I found an issue on ocaml repo ( which talks about this issue. The root cause was determined to be a change in glibc 2.34. The problem has been fixed there, but on more recent (and stock) versions of the ocaml compiler.

glibc on my system is indeed 2.34.

$  ldd --version
ldd (GNU libc) 2.34

I suspect more and more people will start encountering this error soon because rescript uses OCaml 4.06 (if my understanding is correct).

Full log here: Rescript installation error (probably due to glibc 2.34) -

Can you install OCaml on your system? Which version is default?

I can install OCaml via opam.

$ opam init
