@JayeLovee I had the same sort of issue and was able to resolve it by installing MySQL development package. See #1266 .

[rawlingsr]

I was getting the same error. I was able to resolve it by installing a compatible connector for windows.

https://mariadb.com/downloads/connectors/

I did a typical install, and then installed the gem with the following command:

gem install mysql2 -- --with-mysql-dir="C:\Program Files\MariaDB\MariaDB Connector C 64-bit"

[dimahadgi]

I've tried a lot's different ways to install mysql2 gem on Windows Server 2019 and getting this error now: Ruby v 3 C:\Users\qauser>gem install mysql2 -- --with-mysql-dir="C:\Program Files\MariaDB\MariaDB Connector C 64-bit" ERROR: While executing gem ... (ArgumentError) undefined class/module YAML::Syck::

With ruby 2.7 I was able to install gem without this error.

[rawlingsr]

@dimahadgi I've tried on multiple machines, and I don't get that error.

I'm on ruby 3.1.2p20. gem -v gives 3.3.16. The connector version I downloaded was 3.1.17-GA. I'd try with those specific versions, as they seem to be the most up to date working combination. You can update rubygems using gem update --system

I had the same issue on Ubuntu 18.04.5, ruby 3.1.2, gem 3.3.7. Had to install libmysqlclient-dev.

For some reason, Ruby could not create the makefile for MySql since mkmf.rb#find_library was breaking on a nil value inside the paths array. I've monkey patched to compact this array, them I received the following message:

checking for -lmysqlclient... no

mysql client is missing. You may need to 'sudo apt-get install libmariadb-dev', 'sudo apt-get install libmysqlclient-dev' or 'sudo yum install mysql-devel', and try again.

After that I've installed libmysqlclient-dev and it worked on the next try.

I also encoutnered the same [i think] problem when building mysql2 from MSYS2 environment few days ago. I fixed it with following steps. Replace ucrt with x86_64 for your setup. 1) pacman -S mingw-w64-ucrt-x86_64-libmariadbclient 2) mkdir /tmp/mysql-lib-and-dll # we need to place dll+lib here; weirdly it seems that lib file is not used, but for some reason build fails without it. 3) touch /tmp/mysql-lib-and-dll/libmysql.lib # create blank file 4) cp /f/msys/ucrt64/bin/libmariadb.dll /tmp/mysql-lib-and-dll/libmysql.dll # mysql2 wants dll named libmysql 5) gem install mysql2 -- --with-mysql-lib="/tmp/mysql-lib-and-dll" --with-mysql-include="/f/msys/ucrt64/include/mariadb"

So I actually managed to build without mysql connector from mysql homepage, just using mingw build! I tried a few queries from rails and didnt notice any issues.
