The OS is 10.14.6 (Mojave).
and the command returns this:
```julia
geo145:~ imac$ echo 'int main(void) { return 0; }' | clang -x c -o main.o -
geo145:~ imac$ /Applications/Julia-1.10.app/Contents/Resources/julia/libexec/julia/lld -flavor darwin -arch x86_64 -o main main.o
dyld: Library not loaded: @rpath/libLLVM.dylib

Right, sorry, we need to set `DYLD_FALLBACK_LIBRARY_PATH`, could you please try
```julia
echo 'int main(void) { return 0; }' | clang -x c -o main.o -
DYLD_FALLBACK_LIBRARY_PATH="/Applications/Julia-1.10.app/Contents/Resources/julia/lib/julia:/Applications/Julia-1.10.app/Contents/Resources/julia/lib" /Applications/Julia-1.10.app/Contents/Resources/julia/libexec/julia/lld -flavor darwin -arch x86_64 -platform_version macos 13.3.1 13.3 -o main main.o
```

It also produces “image not found”
```julia

geo145:~ imac$ DYLD_FALLBACK_LIBRARY_PATH="/Applications/Julia-1.10.app/Contents/Resources/julia/lib/julia:/Applications/Julia-1.10.app/Contents/Resources/julia/lib" /Applications/Julia-1.10.app/Contents/Resources/julia/libexec/julia/lld -flavor darwin -arch x86_64 -o main main.o

Uhm, do you have SIP enabled? Can you try to temporary disable it following the instructions at [Disabling and Enabling System Integrity Protection | Apple Developer Documentation](https://developer.apple.com/documentation/security/disabling_and_enabling_system_integrity_protection) and try again? Edit: but lld shouldn’t fall inside SIP cover, so I’m not sure it’s that one.

I had a similar problem. VSCode was unable to open the precompiled LanguageServer package. It was resolved by uninstalling the Julia extension in VSCode, the quitting VSCode, then starting it again and reinstalling the extension.
