Fail to compile rust library on linux

[abailly-iohk]

When I try to cargo build inside the rust directory, I get the following error:

error: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by /home/curry/mithril/rust/target/debug/deps/libzeroize_derive-f42e2238bc0119fb.so)
   --> /home/curry/.cargo/registry/src/github.com-1ecc6299db9ec823/zeroize-1.4.1/src/lib.rs:220:9
    |
220 | pub use zeroize_derive::Zeroize;
    |         ^^^^^^^^^^^^^^

error: could not compile `zeroize` due to previous error
warning: build failed, waiting for other jobs to finish...
error: build failed

I have tried googling and found issues related to static linking suggesting musl should be used instead but even removing the staticlib target does not fix it.

It works fine on local Mac OS, perhaps something related to nix env?

@iquerejeta @abakst Any suggestion on how to solve this?

[abailly-iohk]

rust code depends on a specific glibc version which was not present on the VM where I compiled it apparently. Bumping the VM's version to 21.10 fixed the issue, as well as explicitly installing a glibc 2.32 on earlier Ubuntu versions. Perhaps there's a way to ensure the right version is installed trough shell.nix?
We should run CI as a matrix build across various OSes to catch those issues.
