I'm getting compiler errors when compiling the NDS homebrew SDK for Wmb Asm.(With devkitARM. I'm posting here because I got zero help with these errors on a DS homebrew forum) Errors:

That "bool" enumeration definition is weird. It should be typedef enum { ... } bool instead, otherwise you'd need the namespace qualifier "enum bool" everywhere.

Thanks. After changing that, and pre-appending numerous structs in front of references to structs/code using structs, the SDK compiled successfully for DS. Kind of. I got one warning reporting that fat.h could not be found. Shouldn't impact anything, as the structs/prototypes in the fat.h header aren't really used in the SDK. That should be fixed anyway, though. I'll add the usual (SOLVED) note in the title of this thread once I get the rest of Wmb Asm compiled for DS.

Don't. There is no need: a "solved" post will eventually fall off the recent thread list anyway. IMO, "solved" can do more harm than good. Consider a beginner, who gets a workable but imperfect solution to their question. Is the question solved? I think not.

@rip-off:
Okay... I used to do that here because on much smaller forums, that's what people did when the problem is solved. I program in Cpp mainly. I hardly ever use C, mainly because of those obscure compiler errors, so I have a hard time fixing some C errors, like these errors in this thread.(Iirc, errors with structs were the main errors I had the most trouble with. But with other errors, I don't really have as much trouble with those.)

Are you referring to:
Quote:

Or the enum bool issue?(I guess it's most likely the former...)

So, when defining structs in C, how am I supposed to define structs, with typedefs? And can work with linked lists? I got a lot of compiler errors when attempting to use typedef and linked lists with structs.(Errors on every attempt to fix those errors) For the "normal" usage, I tried changing one struct from struct mystruct {...} __attribute__ ((__packed__)); To typedef struct {...} __attribute__ ((__packed__)) mystruct; I also tried placing mystruct back where it was, after the struct, and keeping an altered typename after the struct, and adding the old typename at the end, but I got incomplete type compiler errors.

I am not referring to anything in this thread in particular - I just think that the practise of marking threads as "solved" itself is flawed, and can be detrimental to the community as a whole.

The idea is discussed here.

The situation I gave was a hypothetical one - indicating one reason I dislike the idea of marking threads as "solved".
