How are you invoking gcc? Can you copy-and-paste the command line you used?

I would like to be able repro this on my machine otherwise it's very hard to fix.

[MaciejJezierski]

As you didn't provide any command I should use and I am using visual studio code where I have specified build path to folder with source code and your print.h I am using just "g++ myprogram.cpp". (tried with gcc too, still same errors)

[adob]

If you have a source file that looks like this:

// basic_example.cpp
#include "print.h"

int main() {
    print "hello world";
}

you should be able to compile with g++ basic_example.cpp and it should work?

This doesn't work for you? This works for me on Linux but I don't have a Windows machine to try this on.

[MaciejJezierski]

It shouldn't be problem but especially for you I wrote your example and I still get same errors. I am on MacOS but as it is unix based it shouldn't be problem too. Also I tried to compile it with all versions of g++.

i cant see my information ppl stole it
