This tool works on windows wsl2 and macOS 12.

It is not really an issue but I want to share if people are wondering whether this tool works on other platforms other than real linux.

I test it under OCaml 4.14.0.

wsl2 (work)

For ubuntu 20.04 on windows wsl2, just follow the instructions in Readme.md.

mac + lldb (work)

For macOS 12, I build lldb-mi from the source. I follow the instructions in section Building against custom LLDB with llvm installed from homebrew:

cmake . -DLLVM_DIR=/usr/local/opt/llvm/lib/cmake/llvm
cmake --build .

Then I change the command a bit:

gdbprofiler -p `pgrep my_example_program.native` --cpuprofile example.cpuprofile --callgrind callgrind.out --use-lldb

mac + gdb (not work)

I don't figure out how to use gdb mode on mac.

I installed gdb from homebrew and followed the certificate signing suggested in the brew installation log. After doing the manual steps, I can enter the normal gdb. However, when running gdbprofiler, my program always exits immediately. I guess there may be some interrupt.

(since mac+llvm works, I don't delve into it)

Thanks for letting me know!

I mostly prefer perf over gdbprofiler these days (see this thread), since it has much less overhead. perf should also work on wsl2, but not on Macs.

I see! I am attempting several OCaml profiling tools recently. perf looks good to me. Thanks for sharing the link.
