Installing mysql2 gem errors on MacOS Mojave.
Make sure openssl is installed on Mac via Homebrew.
brew install openssl
Install mysql2 gem.
gem install mysql2 -v '0.5.2' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
Great it works 👍
👍
this true solution is brew install mysql

On Apple silicon M1:
gem install mysql2 -v '0.5.3' -- --with-opt-dir=$(brew --prefix openssl)
The above did not work for me on Apple Silicon M1.
However, this worked:
gem install mysql2 -- --srcdir=/usr/local/mysql/include
Or with bundler
bundle config build.mysql2 --srcdir=/usr/local/mysql/include
bundle install
@shireeshj you are not using Homebrew?
@shireeshj you are not using Homebrew?
Using homebrew to install mysql.
bundle config build.mysql2 --srcdir=/usr/local/mysql/include
bundle install
This worked for me. Thanks all.
Alternative way is to install using Brew's Cellar Openssl. Tested on MacOS Big Sur with brew:
gem install mysql2 -v '0.4.10' -- --with-cflags=\"-I$(brew --cellar [email protected])/1.1.1k/include\" --with-ldflags=\"-L$(brew --cellar [email protected])/1.1.1k/lib\"
If you came here because you're trying to bundle your project into a specific directory and the gem won't build, you can tell bundler to use these build flags when it installs the gem.
bundle config build.mysql2 --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include bundle install --path .bundle
Thanks

I had the same issue on Mac Big Sur 11.6. after running these commands it worked:
brew install openssl
brew install mysql
then
gem install mysql2 -v '0.5.3' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include

Thanks @gukandrew 🥳
Thanks worked like a charm @gukandrew
bundle config build.mysql2 --srcdir=/usr/local/mysql/include
bundle install
This worked for me on MacOS Monterey w/ Macbook Air M1 2020
@gukandrew confirmed working for me on my MBA M1 2020
In case none of the solutions above worked for you on an Apple M1 silicon, you may want to have a look at this one:

This:
bundle config build.mysql2 --srcdir=/usr/local/mysql/include
bundle install
worked for me on Monterey 12.2.1 with M1 chip
Thank you @bparanj. That worked perfectly for me as well.
Tried all of the solutions from multiple sources/websites and the only one that worked on a M2 2023 was gem install mysql2 -v '0.3.18' -- --srcdir=/opt/homebrew/Cellar/mysql/8.0.33_2/include. Other solutions were working for more recent versions of the mysql2 gem though.

Awesome!!! This was the only solution that worked for me. You saved my day!
This is the key line in the error:
Note the extra backslashes; it's escaping the string in the bundle config so it's passed to
extconf.rbas a single parameter, which is silently ignored.In my case it was also enough to only specify the lib dir. I'm guessing the
--with-opt-dirin the newer comments is a way to set both with a single option in cases where the include dir also needs to be set. It would be better if bundle had a way to specify multiple parameters.I did this with
bundle config --local build.mysql2 --with-ldflags=-L/usr/local/opt/openssl/lib, including--localso it would be saved in the repo so future developers don't have to hunt this down like I did, but we'll see if that breaks our CICD.
