mysql_init（）始终返回null

Question

I have this very short program. For some reason mysql_init always returns null for me. According to the documentation, this happens if there isn't enough memory. How can this be? It's just these few lines of code.

#include "mysql.h"

int main()
{
    MYSQL * mysql;
    mysql = mysql_init(0);
    // here mysql is 0
    return 0;
}

I use Visual Studio 2015 and the lib from mariadb-10.1.8-win32.zip .

edit: I made it work a bit. I was compiling with debug Settings in visual Studio and linked to libmysqld.lib. I also copies libmysqld.dll in the work dir. That resulted in the ffect I describe above. I tried to link to libmysql.lib and copies libmysql.dll to the work dir and that worked. I don't plan to debug mysql code, so I can live with that. It's still strange though why the debug lib doesn't work for the same code.

Answer 1

if you link with libmysqld.lib, mysql_init will return NULL or crash. I test on mysql5.6 5.7 win10 vs2017.

the correct is libmysql.lib.
