Exactly, it's a chicken and egg problem. C++ has tons of libraries, while Rust has barely any. Rust can use external C bindings, but not C++ ones yet. I think if they solve the issue of using C++ libraries from within Rust, the transition will be much easier, and meanwhile more native Rust libraries will be created.

Is the C++ ABI issue ever going to be solved?

[pjmlp]

Yes, in the cases where the operating system is done in C++.

The C ABI is the operating system ABI and it is only ubiquitous in operating systems done in C. Other operating systems use whatever ABI the system offers.

That's part of the problem they are facing. C is much easier to deal with.
