even in 64-bit mode.
I am trying to compile the following hello world program:
#include <stdio.h>
int main()
{
printf("Hello, World!");
return 0;
}
When I ran this with regular gcc, it compiles and runs just fine. The problem is that when compiling I get the error mentioned above.
Here is the output of the compilation command
[root@dev cross-compil-tests]# powerpc64-linux-gnu-gcc -o hello hello.c -v
Using built-in specs.

The ignoring nonexistent directory entries might be the problem. I do not know how to fix it, and have removed/reinstalled the cross-compiler multiple times. I also cannot find a C library for the cross-compiler that I can download so that I can link it manually with the -I flag.
Attempted Solutions
I did a:
find stdio.h | grep stdio.h
and linked the directory of where I found it using -I. New error, could not find stubs-32.h... Well ok, fixed that through some more googling (simple yum install) and then I got crt1.o not found... etc. Frustrating, but I believe this was not the correct direction to go anyways.
here is the ones my computer found
[root@lxdev-gab gnu]# find "stdio.h" / | grep "stdio.h"
find: ‘stdio.h’: No such file or directory
/usr/include/bits/stdio.h
/usr/include/stdio.h
/usr/include/c++/4.8.2/tr1/stdio.h
/usr/share/man/man0p/stdio.h.0p.gz
Any suggestions?
