Which C++ compiler is the best to create new operating system ?
Most important for maximum portability is that you use C++ standard features only. No compiler specific extensions or libraries. And even so stick to "plain" C++. No exotic features. And I would leave C++ 11 features alone since it will be years until most compilers are standard compliant.Quote:

if you create your own OS
You will at the very least need to create your own runtime library to have the C++ library interface to the OS.
If your OS has it's own executable format, you will probably need to create your own compiler, or at the least your own linker to produce executables in the formay your OS supports.
if you are building on top of an existing OS, then you're easiest to use a compiler already supported on that OS.
For which processor family?Quote:

Could you more precisily describe the steps, which are needed, in detail?
You need to become familiar with cross-compiling and bootstrapping.Quote:

I suggest you have a look at a small simple and cheap computer called Raspberry PI:
http://www.makeuseof.com/tag/7-opera...-raspberry-pi/
This may not be your immediate target machine but it's better to start small and use a hardware that's developed for educational purposes. And you get in touch with a user community sharing your interests where you can ask concrete questions. You may even be able to convince other people to try out your OS and give feedback and become costumers eventually.
If you can get a rudimentary OS up and running on the Raspberry PI you've taken a big leap on the road to becoming the new Bill Gates or Steven Jobs :). I would make Raspberry PI my first step.
Thank you.Quote:

I made my own bootstrap and C++library for an intel galileo (intel's "arduino clone"), and use a generic C++ compiler that outputs a form of bytecode binaries, then I covert the bytecode to galileo instructions.
Hardest part in the lib was making the cin read from and cout write to the USB port and have the generic named streams behave as the input and output pins.
Yes, there's a reason I didn't use the normal arduino dev kit for this (don't ask).
