ERROR: Error installing mysql: ERROR: Failed to create native gem extension

Question

I followed http://blog.mmediasys.com/2011/07/07/installing-mysql-on-windows-7-x64-and-using-ruby-with-it/ "to establish a connection between Ruby on rails app and mysql 5.1 server

Therefore, when I install gem mysql with the following command:

gem install mysql --platform=ruby -- --with-mysql-dir=C:/mysql-connector-c-noinstall-6.0.2-win32 

So, I get the following error log:

Temporarily increasing PATH to enable DevKit ...
Create your own extensions. This may take some time...
ERROR: Error installing mysql:
ERROR: Failed to create native gem extension.

Gem files will remain in C: /Ruby187/lib/ruby/gems/1.8/gems/mysql-2.9.1 for verification. Results recorded in C: /Ruby187/lib/ruby/gems/1.8/gems/mysql-2.9.1/ext/mysql_api/ge m_make.out

Additional information: Ruby version 1.8.7 Windows 7 64 bit Mysql 5.1 version

Answer 1

• Download the zip file with the mysql / C connector.

• Cancel the search in the specified C: drive folder.

• Copy the zip file with the connector libmySQL.dll from mysql/C

• try this command gem install mysql --platform=ruby - --with- mysql-lib=C:\mysql-C-connector\lib --with- mysql-include=c:\mysql-C-connector\include
