Linux talking to MS SQL

Hello- I know I have seen this thread fly around once in a while, so here it goes again. I have a Red Hat where I am using the php executable to run scripts on the server. Specifically FTP scripts. I would like to be able to put a web front end on this so the users can configure it, but I am not allowed to use MySQL yet, since it is offically unsupported at my company. I am allowed to use the MS Sql Server though. I know I can connect to the MS Sql server via Win32, but I am trying to connect via Linux. I downloaded FreeTDS. Here is what I use to compile it: ./configure --enable-ftp --enable-sybase=/usr/local/freetds/lib Yet after I make and install I run /usr/local/bin/php -m and Sybase is not listed as a module. Thoughts? Thanks, -Scott
