You should put these commands into a shell start-up file such as <TT CLASS="FILENAME" >/etc/profile</TT > or <TT CLASS="FILENAME" >~/.bash_profile</TT >. Some good information about the caveats associated with this method can be found at <A HREF="http://xahlee.org/UnixResource_dir/_/ldpath.html" TARGET="_top" >http://xahlee.org/UnixResource_dir/_/ldpath.html</A >. </P ><P > On some systems it might be preferable to set the environment variable <TT CLASS="ENVAR" >LD_RUN_PATH</TT > <SPAN CLASS="emphasis" ><I CLASS="EMPHASIS" >before</I ></SPAN > building. </P ><P > On <SPAN CLASS="SYSTEMITEM" >Cygwin</SPAN >, put the library directory in the <TT CLASS="ENVAR" >PATH</TT > or move the <TT CLASS="FILENAME" >.dll</TT > files into the <TT CLASS="FILENAME" >bin</TT > directory. </P ><P > If in doubt, refer to the manual pages of your system (perhaps <TT CLASS="COMMAND" >ld.so</TT > or <TT CLASS="COMMAND" >rld</TT >). If you later get a message like: </P><PRE CLASS="SCREEN" >psql: error in loading shared libraries libpq.so.2.1: cannot open shared object file: No such file or directory</PRE ><P> then this step was necessary. Simply take care of it then. </P ><P > If you are on <SPAN CLASS="SYSTEMITEM" >Linux</SPAN > and you have root access, you can run: </P><PRE CLASS="PROGRAMLISTING" >/sbin/ldconfig /usr/local/pgsql/lib</PRE ><P> (or equivalent directory) after installation to enable the run-time linker to find the shared libraries faster. Refer to the manual page of <TT CLASS="COMMAND" >ldconfig</TT > for more information. On <SPAN CLASS="SYSTEMITEM" >FreeBSD</SPAN >, <SPAN CLASS="SYSTEMITEM" >NetBSD</SPAN >, and <SPAN CLASS="SYSTEMITEM" >OpenBSD</SPAN > the command is: </P><PRE CLASS="PROGRAMLISTING" >/sbin/ldconfig -m /usr/local/pgsql/lib</PRE ><P> instead. Other systems are not known to have an equivalent command. </P ></DIV ><DIV CLASS="SECT2" ><H2 CLASS="SECT2" ><A NAME="AEN25494" >15.5.2.

If you are going to run client applications remotely then it is convenient if every user that plans to use the database sets <TT CLASS="ENVAR" >PGHOST</TT >. This is not required, however; the settings can be communicated via command line options to most client programs. </P ></DIV ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="install-procedure.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="supported-platforms.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Installation Procedure</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="installation.html" ACCESSKEY="U" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Supported Platforms</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
