A comprehensive guide to setting up the D programming language development environment, including installation of compilers, IDE configuration, and project management with DUB and Makefiles.
Setting up a robust development environment is crucial for any software engineer or architect looking to leverage the D programming language for advanced systems programming. This guide will walk you through the process of installing necessary compilers, configuring integrated development environments (IDEs), and managing projects with build tools like DUB and Makefiles. By the end of this guide, you’ll have a fully functional D development environment ready for building high-performance, scalable, and maintainable software systems.
The D programming language offers several compilers, each with its own strengths. The three primary compilers are DMD, LDC, and GDC. Let’s explore how to set up each of these compilers.
DMD is the reference compiler for the D programming language, known for its fast compilation times and ease of use. It is ideal for development and testing.
Download and Install DMD:
Verify Installation:
dmd --version to ensure DMD is installed correctly.1$ dmd --version
2DMD64 D Compiler v2.098.0
LDC is a D compiler based on the LLVM backend, offering excellent optimization capabilities and cross-platform support.
Download and Install LDC:
Verify Installation:
ldc2 --version to ensure LDC is installed correctly.1$ ldc2 --version
2LDC - the LLVM D compiler (1.28.0)
GDC is a D compiler that integrates with the GCC toolchain, providing compatibility with a wide range of platforms.
Install GDC:
1sudo apt-get install gdc
Verify Installation:
gdc --version to ensure GDC is installed correctly.1$ gdc --version
2gdc (GCC) 10.2.0
A good IDE can significantly enhance your productivity by providing features like syntax highlighting, code completion, and debugging tools. Here, we’ll cover configuring popular IDEs and editors for D programming.
Visual Studio Code (VS Code) is a popular, lightweight editor with excellent support for D through extensions.
Install Visual Studio Code:
Install D Language Support:
Ctrl+Shift+X).code-d extension.Configure DMD, LDC, or GDC:
Ctrl+Shift+P) and type D: Configure workspace.Sublime Text is another popular editor known for its speed and simplicity.
Install Sublime Text:
Install D Language Support:
D Language package via Package Control.Configure Build System:
Tools > Build System > New Build System.1{
2 "cmd": ["dmd", "$file"],
3 "file_regex": "^(...*?):([0-9]*):?([0-9]*)",
4 "selector": "source.d"
5}
IntelliJ IDEA offers robust support for D through plugins.
Install IntelliJ IDEA:
Install D Language Plugin:
File > Settings > Plugins.Configure Project SDK:
File > Project Structure > SDKs.Managing projects effectively is essential for any software development process. DUB and Makefiles are two popular tools for managing D projects.
DUB is the official package and build manager for D, simplifying dependency management and project configuration.
dub --version in the terminal.1$ dub --version
2DUB version 1.24.0
Create a New Project:
1dub init myproject
Build and Run the Project:
1dub build
2dub run
Makefiles provide a flexible way to manage complex build processes, especially for larger projects.
Makefile.1all: main
2
3main: main.d
4 dmd main.d -ofmain
make in the terminal to build the project.1$ make
2dmd main.d -ofmain
1clean:
2 rm -f main
Now that you have your D development environment set up, try creating a simple “Hello, World!” program to test your setup.
Create a New File:
hello.d.Write the Code:
1import std.stdio;
2
3void main() {
4 writeln("Hello, World!");
5}
1$ dmd hello.d
2$ ./hello
3Hello, World!
To better understand the setup process, let’s visualize the workflow using a flowchart.

Remember, setting up your development environment is just the beginning. As you progress, you’ll explore more complex projects and leverage the power of D to its fullest. Keep experimenting, stay curious, and enjoy the journey!
