Как установить gdb на windows

In this blog we will see how we can:

• Install updated version of C/C++ Compiler using MSYS2
• Install Debugger
• Install Visual Studio Code (VSC) IDE
• Integrate GCC compiler and debugger with Visual Studio Code (VSC)

All steps are shown in this YouTube video.

The GCC Compiler and MinGW:

The C and C++ compiler is the GCC Compiler. To install GCC, we can install MinGW. MinGW stands for Minimalist GNU for Windows. It’s a free and open-source software development environment specifically designed to create native Microsoft Windows applications.

So, we will install MinGW that has the GCC compiler as part of it. We can install MinGW directly from the website but we will install this using MSYS2. MSYS2 is a software installation and building platform for Windows.

Why to use MSYS2 to install MinGW?

In simple words it makes the installation process simple and handles the dependencies and updates with no effort. It uses the package manager named as pacman.

• MSYS2 uses Pacman, a powerful package manager, to install MinGW and its dependencies effortlessly
• MSYS2 handles dependencies automatically, ensuring that all required packages are installed correctly.

To install MSYS2, go to this link:

https://www.msys2.org/

• Under the “Installation” section, click the Installer to download that.
• Follow the steps for the installation process.
• It will be installed in C drive C:\msys64

MSYS2 provides a command-based interface. When you run the installed program it will open the command window something like this:

The first command will be using pacman to update the System. This will update system’s package database and upgrade all out-of-date packages. Use this command:

$ pacman -Syu

It will ask for yes or no as [Y/n], then press Y.

Now to install MinGW for 64 Bit system, use this command:

$ pacman -S mingw-w64-x86_64-gcc

It will ask for yes or no as [Y/n], then press Y.

After this step MinGW will be installed. If there is any error at the end, you may need to repeat the process.

Verify if MinGW and GCC Compiler has been installed:

First exit from the MSYS2 command window. For that, simply use the Exit command to exit from MSYS2 as:

$ exit

Now from the Windows start menu, search for MSYS2 MinGW 64. If you find that it means MinGW has been installed. Click that to open the MSYS2 command window again. We can verify if GCC compiler is installed successfully. For that, use the command:

$ gcc –version

And we should get the information about GCC with version number

Installation of GDB Debugger:

While coding in C and C++ we should also install the debugger which is a powerful tool to find and fix errors in the code. We will install GDB which stands for GNU Debugger.

For that, we will use this command in MSYS2 command window:

$ pacman -S mingw-w64-x86_64-gdb

It will ask for yes or no as [Y/n], then press Y.

To verify if the debugger has been installed successfully, use the following command:

$ gdb –version

You must see the version information in the output. Everything has been installed and we can simply exit the MSYS2 using the exit command.

Setting up Windows System Variables:

There is one last crucial step before we can start writing code, and that is making the GCC compiler accessible throughout your system. This means you can use the GCC compiler from any directory without specifying its full path. For that we need to open the command prompt of windows by going to Windows Search bar and typing CMD. It will open the command prompt as:

To verify if GCC is accessible here, write the command

> gcc –version

Most probably you will get the error like:

‘gcc’ is not recognized as an internal or external command,

The reason is that MSYS2 was installed in the Drive C. Locate that folder:

Картинка с сайта: learningorbis.com

Inside msys64 folder, we have the folder for mingw64 –> bin  and inside bin folder we have all exe applications like gcc and gdb. So we need to tell the Windows about this path so that when we will run the codes, it knows where to find the compiler GCC. Copy the path: C:\msys64\mingw64\bin.

Now go to Windows Search bar and search for “Environment Variables” and click “Edit the system environment variables”. This window will open:

Картинка с сайта: learningorbis.com

Click “Environment Variables” at the bottom of the above window. A new window will open and we need to edit the path variable in the lower section:

Картинка с сайта: learningorbis.com

Select the Path variable and Click “Edit” to edit it. This window will open:

Картинка с сайта: learningorbis.com

Here click “New” to add a new path and paste the path C:\msys64\mingw64\bin. Then Click “OK” a couple of times.

Now you can open the command prompt again (using CMD in Windows search bar) and verify the installation of GCC and GDB with these commands:

> gcc –version

And

>> gdb –version

And this time instead of error you should get the version information.

C/C++ compiler and debugger has been installed.

Installation of Visual Studio Code and integrating GCC:

For the better and professional experience we can install the IDE “Visual Studio Code” and configure it for C and C++. This offers a rich set of features for code editing, debugging, IntelliSense, and project management, significantly enhancing productivity and code quality.

Let’s see how we can install and configure Visual Studio Code.

Go to this link: https://code.visualstudio.com/ And click “Download for Windows”

Choose the operating system as Windows 10 and 11 and installer download will start. Run the installer and follow the steps to install Visual Studio Code.

To install C/C++ support, go to Extension and then search for C/C++. And install the first extension you see.

Картинка с сайта: learningorbis.com

You should also install another extension “Code Runner” which offers a bunch of useful features. The detail is provided in THISSSSSSSSSSSSSSSSSSSSS video.

Test C and C++ Codes:

To finally verify the execution of C and C++ programs, open some directory in Visual Studio Code, where you want to save the coding files. Create a new file for the C program and use the extension C (e.g. test.c). Test this simple Hello World program:

#include <stdio.h>

int main() {

printf(“Hello, World!\n”);

return 0;

}

You should see the output as the text Hello World.

Test another program that takes user’s input:

#include <stdio.h>

int main() {

int num;

// Prompt the user for input

printf(“Enter an integer: “);

// Read the integer input from the user

scanf(“%d”, &num);

// Calculate the square of the input number

int square = num * num;

// Print the result

printf(“The square of %d is %d\n”, num, square);

return 0;

}

You might face a problem taking input from the user. The solution is running the code in the terminal and that’s where the extension “Code Runner” we installed will help us. For that go to settings and search for “Code Runner”. Then search for the setting “Run in Terminal” and click the checkbox. Now the above code that takes input a number from the user should work correctly.

The last thing we will see is running a C++ code. No setting or configuration needs to be changed. You just need to use the extension .cpp instead of .c for the file. You can test this sample C++ program:

#include <iostream>

int main() {

int num;

// Prompt the user for input

std::cout << “Enter an integer: “;

// Read the integer input from the user

std::cin >> num;

// Calculate the square of the input number

int square = num * num;

// Print the result

std::cout << “The square of ” << num << ” is ” << square << std::endl;

return 0;

}

WINDOWS

For developers transitioning to or working in a Windows environment, setting up a robust toolchain for C and C++ programming is crucial. The GNU Compiler Collection (GCC) and the GNU Debugger (GDB) are two essential tools for compiling and debugging applications at a low level. This guide will walk you through the steps of installing GCC and GDB using MSYS2, a software distribution and building platform for Windows.

What is MSYS2?

MSYS2 stands for “Minimal SYStem 2” and is a modern and actively maintained fork of the original MSYS. It provides a Unix-like environment on Windows, making it possible to run common Linux tools and applications. It also comes with a package manager called pacman, allowing easy installation of development tools like GCC and GDB.

Prerequisites

Before you begin the installation of GCC and GDB on Windows through MSYS2, ensure that you have the following:

• Windows Operating System: MSYS2 supports Windows 7 and above.

• Basic Command Line Knowledge: Familiarity with the command line interface is helpful.

• Administrator Access: You may need admin rights to install MSYS2 and its components.

Step-by-Step Installation Guide

Step 1: Download MSYS2

1. Go to the MSYS2 website.

2. Click on the download link for the latest installer (usually named something like msys2-x86_64-YYYYMMDD.exe).

3. Run the installer and follow the prompts to install MSYS2 in your preferred directory (the default is usually C:\msys64).

Step 2: Update Packages

After installation, you’ll need to update your package database and core system packages:

1. Open the MSYS2 shell from the Start menu.

2. Run the following commands in the terminal:

• This command will synchronize the package database and update the core system packages. If prompted to close the terminal and restart, follow the instructions.

1. After restarting, run the update command again to ensure everything is up-to-date:

Step 3: Install GCC and GDB

With MSYS2 updated, you can now install GCC and GDB:

1. In the same MSYS2 shell, use the following command to install GCC:

   pacman -S mingw-w64-x86_64-gcc

• This command installs the GCC compiler for 64-bit Windows.

1. Next, install GDB with the following command:

   pacman -S mingw-w64-x86_64-gdb

Step 4: Set Up Environment Variables

To ensure you can easily use GCC and GDB from anywhere in the command line, you need to add MSYS2’s mingw64/bin directory to your system’s PATH.

1. Right-click on ‘This PC’ or ‘Computer’ on your desktop or file explorer.

2. Select ‘Properties’.

3. Click on ‘Advanced system settings’.

4. In the System Properties window, click on the ‘Environment Variables’ button.

5. In the ‘System variables’ section, find the Path variable and select it, then click on ‘Edit’.

6. Add the following path to the list (adjust if installed in a different location):

1. Click OK to close all dialog windows and save your changes.

Step 5: Verify Installation

To confirm that GCC and GDB are installed correctly, you can run the following commands in the MSYS2 terminal or in a new Command Prompt window:

gcc --version
gdb --version

You should see output displaying the versions of GCC and GDB installed on your system.

Basic Usage

Compiling a C Program

Here’s a simple example of compiling and debugging a C program using GCC and GDB:

1. Create a new C file, for example hello.c, with the following content:

   #include <stdio.h>

   int main() {
       printf("Hello, World!\n");
       return 0;
   }

1. Compile the program using GCC:

• The -g flag includes debugging information which is useful when using GDB.

1. Now, run GDB to debug your program:

1. Once in GDB, you can run the program by typing:

1. To set breakpoints and debug, you can use commands like:

   break main      # Set a breakpoint at the main function
   continue        # Continue execution until the next breakpoint

Conclusion

Setting up GCC and GDB on Windows using MSYS2 is a straightforward process that can significantly enhance your development capabilities for C and C++ programming. With the Unix-like environment provided by MSYS2 and the power of the GNU toolchain, you can compile, debug, and build applications seamlessly on Windows.

For further reading and additional resources, consider checking out the MSYS2 documentation and the GCC documentation.

Happy coding!

GDB is the GNU Debugger. It can be used to get information about crashes, including backtraces, which can be very helpful to the programmers when you report bugs.

getting a debug build of the OHRRPGCE[edit]

The latest debug build of the OHRRPGCE is available here: ohrrpgce-wip-directx-sdl-debug.zip. When used together with gdb, it can provide useful information about crashes.

Installing gdb[edit]

If you are using Linux, you probably already have gdb, but if you are using Windows, you will need to install it.

MinGW distributes a Windows version of gdb. You can get the latest mingw installer here which can in turn install gdb.
After installing MinGW, run the «MinGW Installation Manager» (which for me was located in C:\MinGW\libexec\mingw-get\guimain.exe ) and then make sure that the mingw32-gdb bin package is installed.
(These instructions are for mingw32, not the mingw-w64 fork. But gdb from mingw-w64 should work too.)

Starting gdb[edit]

gdb will not show up in your start menu. It is a command-line program. From a command-line prompt, you can type:

c:\mingw\bin\gdb.exe program_to_debug.exe

Or you can create a batch file with the same command in it. There is already a pair of pre-made batch files for debugging the OHRRPGCE.

C:\OHRRPGCE\gdbgame.bat

C:\OHRRPGCE\gdbcustom.bat
