How to install Valgrind on macOS Catalina (10.15) with Homebrew?

Question

I tried to install Valgrind with command brew install Valgrind and I get a message says:

\"valgrind: This formula either does not compile or function

Answer 1

See https://github.com/LouisBrunner/valgrind-macos/.

Either try

brew tap LouisBrunner/valgrind
brew install --HEAD LouisBrunner/valgrind/valgrind

Or compile it from the source, if the above method doesn't work. (But they should have fixed the above method just recently.)

git clone https://github.com/LouisBrunner/valgrind-macos.git
cd valgrind-macos
./autogen.sh
./configure --prefix=/where/you/want/it/installed --enable-only64bit
make 
sudo make install

Enjoy!

brew install --HEAD https://raw.githubusercontent.com/sowson/valgrind/master/valgrind.rb

MacOS Catalina (10.15.4), I was able to confirm the operation.
