Undefined reference to mysql while using cross-compiler

[hindus]

Hi, I’m trying to compile simple C++ program for Raspberry PI using cross-compiler method. I’ve done everything in the tutorial http://visualgdb.com/tutorials/raspberry/wiringPi/ and managed to run sample blinking led application, so everything seems to be configured ok.

Now I want to add some mysql support to log changes and read some config info.

#include 
#include <mysql/mysql.h>

int main(int argc, char *argv[])
{
    wiringPiSetup();

    MYSQL *mysql1 = mysql_init(NULL);


}

Unfortunatelly, I get en error:

‘NULL’ was not declared in this scope

I tried to include

#include <mysql/my_global.h>

so NULL was no longer undeclared, but another error showed:

error VGDB1000: undefined reference to `mysql_init’

What did I do wrong? Thanks!

Okay, I’ve found the solution. I was adding ‘mysql’ to ‘Library names’, but the correct name for mysql was ‘mysqlclient’. Everything works like a charm now 🙂

Good to know it works. If you encounter further problems, let us know.
