Arm-elf

Question

Hi,
Ive downloaded the cross-arm-elf packages from community. And I got a few problems with it:
First I needed the stdio.h file, which seems not to be included in the package...?
further, the arm-elf-ld is not configured to use sysroot..
I get these two error-messages when I follow the "gnuarm.org -> support" example -- which I thought would work. I find this pretty uphill to make this work, but I will dick deeper into it.
I've made et work partly by adding another include-directory
$ arm-elf-gcc -mcpu=arm7tdmi -mthumb -O2 -g -c hello.c
hello.c:1:19: error: stdio.h: No such file or directory
$ arm-elf-gcc -mcpu=arm7tdmi -mthumb -O2 -g -I /usr/local/arm/arm-elf/include/ -c hello.c
$ arm-elf-gcc -mcpu=arm7tdmi -mthumb -o hello hello.o -lc/usr/bin/arm-elf-ld: this linker was not configured to use sysroots
collect2: ld returned 1 exit status
Anyway, please post fixes and let me know if I'm the only one who has this problem
the c-code is just a hello world one
#include <stdio.h>
int main(void)
printf "hello world \n"
return 0;

You are not alone to have this problem:
/usr/bin/arm-elf-ld: this linker was not configured to use sysroots
I got this when trying to compile a basic "blink" example program.
Does someone knows how to solve this ?
thx,
Olivier
