yvesdm3000:
A wild guess, your file has ".c" as an extension and not ".cpp" ? Using <iostream> is strictly C++

The program code is at the bottom.
These compile/build errors (only the first few) are in memoryfwd.h:

The code is:
#include <iostream>

using namespace std;

int main()
{
cout << "hello world\n";
return 0;
}

stahta01:
Name the program file with the correct file extension instead of using the name "hello.c" try using "hello.cpp".

I created a new project and named the source hello.cpp. On build I got these errors:

collect2.exe: error: ld returned 1 exit status
Process terminated with status 1 (0 minute(s), 3 second(s))
5 error(s), 0 warning(s) (0 minute(s), 3 second(s))

I've set the 5 error messages to bold and italic.

thanks

msm98lw:
I found ld.exe in C:\Program Files (x86)\CodeBlocks\MinGW\mingw32\bin and added that path to the global compiler settings. I got the same result except this time there were 6 errors.

Thanks
