Not working with Big Sur?

[jean-philippe-martin]

I'm not sure whether this is a mistake on my side or a missing feature.

I have Big Sur (11.5.1) and when trying to run some cargo-instruments it fails saying "xctrace" is missing. Indeed, I can't find that binary.

% xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
% brew install cargo-instruments
Warning: cargo-instruments 0.4.1 is already installed and up-to-date.
% cargo instruments -t Allocations
Failed instruments errored: xcrun: error: unable to find utility "xctrace", not a developer tool or in PATH
% ls /Library/Developer/CommandLineTools/usr/bin/xtr*
zsh: no matches found

Is there something I can do to run cargo-instruments on this machine (it's an Intel machine, not M1).

hmm, I'm really not sure what's going on here. I assume you also can't run xcrun xctrace manually from the command line?

[jean-philippe-martin]

Indeed, it says it's not found:

% xcrun xctrace
xcrun: error: unable to find utility "xctrace", not a developer tool or in PATH

This link solved this problem for me.

Now I get the following error:

    Finished dev [unoptimized + debuginfo] target(s) in 0.06s
   Profiling target/debug/feophant-server with template 'Allocations'
      Failed instruments errored: [ERROR] Run issues detected (trace is still ready to be viewed):
* Failed to gain authorization

I'm looking at #40 to see if I can implement that solution.

Running into the same issue with xctrace not found:

❯ xcrun xctrace
xcrun: error: unable to find utility "xctrace", not a developer tool or in PATH

I'm on Catalina (10.15.7) and have the xcode command line tools installed. I also have instruments installed - could we add a command line argument for overriding the automatic detection with a user-provided value? Or maybe change the detection to check that we can run xcrun xctrace successfully before resolving to XcodeInstruments::Xctrace?

I'll try to get a PR up that works for me..

EDIT: Alright, I tried falling back to instruments and it required Xcode to be installed which is not the simple solution I was hoping for.

I'm running Big Sur 11.6 on an M1 Air. I have /usr/bin/instruments and also 'xcrun xctrace' works. But it still tells me Instruments is not installed:

$ cargo instruments -t Allocations

Xcode Instruments is not installed. Please install the Xcode Command Line Tools.

@GregoryTravis try xcode-select --install, does it tell you command line tools are installed already, or does it prompt you to install them? (If prompted install and this should work, if not I'm confused)

[GregoryTravis]

Yes, that did it. I already had the cli tools installed (I could run gcc/clang) but I guess this updated it. Is Instruments a recent addition?

[cmyr]

Nope, but sometimes the path to the tools can be unset, or need to be updated after a new Xcode release? I'm not really sure of all the failure conditions, I just know this happens sometimes 🤷

[trombonehero]

Maybe the CLI tools are now insufficient? I'm on Monterey (12.4), and attempting to run /usr/bin/xctrace yields:

xcode-select: error: tool 'xctrace' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

[cmyr]

hmm, perhaps? I haven't ever not had Xcode installed.
