@chapter Development Tools

When porting RTEMS to a new CPU architecture, one will have to have a

development environment including compiler, assembler, linker, and

debugger.  The GNU development tool suite used by RTEMS supports most

modern CPU families.  Often all that is required is to add RTEMS

configurations for the target CPU family.  RTEMS targets for the GNU tools

usually start life as little more than aliases for existing embedded

configurations.  At this point in time, ELF is supported on most of the

CPU families with a tool target of the form CPU-elf.  If this target is

not supported by all of the GNU tools, then it will be necessary to

determine the configuration that makes the best starting point regardless

of the target object format.

Porting and retargetting the GNU tools is beyond the scope of this manual.

The best advice that can be offered is to look at the existing RTEMS

targets in the tool source and use that as a guideline.
