Mar 15, 2010 In this article, let us discuss how to debug a c program using gdb debugger in 6 simple steps. Write a sample C program with errors for debugging purpose To learn C program debugging, let us create the following C program that calculates. How to use a debugger in DEV C? I am finding problems resolving run-time errors in my C code written in DEV C. How can the debugger help me resolve the run-time errors?
Once you have created a Linux C++ project in Visual Studio and you have connected to the project using the Linux Connection Manager, you can run and debug the project. You compile, execute, and debug the code on the remote target.
Visual Studio 2019 version 16.1 You can target different Linux systems for debugging and building. For example, you can cross-compile on x64 and deploy to an ARM device when targeting IoT scenarios. For more information, see Specify different machines for building and debugging later in this article.
There are several ways to interact with and debug your Linux project.
Debug using traditional Visual Studio features, such as breakpoints, watch windows, and hovering over a variable. Using these methods, you may debug as you normally would for other project types.
View output from the target computer in the Linux Console window. You can also use the console to send input to the target computer.
Debug your Linux project
Select debugging mode in the Debugging property page.
GDB is used to debug applications running on Linux. When debugging on a remote system (not WSL) GDB can run in two different modes, which can be selected from the Debugging Mode option in the project's Debugging property page:
GDB is used to debug applications running on Linux. GDB can run in two different modes, which can be selected from the Debugging Mode option in the project's Debugging property page:
In gdbserver mode, GDB is run locally, which connects to gdbserver on the remote system. Note that this is the only mode that the Linux Console window supports.
In gdb mode, the Visual Studio debugger drives GDB on the remote system. This is a better option if the local version of GDB is not compatible with the version installed on the target computer. |
Note
If you are unable to hit breakpoints in gdbserver debugging mode, try gdb mode. gdb must first be installed on the remote target.
Select the remote target using the standard Debug toolbar in Visual Studio.
When the remote target is available, you will see it listed by either name or IP address.
If you have not yet connected to the remote target, you will see an instruction to use Linux Connection Manager to connect to the remote target.
Set a breakpoint by clicking in the left gutter of some code that you know will execute.
A red dot appears on the line of code where you set the breakpoint.
Press F5 (or Debug > Start Debugging) to start debugging.
When you start debugging, the application is compiled on the remote target before it starts. Any compilation errors will appear in the Error List window.
If there are no errors, the app will start and the debugger will pause at the breakpoint.
Now, you can interact with the application in its current state, view variables, and step through code by pressing command keys such as F10 or F11.
If you want to use the Linux Console to interact with your app, select Debug > Linux Console.
This console will display any console output from the target computer as well as take input and send it to the target computer.
Configure other debugging options (MSBuild-based projects)
Command-line arguments can be passed to the executable using the Program Arguments item in the project's Debugging property page.
Specific debugger options can be passed to GDB using the Additional Debugger Commands entry. For example, you might want to ignore SIGILL (illegal instruction) signals. You could use the handle command to achieve this by adding the following to the Additional Debugger Commands entry as shown above:
handle SIGILL nostop noprint
Configure other debugging options (CMake projects)
You can specify additional command-line arguments for a CMake project in the launch.vs.json file. For more information, see Debug the CMake project
Debug with Attach to Process
Debug In Dev C++
The Debugging property page for Visual Studio projects, and the Launch.vs.json settings for CMake projects, have settings that enable you to attach to a running process. If you require additional control beyond what is provided in those settings, you can place a file named Microsoft.MIEngine.Options.xml in the root of your solution or workspace. Here is a simple example:
The AttachOptionsForConnection has most of the attributes you might need. The example above shows how to specify a location to search for additional .so libraries. The child element ServerOptions enables attaching to the remote process with gdbserver instead. To do that you need to specify a local gdb client (the one shipped in Visual Studio 2017 is shown above) and a local copy of the binary with symbols. The SetupCommands element enables you to pass commands directly to gdb. You can find all the options available in the LaunchOptions.xsd schema on GitHub.

Specify different machines for building and debugging
In Visual Studio 2019 version 16.1 You can separate your remote build machine from your remote debug machine for both MSBuild-based Linux projects and CMake projects that target a remote Linux machine. For example, you can now cross-compile on x64 and deploy to an ARM device when targeting IoT scenarios.

How To Debug Using Dev C ++ Online
By default, the remote debug machine is the same as the remote build machine (Configuration Properties > General > Remote Build Machine). To specify a new remote debug machine, right-click on the project in Solution Explorer and go to Configuration Properties > Debugging > Remote Debug Machine.
The drop-down menu for Remote Debug Machine is populated with all established remote connections. To add a new remote connection, navigate to Tools > Options > Cross Platform > Connection Manager or search for 'Connection Manager' in Quick Launch. You can also specify a new remote deploy directory in the project’s Property Pages (Configuration Properties > General > Remote Deploy Directory).
By default, only the files necessary for the process to debug will be deployed to the remote debug machine. You can use Solution Explorer to configure which source files will be deployed to the remote debug machine. When you click on a source file, you will see a preview of its File Properties directly below the Solution Explorer.
The Content property specifies whether the file will be deployed to the remote debug machine. You can disable deployment entirely by navigating to Property Pages > Configuration Manager and unchecking Deploy for the desired configuration.
Dev C Debug Tutorial
In some cases, you may require more control over your project’s deployment. For example, some files that you want to deploy might be outside of your solution or you want to customize your remote deploy directory per file ordirectory. In these cases, append the following code block(s) to your .vcxproj file and replace 'example.cpp' with the actual file names:
CMake projects
For CMake projects that target a remote Linux machine, you can specify a new remote debug machine in launch.vs.json. By default, the value of 'remoteMachineName' is synchronized with the 'remoteMachineName' property in CMakeSettings.json, which corresponds to your remote build machine. These properties no longer need to match, and the value of 'remoteMachineName' in launch.vs.json will dictate which remote machine is used for deploy and debug.
How To Debug C Code
IntelliSense will suggest all a list of all established remote connections. You can add a new remote connection by navigating to Tools > Options > Cross Platform > Connection Manager or searching for 'Connection Manager' in Quick Launch.
If you want complete control over your deployment, you can append the following code block(s) to the launch.vs.json file. Remember to replace the placeholder values with real values:

Dev C Debug Nasıl Yapılır
Dev C++ Debugger
I recently managed how to get debugging to work in Dev-C++, but I noticed 2 problems:
1. I have to manually enable 'create debug info' in the linker settings for debugging. Perhaps it should be enabled automatically (or by asking the user) when the 'debug'-button is pressed the first time.
2. If I set breakpoints, only the ones in my 'int main'-
function are reagrded and processed, but if I set them for example in the constructor of some of my classes the program never stops there. Also Dev-C++ says 'the .exe file is older than the source-files, do you want to recompile it?', even if I make a full recompile and then change nothing.
If somebody has an idea how to fix #2, it would be very cool, since I need debugging very much (as a beginner :) )
