Subject:[mysql] compile and ikage problem still :(
View as plain text  
Hi again,
	Let me try this again and give everyone more information on my problem.  As I
have tried the other suggestions but still the same problem.  I think I am not
able to link the correct files with my simple code.  All I want to do now is
at lest connect to MySQL database with my C program.  I was told to use the
mysqlbug program but I don't know how, but I did find it though.  So here is
as much information I can think of to give.

Server Software: FreeBSD 2.2.7
MySQL version:  3.21.33b
Compiler: gcc version 

Code I wrote:

#include<stdio.h>
#include<stdlib.h>
#include"/usr/ports/databases/mysql321/work/mysql-3.21.33b/include/mysql.h"
     //  if I put in #include"mysql.h" the compile can't link the files even
when I supply     //the path to it with the -l flag.

MYSQL mysql;

void exiterr(int exitcode)
{
        fprintf( stderr, "%s\n", mysql_error(&mysql) );
        exit( exitcode );
}

int main()
{
  mysql_init();

        if ( ! (mysql_connect(&mysql,"NULL","NULL","NULL")))
               exiterr(1);

        if (mysql_select_db(&mysql,"test"))
                exiterr(2);

}

So how do I do this?  How do I use mysqlclient lib?  What do I do.  I am very
confused.  How do I create a proper debugger report for you guys also.

Thank you very much for the help,
