macOS bug with newest update

[brightly-salty]

After installing the new macOS update (I am currently on macOS Big Sur 11.1), which also updated the XCode Command Line Tools, I am unable to compile anything that depends on basically anything high-level. Originally posted here

I tried this code:

<default main code from `cargo new` with nom and async-std added as dependencies in Cargo.toml>

I expected to see this happen: Everything work normally, cargo downloads and installs it

Instead, this happened: Cargo failed to link with a nasty error about something missing in Command Line Tools.

error: build failed

Was able to fix with xcode-select --install. It had been installed prior to the update, so updating to 11.1 must have uninstalled the Command Line Tools.

Tried xcode-select --install xcode-select --reset didn't work for me.
Even tried deleting CommandLIne tools folder and reinstalling still no solution can't compile hello world.

This is still a problem.

Ok realized it's macOS big sur issue. The C libraries location have changed and thus rust can't find them.
The solution I ended up with was

export LIBRARY_PATH="/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib"

That's the current path for the libraries, until Apple changes again with a single update 😡

@dreson4 Are you on 11.0 or 11.1? After I updated to 11.1, there was a single text file in the Developer/CommandLineTools. After running xcode-select --install and following the prompts, I then ran cargo clean and cargo build again and everything worked again.

[dreson4]

I'm on 11.1.
I tried xcode-select --install, cargo clean , cargo build all didn't work, even deleting the command line tools folder, reinstalling x-code.
After exporting the LIBRARY_PATH the issue has been fixed. So it's ok for now.
