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
