How to debug remote gdb in vscode? The following article will introduce to you the method of remote gdb debugging of vscode. I hope it will be helpful to you!
Recently, with the guidance of a colleague, I tried using vscode for gdb debugging. After using it, it felt "really good".
Without further ado, what this article is going to achieve is: remote debugging the c code on the linux server and arm embedded device on the windows side, and sorting out the configuration and use of gdb debugging.
First you need to achieve remote connection to the server, search for "remote-ssh" in the plug-in library, double-click to download and install it (in the picture below I Already installed), after installation, the remote resource manager will appear in the sidebar.

Click the + sign and enter ssh in the pop-up command window to log in command, follow the prompts, enter the password and confirm, the connection will be successful
Create on the server A c code, here is the code in "Linux C Get System User Name" as an example, it is very simple
#include#include #include int main() { struct passwd* pwd; uid_t userid; userid = getuid(); pwd = getpwuid(userid); std::cout << "pw_name:" << pwd->pw_name << std::endl; std::cout << "pw_passwd:" << pwd->pw_passwd << std::endl; std::cout << "pw_uid:" << pwd->pw_uid << std::endl; std::cout << "pw_gid:" << pwd->pw_gid << std::endl; std::cout << "pw_gecos:" << pwd->pw_gecos << std::endl; std::cout << "pw_dir:" << pwd->pw_dir << std::endl; std::cout << "pw_shell:" << pwd->pw_shell << std::endl; return 0; }
The compilation method is as follows, be sure to add the -g command, otherwise Unable to debug with gdb
g++ -g test.cpp -o test
Then click File-Open Folder and find the created code path. After confirmation, you can see the code file in the resource manager on the left.
You need to install the c extension for the first run. In the extension page, install C/C
## Also search for GDB Debug and install it After installation, click the "Run and Debug" button, "Create launch.json" file, Select C (GDB /LLDB) item, automatically generate launch.json file, the content is as follows{ // 使用 IntelliSense 了解相关属性。 // 悬停以查看现有属性的描述。 // 欲了解更多信息,请访问: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [] }
