Hi, one short question: Why doesn't VS.Net 2003 compile this code:


		typedef struct tKeyName {
			
			std::string	   name;
			SDLKey		   sdlkey;
		} tKeyName;

		tKeyName KeyNames[] = {
		    
			{"a",           SDLK_a},
			{"LEFT",        SDLK_LEFT},
			{"RIGHT",       SDLK_RIGHT},
			{"UP",          SDLK_UP},
			{"DOWN",        SDLK_DOWN},
			{"ESC",         SDLK_ESCAPE},
			{"MOUSE1",      SDLK_WORLD_0},
			{"MOUSE2",      SDLK_WORLD_1},
			{"MOUSE3",      SDLK_WORLD_2},
			{"WHEELUP",     SDLK_WORLD_3},
			{"WHEELDOWN",   SDLK_WORLD_4},
			{"",            SDLK_LAST}
		};

This code compiles under gcc3. I get error C2059 and C2334. I would post the whole error messasge, but it isn't english :) Something like: unexpected token(s) preceding "{"; skipping visible function text Thanks for your help :)

Shouldn't it be

typedef struct{						std::string	   name;			SDLKey		   sdlkey;		} tKeyName;

That's how I've always seen it, though I'm not expert on this since I always use

struct x{...}

...just a thought

Stupid point maybe but i saw when looking up one of the error codes that someone had named the file .C instead of .CPP and got this problem, didn't specify which compiler though.

Another thought is shouldn't it be something like this:

typedef struct tKeyName {						std::string	   name;			SDLKey		   sdlkey;		} tKeyName;		tKeyName KeyNames[] = {		    			{std::string("a"),           SDLK_a},			{std::string("LEFT"),        SDLK_LEFT},			{std::string("RIGHT"),       SDLK_RIGHT},			{std::string("UP"),          SDLK_UP},			{std::string("DOWN"),        SDLK_DOWN},			{std::string("ESC"),         SDLK_ESCAPE},			{std::string("MOUSE1"),      SDLK_WORLD_0},			{std::string("MOUSE2"),      SDLK_WORLD_1},			{std::string("MOUSE3"),      SDLK_WORLD_2},			{std::string("WHEELUP"),     SDLK_WORLD_3},			{std::string("WHEELDOWN"),   SDLK_WORLD_4},			{std::string(""),            SDLK_LAST}		};

Try that ^^^

Okay, thanks for your help, but it didn'n work. And that double tKeyName was a typo :)

I don't know why, but you can't initialize structs this way in classes, don't ask me why :)

So, I changed the Code to this

//Input.h		typedef struct {						const char*	   name;			SDLKey		   sdlkey;		} tKeyName;		tKeyName *KeyNames;//Input.cppbool CInput::Init() {		static tKeyName sKeyNames[] = {		    		"a",           SDLK_a,		"LEFT",        SDLK_LEFT,		"RIGHT",       SDLK_RIGHT,		"UP",          SDLK_UP,		"DOWN",        SDLK_DOWN,		"ESC",         SDLK_ESCAPE,		"MOUSE1",      SDLK_WORLD_0,		"MOUSE2",      SDLK_WORLD_1,		"MOUSE3",      SDLK_WORLD_2,		"WHEELUP",     SDLK_WORLD_3,		"WHEELDOWN",   SDLK_WORLD_4,		"",            SDLK_LAST	};	KeyNames = sKeyNames;	return true;}

Looks really bad, huh :) But, let's hope it works.
