Error[Li005]: no definition for "gsName" when trying to use DHCP

[jesperevertsson]

Hi, I'm trying to get the eth_to_serial MQX example to work with DHCP. It was no problem to make it work tiwh static ip, but when I try to use DHCP instead I get a linker error saying:

Error[Li005]: no definition for "gsName" [referenced from ipcfg.o(rtcs.a)]

Here is my code:

	_enet_address enet_addr = ENET_MAC;
	IPCFG_IP_ADDRESS_DATA ipData;

	ipData.ip = ENET_IPADDR;
	ipData.mask = ENET_IPMASK;
	ipData.gateway = ENET_IPGATEWAY;

	uint32_t status = RTCS_create();
	if (status == RTCS_OK)
	{
	status = ipcfg_init_device(BSP_DEFAULT_ENET_DEVICE, enet_addr);
	if (status == RTCS_OK)
	{
	//status = ipcfg_bind_staticip(BSP_DEFAULT_ENET_DEVICE, &ipData);
	status = ipcfg_bind_dhcp_wait(BSP_DEFAULT_ENET_DEVICE, FALSE, NULL);
	if (status == RTCS_OK)
	_task_create(0, UDP_TASK_INDEX, 0);
	}
	}

I managed to get it to work now by simply adding this code line to my main file.

char gsName;

Seems pretty stupid that this would solve the problem but it does. I have no clue though why this variable is required.

Hi Jesper,

What version of MQX and what development tool are you using?

I tested with MQX_4.1.1 on frdm-k64f using CW10.6 successfully.

Attached web_hvac demo project file rtcs.c is setup for DHCP and waits for Ethernet cable to be plugged in if it is not plugged in at reset.

I'm using MQX 4.1.1, twrk60 and IAREW.

I also just now saw this test in the ipcfg.h file: "RTCSCFG_IPCFG_ENABLE_DHCP must be set for DHCP"

Where do I set that? In user_config.h? Because right now that flag doesn't exist in my user_config.h file

[DavidS]

Hi Jesper,

The RTCSCFG_IPCFG_ENABLE_DHCP is defined in RTCS header rtcscfg.h and defaults to being enabled.

If you wanted to turn it off (i.e. disable it) then you could define it to 0 in the user_config.h header to override the default setting of 1.

BTW: Did you have a patch applied to the code for a WiFi vendor that might have included the gsName variable?

Regards,

David

I have no clue where the gsName comes from. I just modified the eth_to_serial MQX example and didn't include anything extra afaik
