crosstool-ng -- stdio.h: No such file or directory

I would like to cross compile a simple program that uses libncurses on my x86_64. Target system is MIPS.

My crosstool-ng-1.20 build went fine (with sample mips-unknown-elf)

However, a simple hello world ends badly.

#include <stdio.h>       

int main(void)           
{                        
    printf("OH HAI.\n"); 
    return 0;            
}

--

x86host:~/toolchain$ mips-unknown-elf-gcc -o hello hello.c

hello.c:1:19: fatal error: stdio.h: No such file or directory
 #include <stdio.h>
                   ^
compilation terminated.

I'm clearly doing something terribly wrong here, but where do i start?

[Edit]

Thank you markgz. Codesourcery is exactly what i needed.

mips-linux-gnu-gcc.exe -static -o helloStatic hello.c

Proof of concept complete. Now off to compile my ncurses program.

root@x86host:~/ncurses-5.9-20141101# export CC=mips-linux-gnu-gcc
root@x86host:~/ncurses-5.9-20141101# ./configure --target=mips-linux-gnu --host=mips-linux-gnu
[..]
root@x86host:~/ncurses-5.9-20141101# make

Then, i copied over a few headers from /usr/include/ to make these go away:

root@x86host:~/ninvaders-0.1.1# make
In file included from ./ncurses.h:1685:0,
             from view.h:25,

 #include <curses.h>
                ^
compilation terminated.
make: *** [view.o] Error 1


root@x86host:~/ninvaders-0.1.1# make

root@x86host:~/ninvaders-0.1.1# ls -l nInvaders
-rwxr-xr-x 1 root root 933003 Nov  6 16:18 nInvaders
root@x86host:~/ninvaders-0.1.1# mv nInvaders nInvaders_IOSXE_MIPS

For future googlers, Makefile is:

CC=mips-linux-gnu-gcc -static
CFLAGS=-O -Wall
LIBS=-lncurses
LDFLAGS=-L /root/ncurses-5.9-20141101/lib

CFILES=globals.c view.c aliens.c ufo.c player.c nInvaders.c
HFILES=globals.h view.h aliens.h ufo.h player.h nInvaders.h
OFILES=globals.o view.o aliens.o ufo.o player.o nInvaders.o
all:            nInvaders

nInvaders:      $(OFILES) $(HFILES)
                $(CC) $(LDFLAGS) -o$@ $(OFILES) $(LIBS)

.c.o:
                $(CC) -c  -I. $(CFLAGS) $(OPTIONS) $<
clean:
                rm -f nInvaders $(OFILES)

End result:

root@x86host:~/ninvaders-0.1.1# file nInvaders_IOSXE_MIPS
nInvaders_IOSXE_MIPS: ELF 32-bit MSB  executable, MIPS, 
MIPS32 rel2 version 1, statically linked, for GNU/Linux 2.6.16, not stripped

You probably needed to build mips-linux-elf-gcc. Are you sure your MIPS target system is configured as big-endian?

Anyway, you can avoid all these problems by downloading the free Mentor/Codesourcery MIPS gnu/gcc cross compilation tool chain from here. This toolchain is available for both Windows and Linux.
