Error installing mysql2 on Mac M1 pro (ventura)

[VictorOnwukwe]

Hello. I am trying to install mysql2 on my macOS M1 pro (ventura 13.3.1) using the below command:

gem install mysql2 -v '0.5.5' -- --with-mysql-config=$(brew --prefix mysql)/bin/mysql_config --with-ldflags="-L$(brew --prefix zstd)/lib -L$(brew --prefix openssl)/lib" --with-cppflags=-I$(brew --prefix openssl)/include

as suggested here

I am getting the below error

Building native extensions with: '--with-mysql-config=/opt/homebrew/opt/mysql/bin/mysql_config --with-ldflags=-L/opt/homebrew/opt/zstd/lib -L/opt/homebrew/opt/openssl@3/lib --with-cppflags=-I/opt/homebrew/opt/openssl@3/include'
This could take a while...

To see why this extension failed to compile, please check the mkmf.log which can be found here:

Any suggestion will be appreciated. I'll be happy to provide any further required information.

After trying just about every proposed solution by both humans and AI, I eventually resolved this issue by uninstalling ruby and rvm completely and then reinstalling. I still don't know what caused the issue. But this was my fix. Just leaving this out here.

@VictorOnwukwe Could you please share here which tutorial you followed to install all, even I have the same issue, struggling with it.

[VictorOnwukwe]

@sreenak I can't recall the tutorial I followed, but I stored the command that worked. Here it is:

gem install mysql2 -v ‘0.5.5’ -- --with-ldflags=-L/opt/homebrew/opt/openssl@3/lib --with-cppflags=-I/opt/homebrew/opt/openssl@3/include

Just in case the other commands don't work. This is what worked for me.

• MacOS Sonoma (14.2.1) - M1 Max w/ zsh & rbenv
• ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [arm64-darwin23]

gem uninstall mysql2

bundle config --local build.mysql2 -- --with-mysql-config=$(brew --prefix mysql)/bin/mysql_config --with-ldflags="-L$(brew --prefix zstd)/lib -L$(brew --prefix openssl)/lib" --with-cppflags=-I$(brew --prefix openssl)/include --with-cflags="-Wno-error=implicit-function-declaration"

bundle install
