I have the following declarations:
and i get dereferencing pointer to incomplete type error where the arrow is. Any ideas?Code:typedef struct SymbolEntry_tag * SymbolEntry; struct SymbolEntry_tag { Identifier id; Scope scope; SymbolEntry nextInHash; SymbolEntry nextInScope; Type type; }; SymbolEntry symbolentry; (symbolentry->type) = ... <------
What is Type?
7. It is easier to write an incorrect program than understand a correct one.
40. There are two ways to write error-free programs; only the third one works.*
Code:typedef struct Type_tag * Type; struct Type_tag { enum { TYPE_unit, TYPE_bool, TYPE_char, TYPE_int, TYPE_float, TYPE_array, TYPE_ref, TYPE_func, TYPE_id } kind; union { struct { int dim; Type type; } t_array; struct { Type type; } t_ref; struct { Type type1; Type type2; } t_func; struct { Identifier id; } t_id; } u; };
Is symbolentry pointing to an object?
[edit]Is your ... a pointer to a valid struct Type_tag object?

first of all it is a valid struct Type_tag object. secondly i put the ... in the next line and i get the error on the line where the (symbolentry->type) is
Well, there is not enough context for me to even attempt to reproduce any similar diagnostic message. I'll quit.

I'll give you one post worth:
Is Type_tag declared before or after SymbolEntry_tag, or, are they even able to see eachother in scope? An "incomplete type" error means that you're trying to use an object which has not been defined any place. This would be akin to the following:
Here, we have no idea what "struct bar" contains, because it's not defined anywhere. That's what you've got. Since you've just pasted in random definitions for us, and haven't actually shown us the real file you're working with, this is as good as it's going to get.Code:struct foo { struct bar *baz; }; struct foo f->baz->something = somethingelse;
You are trying to use "type", without that structure being available to it in any scope. Declare it before you try to use it, so that it knows what "type" contains.
Also, in the future, don't replace stuff with "...". It might actually help someone in the future to see what it is you were trying to assign there, rather than just "...".
Quzah.
Hope is the first step on the road to disappointment.
i m working with six header files and six source files, thats why i couldn't post it all. I was hoping for a short easy answer. it must be a scope thing which i can't sort out.
Well there you go. You're trying to use a structure whose header you have not included.
