Runtime Configuration of MAC Address

Thanks for the info,
But the code complains about
main.c(18): error: #70: incomplete type is not allowed

this is my code

extern struct ETH_CFG eth0_config;

uint8_t mac_adr[6] = { 0,1,2,50,60,70 };

int main(void)
{


        memcpy (eth0_config.MacAddr, mac_adr, 6);
        // Initialize the Network Core
        net_initialize ();
        while(1)
        {
        }
}

        {
        }
}

And your next step then was to scan through all header files, checking if any header file contained ETH_CFG?

Thanks for the info, Actually I have found it on #include "rl_net_lib.h"

But no matter if I include it in my main code,I still got the same error,

Also if I include #include <net_config.h> the code generates another error

C:\Keil_v5\ARM\PACK\Keil\MDK-Middleware\6.4.0\Network\Include\net_config.h(27): error: #35: #error directive: "::Network:Interface: No interface enabled in configuration" #error "::Network:Interface: No interface enabled in configuration"

I do not real not know what am I doing wrong.
