Issue

I tried to run mirai on one of my projects (a simple no-std library for parsing INI files) and got a very strange error.

Steps to Reproduce

$ git clone https://github.com/VorpalBlade/ini-roundtrip
$ cd ini-roundtrip
$ git checkout 9d2589f4d5a845a9a19249e5b3bfe6b49c893c85
$ cargo mirai
    Checking cfg-if v1.0.0
    Checking ini-roundtrip v0.1.3 (/home/arvid/src/chmm/ini-roundtrip)
/home/arvid/.cargo/bin/mirai: error while loading shared libraries: librustc_driver-0c79f0a768565e4a.so: cannot open shared object file: No such file or directory
error: could not compile `ini-roundtrip` (lib)

Expected Behavior

Not give a strange error aout a rustc driver .so file?

Actual Results

/home/arvid/.cargo/bin/mirai: error while loading shared libraries: librustc_driver-0c79f0a768565e4a.so: cannot open shared object file: No such file or directory

Environment

Rust version (rustc --version): rustc 1.79.0 (129f3b996 2024-06-10) Mirai commit: 6a91ee00efcd5eb0b8eab51fa51ab00f0f22eb13 OS: Arch Linux (rolling release) Rust is installed via rustup

Update: This seems to happen on any project I try. Even a simple hello world one.

It happened to me too.

LD_LIBRARY_PATH=$HOME/.rustup/toolchains/nightly-2023-12-07-x86_64-unknown-linux-gnu/lib/ cargo mirai works as a workaround for me. This suggests somehow the linking is screwed up, perhaps it should use rpath?

It seems that something has changed in cargo that breaks plugins like MIRAI. I'll try to look into it, but it is going to take a while before I can get to it.
