odbc in linux?

Hi, i'm developing a web system in webdeb languaje and my databases are informix, my tool (webdev) is running on windows, so i have installed informix client on my pc, i declared all the odbc's i need (from several databases on diferent servers) and the tests are fine

The final application is going to be hosted on a linux server, and i have not experience with linux

My question is:
odbc works same way in linux and windows?
or, what's the "equivalent" of work with odbc in linux?

any tips, info links, manuals, etc?

regards
