Note that the MySQL client library is not bundled anymore. Solved!
January 31st, 2010
This error is not specific to Litespeed but can be encountered while building PHP with MySQL support on 64-bit systems. The fix is to tell the build that the MySQL client is indeed installed, but in a different directory, by adding the following flag to the configure line in Litespeed:
--with-libdir=lib64
The reason being the build doesn’t know at this point that it is dealing with a 64-bit OS. If adding the above switch does not work, be sure to install the MySQL client and libraries.
That’s all folks!
