><SPAN
CLASS="PRODUCTNAME"
>SybSQL</SPAN

CLASS="PRODUCTNAME"
>SybSQL</SPAN
> to find <SPAN
CLASS="PRODUCTNAME"
>Qt</SPAN
> and <SPAN
CLASS="PRODUCTNAME"
>FreeTDS</SPAN
> you need to define <CODE
CLASS="ENVAR"
>QTDIR</CODE
> and <CODE
CLASS="ENVAR"
>SYBASE</CODE
> environment variables.  If you have <SPAN
CLASS="PRODUCTNAME"
>Qt</SPAN
> installed, you may have <CODE
CLASS="ENVAR"
>QTDIR</CODE
> defined already.  To verify, type <B
CLASS="COMMAND"
>echo $QTDIR</B
> at the shell prompt.  This example uses my own installation path of <TT
CLASS="FILENAME"
>qt-2.3.1</TT
> (from RedHat 7.2), YMMV.

><P
>One caveat to the way in which <SPAN
CLASS="PRODUCTNAME"
>SybSQL</SPAN
> and <SPAN
CLASS="PRODUCTNAME"
>FreeTDS</SPAN
> interact is that <SPAN
CLASS="PRODUCTNAME"
>SybSQL</SPAN
> expects to be running under <SPAN
CLASS="PRODUCTNAME"
>OpenClient</SPAN
>, and makes the assumption that a valid <CODE
CLASS="ENVAR"
>$SYBASE</CODE
><TT
CLASS="FILENAME"
>/interfaces</TT
> file exists.  Since <SPAN
CLASS="PRODUCTNAME"
>FreeTDS</SPAN
> has deprecated use of the <TT
CLASS="FILENAME"
>interfaces</TT
> file in favor of the <TT
CLASS="FILENAME"
>freetds.conf</TT
> config file, you may have to create a <TT
CLASS="FILENAME"
>interfaces</TT
> file just to satisfy <SPAN
CLASS="PRODUCTNAME"
>SybSQL</SPAN
>.</P
><P
>By defining <CODE
CLASS="ENVAR"
>SYBASE</CODE
> to the parent directory of the <TT
CLASS="FILENAME"
>interfaces</TT
> file, you may put it wherever you like; it does not have to be in <TT
CLASS="FILENAME"
>/usr/local</TT
>.  When using <TT
CLASS="FILENAME"
>freetds.conf</TT
>, <SPAN
CLASS="PRODUCTNAME"
>FreeTDS</SPAN
> does not rely on the <CODE
CLASS="ENVAR"
>SYBASE</CODE
> variable for finding its own components, so it is safe to point it elsewhere.</P
