How To Compile With Dev C++

PS: This was published on my Blog here.

C++ is a statically-typed, free-form, (usually) compiled, multi-paradigm, intermediate-level general-purpose middle-level programming language.

Dec 06, 2016  I am trying to write a program in C using Dev-C 5.6.1. I go to compile the program, and nothing happens. It compiles with zero errors, zero warnings, and an output of 0 bytes (it doesn't even create an exe file, nor any of the.o files).

In simple terms, C++ is a sophisticated, efficient, general-purpose programming language based on C.

It was developed by Bjarne Stroustrup in 1979.

One of C++'s main features is the compiler. This is used to compile and run C++ code.

A compiler is a special program that processes statements written in a particular programming language like C++ and turns them into machine language or 'code' that a computer's processor uses.

I actually wrote this article because I had a C++ assignment which required using a compiler. As usual, everyone was using the CodeBlocks IDE and Visual Studio IDE. But I was already used to Visual Studio Code for all my programming stuff.

I then set out to find a way of compiling C++ directly inside my own VsCode Editor, hence this article :).

In this article, I'll show you how to set up your compiler in VsCode and give you some links to some of the best C++ resources.

  • Prior knowledge of C++
    (I assume you're learning C++, about to start learning, or just reading this for fun. This article is not a C++ 101 tutorial – some understanding of C++ is needed.)
  • Visual Studio Code Editor
    Download here and read the setup docs for Windows, Linux and Mac
  • Internet connection (!important)

Disclaimer!

I will be using a Windows OS throughout this article, but I'll provide links to resources that will help those using other operating systems.

Now let's get started!

  • Head to www.mingw.org and click the “Download/Installer” link to download the MinGW setup file, or click here for Windows, here for Linux, and here for Mac
MinGW, a contraction of 'Minimalist GNU for Windows', is a minimalist development environment for native Microsoft Windows applications.
  • After downloading, install MinGW and wait for the “MinGW Installation Manager” to show up.

  • When the “MinGW Installation Manager” shows up, click on mingw32-gcc-g++ then select “Mark for Installation”
  • In the menu at the top left corner, click on “Installation > Apply Changes”
  • Wait and allow to install completely. Ensure you have a stable internet connection during this process.

PATH is an environment variable on Unix-like operating systems, DOS, OS/2, and Microsoft Windows, specifying a set of directories where executable programs are located. In general, each executing process or user session has its own PATH setting. - Wikipedia

After installing MinGW, it can be found in C:MinGWbin. Now you have to include this directory in your environment variable PATH. If you've been using computers for a while now you should know how to do this already, but if you don't, here are a few resources:

  • Click here for Linux
  • Click here for a Mac OS guide

Now we have our compiler set up, let's install Code Runner

Code Runner allows you to Run code snippet or code file for multiple languages:

C, C++, Java, JavaScript, PHP, Python, Perl, Perl 6, Ruby, Go, Lua, Groovy, PowerShell, BAT/CMD, BASH/SH, F# Script, F# (.NET Core), C# Script, C# (.NET Core), VBScript, TypeScript, CoffeeScript, Scala, Swift, Julia, Crystal, OCaml Script, R, AppleScript, Elixir, Visual Basic .NET, Clojure, Haxe, Objective-C, Rust, Racket, AutoHotkey, AutoIt, Kotlin, Dart, Free Pascal, Haskell, Nim, D, Lisp, Kit, and custom command.
  • Click here to download
  • Or search in VsCode marketplace tab
  • After installing restart VsCode
  • Open your C++ file in Vscode. Here's a basic hello world program below:

Save this file as test.cpp

How To Compile Header Files In Dev C++

  • Use the shortcut Ctrl+Alt+N
  • Or press F1 and then select/type Run Code
  • Or right-click the Text Editor and then click Run Code in the editor context menu

The code will run and the output will be shown in the Output Window. Open the output window with `Ctrl+ shortcut.

  • Use the shortcut Ctrl+Alt+M
  • Or press F1 and then select/type Stop Code Run
  • Or right-click the Output Channel and then click Stop Code Run in the context menu

Hurray, you just successfully set up your C++ environment in VsCode!

Here's a quick hint: By default, VsCode's output terminal is read-only. If you're running code that requires user input like:

How To Use Dev C++ Compiler

you won't be able to type into the terminal, Cannot edit in read-only terminal.
To fix this, you need to manually enable read-write.

  • In VsCode, Go to File > Preference > Setting.
  • In the User tab on the left panel, find the extensions section
  • Scroll and find 'Run Code Configuration'
  • Scroll and find a checkbox Run in Terminal (Whether to run code in Integrated Terminal) Check the box.

How To Compile C Files

Dev-C++ is a free IDE for Windows that uses either MinGW or TDM-GCC as underlying compiler.
Originally released by Bloodshed Software, but abandoned in 2006, it has recently been forked by Orwell, including a choice of more recent compilers. It can be downloaded from:
http://orwelldevcpp.blogspot.com

Installation

Run the downloaded executable file, and follow its instructions. The default options are fine.

Support for C++11

By default, support for the most recent version of C++ is not enabled. It shall be explicitly enabled by going to:
Tools -> Compiler Options
Here, select the 'Settings' tab, and within it, the 'Code Generation' tab. There, in 'Language standard (-std)' select 'ISO C++ 11':
Ok that. You are now ready to compile C++11!

Compiling console applications

To compile and run simple console applications such as those used as examples in these tutorials it is enough with opening the file with Dev-C++ and hit F11.
As an example, try:
File -> New -> Source File (or Ctrl+N)
There, write the following:
Then:
File -> Save As.. (or Ctrl+Alt+S)
And save it with some file name with a .cpp extension, such as example.cpp.
Now, hitting F11 should compile and run the program.
If you get an error on the type of x, the compiler does not understand the new meaning given to auto since C++11. Please, make sure you downloaded the latest version as linked above, and that you enabled the compiler options to compile C++11 as described above.
