Hi, I have finally given up and am desperately hoping for some help. I have developed rails using MySQL-5.0.20a-nt. The application run without any problem in developement environment. Now unfortunately in production I have MySQL-4.1.11. Same application I try to run in production (with mysql 4.1.11) it crashes with the following error. I have no clue why it is doing that. I have been searching for the answer without any luck. I did install mysql.so from(<http://rubyforge.org/frs/?group_id=477>). Then I got "The application has failed to start because LIBMYSQL.dll was not found. Re-installing the application may fix this problem" so I have copied the IBMYSQL.dll from mysql5.0/bin to WINDOWS/SYSTEM32 dir. Error: /ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/inflector.rb:160: [BUG] Segmentation fault ruby 1.8.4 (2005-12-24) [i386-mswin32] The database schema is same as used in development. Any help will be greatly appreciated. Thanks -- Posted via http://www.ruby-forum.com/.
