Paint pixels in c++

Asked

Hello, I needed a function to paint pixels on the console.
I came up with a solution here but when compiling gives me the following mistake:

C: Users user user Appdata Local Temp ccORhjHu. o:test.cpp:(.text+0xa1): Undefined Reference to `Setpixel@16'
collect2.exe: error: Ld returned 1 Exit status

I would like to be provided with a way to correct this mistake or another way to do the same thing.

Note: I use windows 7 32-bit, with mingw c++ installed

    You included the libgdi32.a in the compilation (with -lgdi32)?

  • I include this flag but gives another error. Gives this error: Undefined Reference to 'Std::ios_base::Init::Init()'

  • What is the complete command you are using to compile?

  • gcc filename.cpp -lgdi32 and includes unistd. h library and replaces cin.ignore(); for sleep(5); because I was making a mistake

  • Isn’t the program in C++? If it is, the line should be g++ filename....... The gcc is for C programs, not C++

  • Thank you very much! It worked, just one thing, gcc should work because cpp is C Plus Plus (C++). I could turn that comment into an answer to mark it as correct?

According to the comments, the error was corrected after including the GDI32 lib (libgdi32.a), where the function is located SetPixel.

The mistake:

undefined reference to 'std::ios_base::Init::Init()'

occurred due to the use of the compiler gcc (used to compile programs in C).

The correct compiler for the C++ language in the package Mingw32 is the: g++.
