reason for "error: expected '=', ',', ';', 'asm' or '__attribute__' before '.' token"

[HEckardt]

Dear Forum Members,

I defined/declared a struct "udp_buf_t" as "rx_tx_buf":

Code: Select all

typedef enum
{
	LAN_BEGIN,
	START_WPS,
	LAN_FOUND,
	LAN_NOT_FOUND,
	BROADCAST_SEND,
	HE_MON_FOUND,
	HE_MON_NOT_FOUND,
	MSG_TO_SEND,
	WAIT_FOR_ANS,
	GOT_HE_MON_ANS,
	MAIN_IDLE
}ctrl_lan_state_t;


typedef struct
{
	char rx_buffer[64];
	char tx_buffer[64];
	ctrl_lan_state_t lan_state_ctrl;
	struct sockaddr_in sauna_mon_adr;
}udp_buf_t;

	udp_buf_t rx_tx_buf;
	
	rx_tx_buf.sauna_mon_adr.sin_family = AF_INET;  	// row 104
	rx_tx_buf.sauna_mon_adr.sin_port = htons(3333);	// row 105
	rx_tx_buf.lan_state_ctrl = MAIN_IDLE;			// row 106

but when I want to build it, I get this error messages from "idf.py":

C:/ESP32_Projects/Sauna_Ctrl/main/he_lan_part.h: At top level:

I`m quite sure, I use the correct sytax in the rows 104, 105, 106. So, what could be made wrong?


Thank you for your support.

Are you putting those assignments outside of a function? You can't really do stuff like that globally.

Hi ESP_Sprite,

yes, you are right, I did it globally. Thank you for the hint. I`ll assign the values inside a function.
