cargo build gives: "cannot find function pthread_atfork in crate libc "

[shrsulav]

I am trying to use this for generating and analyzing ASTs for Rust programs.
However, on first cargo build, it's giving me this error.

I am running this in Ubuntu VM with Windows as host.
What steps should I perform to build this?

Bump version of lib in Cargo.toml.
Use this

[dependencies]
pad = "0.1.6"
libc="0.2.126"
syntex_syntax = "0.59.1"
