Hi

I recetly installed g++ on Fedora. (I used "yum install gcc-c++"). It seemed to be fine but if I try to compile the following very simple c++ code, it just gives me an error mesage sayng "expected constructor, destructor, or type conversion before < token"...

#include <iostream>
using namespace std;

int main()
{
cout << "Hello World \n";
return 0;
}

I'm a newbie and don't know what to do.. Please help me.

What is the command you're using to compile? The code looks fine to me. Edit: also, this should have been in the Programming forum.

Thanks for reply.

I used "g++ HelloWorld.cpp".

You should be using:

Code:

g++ SOURCE_FILE.CPP -o OUTPUT_FILE

Where SOURCE_FILE.CPP is the name of your source code, and OUTPUT_FILE is the executable. In the above example, you'd want this command:

Code:

g++ HelloWorld.cpp -o HelloWorld

Using "g++ HelloWorld.cpp" is fine, just the executable will be called a.out.

exactly...

"g++ filename.cpp -o filename" doesn't work either.

What are the compiler errors?

yea we need exact error messages copy and pasted

"expected constructor, destructor, or type conversion before < token" comes from the compiler. I found loads of similar errors when searching Google, but no way to fix them. Maybe his GCC is broken, or something.

Thanks heaps.

I just re-installed gcc and it's fine now.
