Hello again folks.  This oughtta be easy, but then again...I'm trying to
use the MySQL C API to access a database.  Seems easy enough.  Here's a
(non-useful) program snippet:

-------snibegin------
  #include <stdio.h>
  #include <mysql.h>

  main()
  {
    MYSQL  MySQL;  
    mysql_connect(&MySQL, "mrbill", "bill", "metekake");
  } /* main */
-------sniend---------

The header file (mysql.h) has the declaration:

  MYSQL *mysql_connect(MYSQL *mysql, const char *host,
                       const char *user, const char *passwd);
I try, and get:

  MrBill:~/db/src$ cc -I/usr/local/include/mysql -L/usr/local/lib/mysql
-lmysqlclient tryme.c
  /var/tmp/ccSBG4211.o: Undefined symbol `_mysql_connect' referenced
from text segment

The MySQL docs say I need to add a -lm library as the last linked lib,
but that does not help.  The compiler checks the mysql header, because
syntax or type errors halt compilation.  The lib seems OK:

  MrBill:/usr/local/lib/mysql$ strings libmysqlclient.a | grep connect
  _mysql_real_connect
  _mysql_connect
  _mysql_reconnect
  _mysql_real_connect
  _remember_connection
  _mysql_connect
  _connect

This oughtta be easy.  Have I lost my mind?

Thanks
-Glen
