Building Linux GUI Applications with WSL using GCC/Clang
In this article, we will explore how to build Linux GUI applications using the Windows Subsystem for Linux (WSL) and the GCC/Clang compilers. We will cover the basics of setting up your development environment and building a simple GUI application using the GTK+ library.
Setting up your development environment
To get started, you will need to install the Windows Subsystem for Linux on your Windows machine. This will allow you to run a full Linux environment alongside your Windows system. Once you have WSL installed, you can choose a Linux distribution to use, such as Ubuntu or Debian.
Next, you will need to install the GCC or Clang compiler. GCC is the default compiler on most Linux distributions, but you can also install Clang if you prefer. To install GCC, use the following command:
sudo apt-get install gcc
Or, to install Clang, use the following command:
sudo apt-get install clang
You will also need to install the GTK+ library, which is a popular library for building GUI applications in Linux. To install GTK+, use the following command:
sudo apt-get install libgtk-3-dev
Building a simple GUI application
Now that you have your development environment set up, let's build a simple GUI application using the GTK+ library. Here is an example of a simple GTK+ application that displays a window with a button:
#include <gtk/gtk.h>
int main(int argc, char *argv[]) {
gtk\_init(&argc, &argv);
GtkWidget *window = gtk\_window\_new(GTK\_WINDOW\_TOPLEVEL);
gtk\_window\_set\_title(GTK\_WINDOW(window), "My GUI Application");
gtk\_window\_set\_position(GTK\_WINDOW(window), GTK\_WIN\_POS\_CENTER);
GtkWidget *button = gtk\_button\_new\_with\_label("Click me!");
g\_signal\_connect(button, "clicked", G\_CALLBACK(gtk\_main\_quit), NULL);
GtkWidget *box = gtk\_box\_new(GTK\_ORIENTATION\_VERTICAL, 5);
gtk\_box\_pack\_start(GTK\_BOX(box), button, TRUE, TRUE, 0);
gtk\_container\_add(GTK\_CONTAINER(window), box);
gtk\_widget\_show\_all(window);
gtk\_main();
return 0;
}
To build this application, use the following command:
gcc my\_gui\_application.c -o my\_gui\_application `pkg-config --cflags --libs gtk+-3.0`
This command tells GCC to compile the my\_gui\_application.c file and link it with the GTK+ library. The pkg-config utility is used to automatically determine the necessary compiler flags and libraries for the GTK+ library.
Once the application is built, you can run it using the following command:
./my\_gui\_application
Running the WSL command prompt
Windows Subsystem for Linux (WSL) allows you to run a linux environment alongside your windows system. This means you can have multiple command prompt open and running different linux distributions. To open the WSL command prompt, you can use the following steps:
- Press the Windows key on your keyboard
- Type "Command Prompt" and select the "Command Prompt" app from the search results
- In the Command Prompt window, type "wsl" and press Enter
- This will open a new command prompt window running your default linux distribution
