Trouble following the article on how to develop an OS with C++

Hello! So, I am following this article: http://www.cplusplus.com/articles/zv07M4Gy/

I find myself troubled in the "how to compile it" section. It says to run the following commands:

nasm -f elf boot.asm -o boot.o
g++ -c kernel.cpp -o kernel.o -ffreestandinng -fno-exceptions -fno-rtti
gcc loader.o kernel.o -T linker.ld -o kern -nostdlib -nodefaultlibs -lgcc

The first problem is that the "-ffreestandinng" parameter doesn't seem to exist. Also, the loader.o file is not explained where we actually get it from. I thought that maybe he meant the bootloader, but if that is the case how we get this ".o" file?

Thank you very much !

Looks like a spelling error.

"-ffreestanding"

You are right! It is a typo .. Now it works ... the only thing I need to find now is what is this "loader.o" fellow.
I expect it's just straight up missing. You might do better over here: http://wiki.osdev.org/Bare_Bones#Writing_a_kernel_in_C
Hahahaha the cross-compiler part itself its impossible to make it through without getting a cancer or two in the process. Thank you very much both for your hlep anyway !
