[SOLVED] Cross Compiling with arm-none-eabi-gcc

Hi everybody, I started to write some script for my raspberry, but, because of performance gap, I decided to use C instead of python. The point is that i do not have a GUI installed and in any case it will be near impossible to use a IDE on a first generation raspberry. I wanted to use Eclipse on my laptop to compile for ARM.
I've installed arm-none-eabi-gcc pakage using pacman, but it doesn't compile even a simple Hello World.

arm-none-eabi-gcc test.c -o test 

generate these errors

I dust binned the other thread.  In the future, please use the report link on the thread and ask the moderators to move it for you.   Thanks.

I am not much on setting up cross compilers, and I am not a huge fan of large IDEs like eclipse.  I would consider using emacs with auto complete and gdb on the target.  Others here will suggest Vim.
The problems you are encountering are because  you using arm-none.  You should be using arm-linux (I think).   The none target does not know about Linux kernel calls .

I cross compile on Arch ARM (master) to my x86_64 box all the time.  See: https://wiki.archlinux.org/index.php/Distcc#Arch_ARM

Thanks a lot for the hints. Finally i installed arm-linux-gnueabihf-gcc, and now everything works fine.
