I'm running on a Mac OS Leopard (10.5.8). I was able to download a dev kit from the Apple site which is the only one compatible with my system. The problem is the compiler doesn't work properly (so I assume). I tried compiling a simple C++ Hello World program and it gives me error messages. I believe I have GCC 4.0 if I'm not mistaken. I tried Google for answers but I haven't found any solution. Any form of help would be greatly appreciated. :)

Error message when I compile (using "gcc Hello.cpp -o Hello") in Terminal:


Undefined symbols:

Would you please post your code also?

Here it is. I followed a book so I doubt the problem lies in the code though.

#include <iostream>


/*Hello::Hello() {

	// TODO Auto-generated constructor stub


}


Hello::~Hello() {

	// TODO Auto-generated destructor stub

}*/


int main(){

	std::cout << "Hello World!\n";

	return 0;

}

Well! As you have commented the code:

/*Hello::Hello() {

	// TODO Auto-generated constructor stub


}


Hello::~Hello() {

	// TODO Auto-generated destructor stub

}*/

So, there doesn't seems any problem with it.

I guess, the problem is in,

Quote

gcc Hello.cpp -o Hello

.
You must use:

g++ Hello.cpp -o Hello

Hope this Helps!

Typo!

[Heartcubes]

Thank you very much! I tried it but unfortunately the command doesn't exist. :(

[AKMafia001]

Maybe because it would not be installed. The installation would be quite simple. Try it.

[Heartcubes]

Is there a tutorial on how to do that?

[AKMafia001]

You can google it. Well! Why don't try Xcode on Mac?

[Heartcubes]

I already tried IDEs. Xcode and Eclipse won't run it either.

I agree that you need to use g++ instead of gcc. I have the same OS and I installed the free version of Xcode (I believe it is the previous year's release) and g++ works for me. I would try to reinstall xcode since gcc and g++ should be included with xcode. Also, once you install Xcode, you would still compile and run the program in the terminal

G++ is for C++ and GCC is for C.
