Hi all
I am trying to access mysql through a c program, bt am stuck with a specific error. I have searched the net for solutions, but nothin helped
Code:
/* Simple C program that connects to MySQL Database server*/
#include <mysql.h>
#include <stdio.h>
main() {
MYSQL *conn;
MYSQL_RES *res;
MYSQL_ROW row;
char *server = "localhost";
char *user = "root";
//set the password for mysql server here
char *password = ""; /* set me first */
char *database = "mysql";
conn = mysql_init(NULL);
/* Connect to database */
if (!mysql_real_connect(conn, server,
user, password, database, 0, NULL, 0)) {
fprintf(stderr, "%s\n", mysql_error(conn));
exit(1);
}
/* send SQL query */
if (mysql_query(conn, "show tables")) {
fprintf(stderr, "%s\n", mysql_error(conn));
exit(1);
}
res = mysql_use_result(conn);
/* output table name */
printf("MySQL Tables in mysql database:\n");
while ((row = mysql_fetch_row(res)) != NULL)
printf("%s \n", row[0]);
/* close connection */
mysql_free_result(res);
mysql_close(conn);
}
The command i used to compile the program is:
gcc -o connectsql $(mysql_config --cflags) connectsql.c $(mysql_config --libs)
Error:
/tmp/ccx4qAGm.o: In function `main':
connectsql.c: (.text+0x13f): undefined reference to`mysql_free_results'
collect2: ld returned 1 exit status
