I have an embedded system on a portable ARM device, and it runs a customized Linux. How can I build a native compiler for that Linux distro?
For example, I am now using machine A, and on A, I have both native compiler, and a cross-compiler for machine B. How can I build a compiler that can run directly on B?
I searched a bit, but only to find some tutorials of how to build cross compiler for B, but did not find how to build a native compiler through a cross compiler.
I'm not sure the marked answer is correct. I'm working on a project that mirrors the one in the original question and according to the link that n.m. posted, the original asker is attempting is called one of three things: a host-x-host, crossed native, or cross-built native...NOT a Canadian-Cross.
Unfortunately there does not seem to be any tutorials on this subject...at least none that I could find.
As I understand your question, you have fast non-ARM host and slow ARM. You want to build a compiler on your fast host; and compiler will be used on ARM system to compile code to ARM machine.
This setup is almost classic Canadian Cross:
Given three machines A, B, and C, one uses machine A (e.g. running Windows XP on an IA-32 processor) to build a cross compiler that runs on machine B (e.g. running Mac OS X on an x86-64 processor) to create executables for machine C (e.g. running Android on an ARM processor).
You have B=C and can use Canadian Cross build systems.
Unfortunately, this type of cross compilers are the hardest one. There are some manual to build such Cross: http://airs.com/ian/configure/configure_6.html ... or try to google "canadian cross gcc".
There are also some scripts to build embedded systems based on Linux. Will try to search some and add them here:
