You need to install the Sybase OpenClient libraries.

You can download a free version of OpenClient from Sybase, or depending on the licence you have for the Solaris version you can get the more recent 11.1.1 or 12.5 libraries (which aren't free, but can still be downloaded for free trials.)

For the 11.1.1 or 12.5 version you need the "common" and the "openclient" rpms. For the free 11.0.3.3 version you'll need to download both rpms (server and client).

Remember to create a correct interfaces file on the linux side - the default Solaris TLI format will not work on linux, so the easiest thing to do is to use "sybinit" (in the 11.0.3.3 release) or "dsedit" (for the more recent versions) to create the appropriate interfaces file entries.

Good luck!
