Why do I need a Cross Compiler?: Difference between revisions

You get a lot of useful programs when you build your cross-binutils. For instance, you get i686-elf-readelf, i686-elf-as, i686-elf-objdump, i686-elf-objcopy, and more. These programs know about your operating system and handle everything correctly. You can use some of the programs that come with your local operating system instead (readelf, objcopy, objdump) if they know about the file format of your operating system, but it is in general best to use your cross tools instead. These tools all consistently have the prefix 'i686-elf-' if the platform of your OS is i686-elf.
