Verification

• My brew doctor output says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

I installed llvm@17 because vscode lldb plugin doesn't work with lldb 18.

What happened (include all command output)?

llvm@17 installation misses lldb binary and libraries.

What did you expect to happen?

llvm@17 should contain lldb.

Step-by-step reproduction instructions (by running brew commands)

brew install llvm@17
ls /opt/homebrew/Cellar/llvm@17/17.0.6/lib/

lldb-vscode was renamed to lldb-dap in LLVM.

The VSCode LLDB plugin should work with LLVM 18 if you configure it to use lldb-dap instead of lldb-vscode.

If that doesn't work, please report this issue to the VSCode LLDB plugin maintainers first.

[mizvekov]

The fact lldb-18 didn't work with vscode is a bit of a background information / motivation on my part.

It's still strange this part of the formula is not built when versioned, when it did build for previous versions.

As an llvm developer and compiler engineer, it sure is interesting to be able to test and try lldb-17, just as much as we can with clang-17 and other llvm tools, in order to properly identify regressions and such.

[carlocab]

Might've been better to lead with that.

We didn't build LLDB for llvm@17 to reduce the burden on our (limited, self-hosted) build infrastructure. And most users don't have as much need for older versions of LLDB.

But I'm happy to review a PR that returns LLDB to llvm@17's LLVM_ENABLE_PROJECTS configuration.
