Is there a way to install Valgrind on Catalina and have it run properly? If so, I would very much appreciate a step-by-step process.
I tried installing Valgrind with https://github.com/sowson/valgrind
but when I tested out helloWorld.cpp
on the terminal, the console returned errors I should not have gotten.
I'm not sure if I committed an error on my part in the installation process of this version of Valgrind or if Valgrind itself is simply incompatible with Catalina OS.
I have also tried installing Valgrind via Homebrew, but I've had issues with that as well (github.com/Homebrew/homebrew-core/issues/36683).
Currently, no. The repo you link has an issue raised about Catalina compatibility. As you also show, the brew package has its own problems as well. Official valgrind only supports 10.12.
You'll just have to wait, or containerize it. Although if you containerize valgrind, you would likely need a compatible build container as well.
