I have a problem with an install of mysql gem. This is my error :

I don't understand what happened and how to solved this. If someone could help me...
The mysql gem is one of many gems which doesn't like the unification of the integer types in Ruby 2.4.
Unfortunately, since the mysql gem isn't really maintained anymore, I wouldn't hold my breath for an updated version. As a workaround, you can switch to a Ruby version before 2.4, e.g. Ruby 2.3.3.
Alternatively, you could switch to the mysql2 gem which is actively maintained, has a similar API to the mysql gem and in its latest version is compatible with Ruby 2.4.

Got stuck with this for quite some time, any help would be much appreciated.
From Terminal try following:
For Ubuntu:
sudo apt-get install mysql-client libmysqlclient-dev
sudo gem install mysql2
For Mac:
brew install mysql
sudo gem install mysql2
try the below:
gem install rails
After that install mysql server
sudo apt-get install mysql-client libmysqlclient-dev
then bundle install
When trying to run a rails server in my current directory (which is a new rails project), it says that I need to install the mysql2 gem. At first, I had no idea what this meant... Then, I did some poking around, and finally decided to install the gem. However, I am getting this super pesky error (seeing as I just spent 2 hours trying to investigate, and solve another error). I am on the brink of giving up, but I really want to try rails. Please help!
Currently, if I run sudo gem install mysql2, or even as some people told me to do online, gem install mysql -- \ --with-mysql-config=/Applications/MAMP/Library/bin/mysql_config (I have MAMP), it gives me the following error:

Have you considered installing MySQL with homebrew (http://brew.sh/)? MAMP stands for Mac-Apache-MySQL-PHP (the last part of this being the most important). I would suggest just installing MySQL directly on your box (homebrew takes care of all the heavy lifting) and afterwards I doubt you'll have any difficulty installing that gem.
To install homebrew --
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
Run brew doctor follow any instructions and then afterwards to install MySQL run brew install mysql and follow any of the instructions it provides for setting up a user, etc...
============= UPDATE ==============
SO, what you'll want to do is use brew this way to install MySQL and then install the gem in the normal fashion - sudo gem install mysql2 assuming this works, then you will be able to switch back to the old MySQL install through MAMP via -
sudo nano /etc/paths
then add this line to the top of the document -
/Applications/MAMP/Library/bin
restart your terminal and then run mysql to double check that you are using the MAMP installation of MySQL, and you'll be good to go.
Here is my stack:
RHEL 5.8 x86_64

I am installing mysql2 0.3.11 gem through bundler and got the error, and the problem seems not to be the same with the popular errors at Ruby gem mysql2 install failing and mysql2 gem installation fails. These are the packages I've already installed for mysql.

First question: Has anyone got Rails mysql2 running with MySql 5.5.1 on Ubuntu? I have it running on another system with 5.1. The gem description is vague on supported MySql versions.
Second question: Has anyone encountered this problem? I± have battled various library issues with the mysql2 gem over the passed year or so but this seems to be different.
Any assistance is gratefully recieved.
BTW: Reverting back to MySql 5.1 is a valid solution!
Regards
Peter
Or just apt-get install libmysqlclient-dev and then gem install mysql2
So the problem appears to have been a missing library and some links. Doing the following solved the issue.
Get the new and install the libmysqlclient-dev deb package kindly provided by Nathan Rennie Waldock
wget http://ppa.launchpad.net/nathan-renniewaldock/ppa/ubuntu/pool/main/m/mysql-5.5/libmysqlclient-dev_5.5.24-1~ppa1~natty_amd64.deb./;l
dpkg -i libmysqlclient-dev_5.5.24-1~ppa1~natty_amd64.deb
Then create some links that mysql2 needs as it can't seem to follow the mysql path
cd /usr/lib/
ln -s /usr/local/mysql-5.5.24-linux2.6-x86_64/lib/libmysqlclient_r.a .
ln -s /usr/local/mysql-5.5.24-linux2.6-x86_64/lib/libmysqlclient_r.so .
ln -s /usr/local/mysql-5.5.24-linux2.6-x86_64/lib/libmysqlclient_r.so.18 .
ln -s /usr/local/mysql-5.5.24-linux2.6-x86_64/lib/libmysqlclient_r.so.18.0.0 .
Now happily install the mysql2 gem
sudo gem install mysql2

Had the same issue in Ubuntu 12.04 also using the ppa mentioned in the accepted answer.
But also there was no libmysqlclient file on my system with _r in the name.
Googling around I found out that package builders have started to drop the _r suffix from the files, so that might have happened between 11.10 and 12.04.
Also the paths were a bit different to the once mentioned so these are the symlinks that I had to create:
ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.a ./libmysqlclient_r.a
ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.so ./libmysqlclient_r.so
ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.so.18 ./libmysqlclient_r.so.18
ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.so.18.0.0 ./libmysqlclient_r.so.18.0.0
I had this problem as well...
I did dpkg -r mysql-devel as when I was trying to do apt-get install libmysqlclient-dev I got an error saying:
Unpacking libmysqlclient-dev (from .../libmysqlclient-dev_5.5.24-0ubuntu0.12.04.1_i386.deb) ... dpkg:

After doing this, gem install mysql2 worked! yay :)

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
I've tried everything here but I still get the error. For some reason when I run locate mysql_config this is the result I get:
/Applications/MAMP/Library/bin/mysql_config
/Applications/MAMP/Library/share/man/man1/mysql_config.1
I tried running sudo gem install mysql2 -- –with-mysql config=/path/you/identified/above/mysql_config twice using each path but I still get the error from above. I downloaded a fresh version of MySql and I have Xcode, but I still get these errors. What am I doing wrong?
Is the MAMP install the only install of mysql you have? If you've installed it from the mysql package then I think mysql_config will be installed in /usr/local/bin/mysql_config, so you might want to try:
sudo gem install mysql2 -- –with-mysql-config==/usr/local/bin/mysql_config
FYI, the /Applications/MAMP/Library/share/man/man1/mysql_config.1 path is clearly wrong. That's pointing to the man file for mysql_config not the actual executable.
Just to be certain, you did try this right? (exactly as written)
sudo gem install mysql2 -- –with-mysql-config=/Applications/MAMP/Library/bin/mysql_config
Also, I'm not sure that mysql packaged with MAMP has the header files you need. You might be best to install mysql from http://dev.mysql.com/downloads/mysql/ and then try to install your gem. In this case I think it will just work.
