I'm using the following command in order to install lldb without Xcode

xcode-select --install

However, the window that pops up with the progress bar gets halted on task "Finding Software" Those are the relevant errors I could trace from log stream:

Code Block runningboardd: (RunningBoard) [com.apple.runningboard:process]
[daemon<com.apple.dt.CommandLineTools.installondemand(502)>:843] 
Error 45 setting darwin role to UserInteractive: Operation not supported, 
falling back to setting priority
runningboardd: (RunningBoard) [com.apple.runningboard:process] 
[daemon<com.apple.dt.CommandLineTools.installondemand(502)>:843] 
Error 45 setting darwin role to UserInteractiveFocal: Operation not supported, 
falling back to setting priority

Any idea how to tackle this issue?

  • lldb.llvm.org/#get-involved Why not build it from source ? Or download the binary releases.llvm.org/download.html#10.0.0 If not, you can also download CLT from developer.apple.com.

  • FWIW, I had the same issue in Big Sur beta 3 (when using Xcode 12 beta 3), and could not get around it. But, I no longer have the issue in beta4. I installed Xcode 12 beta 4, and this seems to have fixed this "bug".

This is fixed on macOS 11.1 BuildVersion 20C69 (and likely before now just I haven’t tried sooner to reproduce your issue).

You need to run the following:

xcode-select --install
sudo xcode-xelect -license

Press space to get to the end of the license and type agree.

Then open Applications folder and drag the calculator app icon into your command line window after typing lldb:

mike@m1 ~ % lldb /System/Applications/Calculator.app 
objc[17521]: Class AMSupportURLConnectionDelegate is implemented in both ?? (0x206a678f0) and ?? (0x1163582b8). One of the two will be used. Which one is undefined.
objc[17521]: Class AMSupportURLSession is implemented in both ?? (0x206a67940) and ?? (0x116358308). One of the two will be used. Which one is undefined.
(lldb) target create "/System/Applications/Calculator.app"
Current executable set to '/System/Applications/Calculator.app' (arm64e).
(lldb) exit
