TinyXML #include problem... Using libraries - c++

Question

Hey, i'm really trying to get TinyXML to at least read a file but it says "main.cpp:8: error: ‘TiXMLDocument’ was not declared in this scope"
This is the code im using:
TiXMLDocument("demo.xml");
Ideally i want to read able to read files and output the XML so i also tried this code i found online in a tutorial
#include <iostream>
#include "tinyxml.h"
#include "tinystr.h"
void dump_to_stdout(const char* pFilename)
{
TiXmlDocument doc(pFilename);
bool loadOkay = doc.LoadFile();
if (loadOkay)
{
printf("\n%s:\n", pFilename);
dump_to_stdout( &doc ); // defined later in the tutorial
}
else
{
printf("Failed to load file \"%s\"\n", pFilename);
}
}
int main(void)
{
dump_to_stdout("demo.xml");
return 0;
}
And the errors I'm getting now are:
main.cpp: In function ‘void dump_to_stdout(const char*)’:
main.cpp:13: error: cannot convert ‘TiXmlDocument*’ to ‘const char*’ for argument ‘1’ to ‘void dump_to_stdout(const char*)’
If it helps im on a mac, ive tried compiling in terminal as well as textmate. I also tried to compile the cpp files for TinyXML separately before compiling main.cpp and i have no idea why i cant print out demo.xml let alone read it.

Answer 1

It's called TiXmlDocument, not TiXMLDocument
You can't call a function that you haven't declared yet. Since you're trying to call an undeclared overload of dump_to_stdout, the compiler assumes you want to call the version that takes const char * and fails.

Answer 2

dump_to_stdout( &doc ); // defined later in the tutorial
Here's your problem.
dump_to_stdout takes a const char* which TiXmlDocument is definitely not.
You're already in that function, so assuming the file loads you'll have infinite recursion.
It doesn't matter that you've got one defined later that takes a TiXmlDocument. At this point, the only dump_to_stdout that exists is the one you're in, hence the error. Forward declare the one you want before this function, e.g: void dump_to_stdout(TiXmlDocument*);
