CImg compilation errors in CodeBlocks 17.12

I'm trying to work with CImg library, but I constantly get compilation errors, so I'm not able to find out if my programs would use this library correctly. I've started with the default code just for testing:

#include <iostream>
#include "CImg.h"
using namespace std;
int main()
{
cout << "Hello world!" << endl;
return 0;
}

After compiling, I get the following errors:

6205|error: '_fileno' was not declared in this scope

In function 'FILE* cimg_library::cimg::win_fopen(const char*, const char*)':

|59832|error: '_wfopen' was not declared in this scope|

How can I get this to work properly? I use gnu++11 compiler (as it was said in Compiling CImg with c++0x and MingW ) but it still does not work.

Done, but I still get scope error for `_fileno` – user9507446 Oct 05 '18 at 12:32

Please show the commands used to compile. – Mark Setchell Oct 05 '18 at 15:37
Try adding `#define _POSIX_C_SOURCE 200809L` as the very first line of your code. – Mark Setchell Oct 05 '18 at 15:47
Did you manage to solve this? – Mark Setchell Oct 14 '18 at 11:09
@MarkSetchell no, I changed the IDE – user9507446 Oct 15 '18 at 09:24
If you need to troubleshot the problem under Code::Blocks, you have to show use the full build log, see here: [1 Q: How do I troubleshoot a compiler problem?](http://wiki.codeblocks.org/index.php/FAQ-Compiling_(errors)#Q:_How_do_I_troubleshoot_a_compiler_problem.3F) – ollydbg23 Oct 21 '18 at 04:54
