We installed PHP with --with-mssql=/usr/local/freetds

So we're using all mssql commands in the code (ie. mssql_pconnect,
mssql_query, mssql_fetch_array).

I've tried changing various settings in the freetds.conf file. Switching TDS
versions between both 4.2 and 7.0. Tried adding/deleting "client charset =
UTF-8". But none of the changes appeared to effect my results.

I can't seem to get a real error message. Netscape gives me a pop-up "Page
contains no data". Safari errors, "Safari can't open the page." Opera never
loads or errors.

Apache gives me:
[Wed May 19 09:20:03 2004] [notice] child pid 1028 exit signal Bus error
(10)

Whenever I run a php page that works fine in the browser from cli php on the
command line it always errors "Call to undefined function:  mssql_connect()
... Segmentation fault (core dumped)". So I haven't been successful in
getting cli php to work.

Thanks for your help.
