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

Question

I tried to install Valgrind with the command "brew install valgrind" and I get a message that says:

"valgrind: This formula either does not compile or function as expected on macOS versions newer than Sierra due to an upstream incompatibility. Error: An unsatisfied requirement failed this build."

I also tried to "brew edit valgrind" and replace "sourceware.org/git/valgrind.git" with "git://sourceware.org/git/valgrind.git" in head section of the code, then wrote on Iterm "brew install --HEAD valgrind" but it gives me:

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!
