Can musl libc replace the libc of nuttx system？
I am currently working on a project that I want to transplant musl LIC to nuttx to replace the built-in libc, have any friends done similar work? I want to ask how to start.Thank you.
Re: QUESTIONS
Hi Briann, The main idea of NuttX RTOS is to have a POSIX and in some way a Linux-like RTOS that runs on low/mid-end microcontrollers, like STM32, ESP32, etc. You also can run NuttX on high-end processors like Freescale/NXP iMX6 and others. Then in theory you can port Java Virtual Machine and even run apps that uses it, but AFAIK nobody did it until now. Maybe because you can use Linux itself, or Free/Open/Net(BSD) to do it.

Hi Prelude, I don't think someone already tried it before. BTW, why do you want to do it?

Re: Can musl libc replace the libc of nuttx system？
musl is designed to work exclusively with Linux and then there is no OS abstraction layer. So it's hard to adapt musl to other OS. Alan asks a good question: what benefit do you want to get from replacing NuttX' libc with musl?

Re: Can musl libc replace the libc of nuttx system？
People have talked about using other C libraries in the past, but no one has been successful. C libraries support an operating specific interface. For example, a Linux LibC will need to use Linux system calls and Linux data structures to interface with the kernel. A similar interface would be needed to work with NuttX. MUSL supports only Linux. Hopefully, the MUSL OS interface is well modularized to support use of a different OS. Some things have very intense interactions such as C standard I/O and buffered I/O. A good contributor who is no longer associated with the NuttX project looked into using newlib with NuttX 10 or 12 years ago and said that the effort would be quite large. It is technically feasible and there is no known single show-stopping issue. But there would be many, many smaller issues of compatibility with header files, data structures, etc. This effort would be complex, invasive, and probably more work than anyone really would want to commit to doing. He said it would be like “a death from a thousand cuts.” If there is missing functionality in the NuttX LibC, most people would opt to extend the NuttX LibC, not port a different Libc. But if you are willing to put in a significant effort, then perhaps you could be successful. Since this would require the development of the OS interface as part of MUSL, it would not be a part of NuttX; it would be a part of MUSL. If you are serious about pursuing this, you really should be discussing the effort with Rich Felker and the MUSL team.
