Ruby extension in C, LoadError

On my own computer I compiled a Ruby extension writen in C. Then I added require 'mytest/mytest' to my controller and it works. Then I moved the files to the server and when I start Mongrel I have the message that:

cannot open shared object file: No such file or directory - {path_to_file}/mytest.so (LoadError)

If I follow that path there is a file mytest.so.

The permissions on mytest.so are set to 0777 and full path is checked, still the same.

can not recompile becouse开发者_StackOverflow i don't have gcc on production serv.

Do you have any ideas?

It's probably different architecture, i.e. you had i386, and this is x86_64. Check with uname -a and file mytest.so

yeah you're probably going to need to recompile that binary extension--you can check for dependencies with the ldd command
