Fix duplicated path in the "not found dylib" error by GuillaumeGomez · Pull Request #121978 · rust-lang/rust

GuillaumeGomez · 2024-03-04T13:34:49Z

While working on the gcc backend, I couldn't figure out why I had this error:

error: couldn't load codegen backend /checkout/compiler/rustc_codegen_gcc/target/release/librustc_codegen_gcc.so/checkout/compiler/rustc_codegen_gcc/target/release/librustc_codegen_gcc.so: cannot open shared object file: No such file or directory

As you can see, the path is duplicated for some reason. After investigating a bit more, I realized that libloading::Error::LoadLibraryExW starts with the path of the not found dylib, making it appear twice in our error afterward (because we do render it like this: {path}{err}, and since the err starts with the path...).

Thanks to @bjorn3 for linking me to #121392. :)
