| how do you resolve this error? util.c:10: warning: its scope is only this definition or declaration, which is probably not what you want I have something like this: Code: void print(struct ExprNode *root, int nLevel){
............
........
}

| Sounds like you have a typo - or you are using C++, so you shouldn't have "struct" in the function definition, perhaps? Alternatively, there may be macros at play. -- Mats

| So how is that struct declared in the tree.h file? The compiler thinks you are declaring it in the function parameter list. |

| here's the struct located in the tree.h file: Code: struct ExprNode {
ExprType type;
struct ExprNode *next;//used for parameter exprList r;
struct ExprNode *prior;//used for parameter list
struct ExprNode *parent;//or the son exp
struct ExprNode *left; //used for any expression element, array,
struct ExprNode *right;
struct ExprNode *StmtDomain[4];
//it is used for statment and function body
char* name;// name for function and Identfier
int n;
int nodeSeen;
int tempVarCount;
int rootLabelCount;
/*static void print(ExprNode *p,int n);
static void printTab(int n);//print n tabs*/
};

| What are the first 10 lines of util.c Do you include tree.h ? Does tree.h have #ifndef GUARD #endif constructs? Are those constructs unique to every single include file, or did you just copy/paste them? Oh, and you're writing C++ at this point.

| I am actually a C programmer, and not familiar at all with C++.. I just need to fix this code somehow.. can you guys tell me why it's a C++ program? maybe it's because I am compiling it with gcc that's why it's complaining? |

| Because structs cannot contain functions...

| so how would you translate such thing to C? are you trying to say the reverse? functions cannot contain struct as arguments? |

There are trickeries and hacks that can make it possible, but otherwise than that, there is no solution because C is a procedural language. What you are looking at is OOP. C++, Java, C#, etc-

| okay lets just fix this code then.. do you compile a C++ file the same as a C file? using gcc -o util.o util.c , something like that? |
