 Code:Blocks 16.01   SDL2-2.0.5    Windows 7    Mingw32

 I'm getting the error message "undefined reference to 'WinMain@16'
 I read about this in the net but couldn't resolve it?

 I can just click on "compile current file" the error is gone but if I "build" I get the error.
 Also I can comment out "#include <SDL.h> and it will "build" with no error.

Code:Blocks forum,

 Here's the information I left out in my original post.

 I am running Code::Blocks version 16.01 on Windows 7 Professional SP1
 The compiler I use is Mingw32 and search directories set to
 C:\SDL2-2.0.5\include\SDL.  There are no relative paths in my setup.

 When I build a simple "Hello World" program there are no errors and
 it runs successfully.  If I add #include <SDH.h> and try to build it
 again I get the error message 'undefined reference to 'WinMain@16'
 
 File name is main.cpp

#include <SDL.h>
#include <iostream>
using namespace std;

int main()
{
    cout << "Hello world!" << endl;
    return 0;
}

 OTHER THINGS I HAVE TRIED

 There was a suggestions on the web regarding placing -mwindows as compiler
 flag which you can see in the Build logs.

 Select the checkbox  in Settings-> Compiler > Build options "Explicitly add currently compiling file's directory to compiler search dirs".

 Closing and reopening Code:Blocks.

 Go to project > build option and put a check mark on "Have g++ follow the C++11 ISO C++ language standard [-std=c++11]".

 project --> build option Put check mark on " Have g++ follow the C++11 ISO C++ language standard [-std=c++11]"


 Any suggestions?

PLEASE READ YOUR OTHER THREAD or I will ask for you to be banned!!

Follow this link if you are NOT a troll; if you are a troll get lost!

Edit: Sorry, at first reading it looked like you were a newbie, who failed to read the replies to your first post.
But, you are just a newbie who starts new threads for no reason, instead.

I suggest you fix the main function to match what is on the link below look up one FAQ.

What you should have

--- Code: ---int main(int argc, char *argv[])

--- End code ---
