Hi,  
I have mysql installed on linux. Whenever I am trying t  
“gem install mysql – --with-mysql-dir=/usr/bin/mysql”  
I am getting following error:-

Building native extensions. This could take a while…  
ERROR: Error installing mysql:  
ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of  
necessary libraries and/or headers. Check the mkmf.log file for more

Gem files will remain installed in

/usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/ext/mysql\_api/gem\_make.out

Can anyone tell me how to solve this?  
Thanks,

Hi,  
I solved the issue.  
I forgot to install “mysql-delop” client.  
My problem I was working on windows since last 2 years. I moved to linux  
now and I am facing lot of problem for installation. I don’t why the  
installation process for platforms is different as well as cumbersome to  
install.

Anyone have any answer on this.  
Thanks,  
Tushar
