'Error in thread 'main' panicked at 'Building libffi',

System: Ubuntu 22.04 LTS (Wayland). I am trying to build a simple rsmpi code (Rust+MPI), but I am unable to build it because of the error : thread 'main' panicked at 'Building libffi'.

My Carg.toml file is:

[package]
name = "heat_equation_mpi"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
#mpi = { git = "https://github.com/bsteinb/rsmpi", rev = "f9aec8b8d82" }
mpi = "0.5.4"

The error shown is:

error: failed to run custom build command for `libffi-sys v0.6.0`
Caused by:process didn't exit successfully:
..... some lines here ....
  thread 'main' panicked at 'Building libffi', /home/my_name/.cargo/registry/src/github.com-1ecc6299db9ec823/libffi-sys-0.6.0/build.rs:27:9

Can someone please help?

Libffi author here. Sven is right -- your system is missing makeinfo. On my fedora box, this is provided by the texinfo package.
