Help Arduino IDE stupidness.

phoenixcomm

Today's problem is that I am working with "CANNED" messages so in C I use an array or structures like this: 

struct messages{
int display;
char* message[9];
};
typedef struct messages Messages[] = {
{1, "BITE TST"}, { 2, "NO LNIK"}, {2, "NO ERROR"},
{1, "AVIONICS"}, { 2, "COMM OK"}, {2, "ER-"},
{2, "LB-"}, {2, "GL-"}
};

but the IDE error: typedef ‘Messages’ is initialized (use decltype instead)  WTF!!!!????

I have also re-written this as:

typedef struct {
int display;
char* message[9];
}Messages [] = {

{1, "BITE TST"}, { 2, "NO LNIK"}, {2, "NO ERROR"},
{1, "AVIONICS"}, { 2, "COMM OK"}, {2, "ER-"},
{2, "LB-"}, {2, "GL-"}
};

OK, I give up! Please can anybody quickly tell me what the heck is going on??

    You can't assign values to a typedef. Declare a variable of that typedef, and assign values to it.

    If you're using the Arduino library, you might want to use its String object instead of C-char arrays. https://www.arduino.cc/reference/en/language/variables/data-types/stringobject/ You have to be…
