## Fully static builds with musl libc
(By Frank Pagliughi)
[musl libc](https://musl.libc.org/) is is an implementation of the C standard library built on top of the Linux system call API, including interfaces defined in the base language standard, POSIX, and widely agreed-upon extensions.
Users of the Rust library, which wraps this one, had been complaining that they could not compile using the musl build tools. Musl is a small std C lib that can be statically linked. With the latest Paho C library (and a very minor tweak to the build), we're now able to build Rust apps using musl and Paho C that are fully static; no runtime dependencies on the platform; not even on the standard C lib.
$ ./async_publish

$ ldd async_publish
not a dynamic executable
So, for example, if maintaining a suite of apps for some newer and older embedded Linux boards, the same executables could be deployed without worry about the C ABI on the particular boards.
Certainly C apps using the Paho library could do this also.
