Im trying to install an open source rails 3.2.21 application that uses the mysql2
gem, but when i try and run the bundle
commant I get the following error:
Fetching: mysql2-0.3.18.gem (100%)
Building native extensions. This could take a while...

I tried uninstalling every version of mysql
I installed via homebrew and reinstalling them, like so:
brew uninstall --force mysql && brew install mysql
Then running:
sudo gem install mysql2
As suggested by a number of similar questions asked on here, but it still results in the same error as above.
Please could someone offer guidance on how to get this up and running?
For anybody still experiencing the issue:
When you install openssl via brew, you should get the following message:
Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries
Generally there are no consequences of this for you. If you build your own software and it requires this formula, you'll need to add to your build variables:
LDFLAGS: -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include
PKG_CONFIG_PATH: /usr/local/opt/openssl/lib/pkgconfig
You can set these build flags (for the local application) by running the following:
bundle config --local build.mysql2 "--with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include"
This worked for me.
See bundler's documentation for more information.
The error log says:
ld: library not found for -lssl
So, you need to install libssl
:
brew install openssl
As it was pointed out in comments, there might be a need to export the path to the library.
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/
Try this:
gem install mysql2 -v '0.5.2' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
(Update version as appropriate)
The solution for me was to install the Xcode Command Line Tools.
I had recently updated Xcode through the Mac App Store, and every time I do that, I've found that I have to reinstall the Command Line Tools again.
xcode-select --install
Based on the solution here
brew install openssl
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/
solved the problem.
Thanks @mudasobwa for pointing me in the right direction. It turns out the error was caused by an unlinked openssl file, so running:
brew reinstall openssl && brew link openssl --force
Solved the problem. I found the solution here: OpenSSL, RVM, Brew, conflicting error
After Homebrew update (openssl@1.1) there is a new path for libs, so may use:
bundle config build.mysql2 --with-opt-dir=$(brew --prefix openssl)
bundle install
It will fix ld: library not found for -lssl error
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
The combination of commands solved it me. I am on Mojave.
brew reinstall openssl && brew link openssl --force
and then
gem install mysql2 -v '0.4.10' -- \
--with-ldflags=-L/usr/local/opt/openssl/lib \
--with-cppflags=-I/usr/local/opt/openssl/include
Seems that you miss the main files needed to build mysql2
gem
sudo apt-get install libsqlite3-dev libmysqlclient-dev -y
libsqlite3-dev
is not mandatory but install it since it's the default rails DB.
Mac Catalina 使用 Homebrew 修复: gem install mysql2 -- --with-opt-dir="$(brew --prefix openssl)"
the following command works for my Mac os 12.1 MacOs Monterey
gem install mysql2 -v '0.5.3' -- \
--with-mysql-lib=/opt/homebrew/Cellar/mysql/8.0.28/lib \
--with-mysql-dir=/opt/homebrew/Cellar/mysql/8.0.28 \
--with-mysql-config=/opt/homebrew/Cellar/mysql/8.0.28/bin/mysql_config \
--with-mysql-include=/opt/homebrew/Cellar/mysql/8.0.28/include
Please refer this link for more details https://github.com/brianmario/mysql2/issues/1175
This finally worked for me on macOS Monterey 12.3 (M1 Pro):
gem install mysql2 -- --with-mysql-dir=/opt/homebrew/Cellar/mysql/8.0.28_1
Make sure you read the installation instructions . Notable points for me were:
brew install mysql
)xcode-select --install
)with-mysql-dir
option to wherever mysql was installed (check with brew info mysql
)On MacBook air M1(macOS) it worked for me.
Install zstd
brew install zstd
Install mysql2
gem install mysql2 -v '0.5.3' -- --with-opt-dir=$(brew --prefix openssl) --with-ldflags=-L/opt/homebrew/Cellar/zstd/1.5.0/lib
Steps for me on Monterey M1 Mac
brew install openssl@3
brew install zstd
gem install mysql2 -v '0.5.3' -- --with-opt-dir=$(brew --prefix openssl) --with-ldflags=-L/opt/homebrew/Cellar/zstd/1.5.0/lib
bundle config --local build.mysql2 "--with-opt-dir=$(brew --prefix openssl) --with-ldflags=-L/opt/homebrew/Cellar/zstd/1.5.0/lib"
bundle install
Combining the answers given by Aleksei Matiushkin and Alexey Mozorov fixed the problem for me.
But I also updated the openssl before adding the path.
Thanks!
I've been coding with mysql2 gem for years and have encountered with this issue time to time.
Today I found that this magic option -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
no longer worked on my Mac. Indeed, it looks like the default location where brew installs openssl has changed:
$ brew reinstall openssl
...
If you need to have openssl@3 first in your PATH, run:
echo 'export PATH="/opt/homebrew/opt/openssl@3/bin:$PATH"' >> ~/.zshrc
For compilers to find openssl@3 you may need to set:
export LDFLAGS="-L/opt/homebrew/opt/openssl@3/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include"
So following the message, I had to make a few changes to the command and got it work finally:
$ gem install mysql2 -v '0.5.3' -- --with-ldflags=-L/opt/homebrew/opt/openssl@3/lib --with-cppflags=-I/opt/homebrew/opt/openssl@3/include
Hope this will help someone!
This helped me on MacOs 12.6 (Monterey)
brew install mysql openssl
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
gem install mysql2 -v '0.5.3' \
--source 'https://rubygems.org/' -- \
--with-cppflags=-I/usr/local/opt/openssl/include \
--with-ldflags=-L/usr/local/opt/openssl/lib
bundle install
Thanks https://github.com/brianmario/mysql2/issues/1175#issuecomment-1069721834
I found that I had to use --with-opt-dir=/usr/local/opt
.
Specifically, I added the following to my ~/.bundle/config
file:
BUNDLE_BUILD__MYSQL2: "--with-opt-dir=/usr/local/opt"
