使用gcc，g ++和gdb在Window 7上设置VSCode进行C / C ++调试 [英] Setting up VSCode for C/C++ debugging on Window 7 with gcc, g++ and gdb

问题描述

我遵循此处的指示。安装了cpptools。创建 tasks.json 以下内容：

  {
 version：0.1.0，
command：g ++，
isShellCommand：true，
showOutput：always，
args ：[-g，helloworld.c] 
} 
  

launch.json 以下内容：

  {
版本：0.2.0，
配置：[
 
 {
name：C ++ Launch（Windows），
type： cppvsdbg，
request：launch，
program：$ {workspaceRoot} /a.exe，
args：[]，
 stopAtEntry：false，
cwd：$ {workspaceRoot}，
environment：[]，
externalConsole：false，
windows： {
MIMode：gdb，
miDebuggerPath：C：\\ Mahesh\\Program Files\\\\\\\\\\\\\\\\\ MinGW \\\\\\\\\\\\\\\\\\\\\\\\'\\\\\\\\\\\\\\\' 
program：$ {workspaceRoot} /a.exe，
type：cppvsdbg，
request：attach，
processId ：$ {command.pickProcess}，
windows：{
MIMode：gdb，
miDebuggerPath：C：\\Mahesh\\\ \\程序文件\\\\\\\\\\\\\\\\\\\\\\\\\\\\\  

当我执行 Ctrl + Shift + B 时， ，生成 a.exe 。当我运行调试时，它会提供以下输出：

线程9524已退出，代码为0（0x0）。 
 Hello World !!! 
程序'[7876] a.exe'已经用代码0（0x0）退出。 
  

但是代码没有达到我在代码中设置的调试点。你可以看到，它正在打印Hello World !!!。如何配置，以便它能让我在调试时逐步完成代码？

环境：

• 程序'[7876] a.exe'已退出，代码为0（0x0），
  为i686-pc-mingw32。


• gcc.exe（x86_64-win32-seh-rev201506，mingwpy build）4.9.2


• g ++ .exe（x86_64-win32-seh-rev201506，mingwpy build） li>
  

更新

• 在评论的讨论中，我被要求使用 m32 标志，因为我的编译器是64位的，它可能会生成64位二进制文​​件。但是 gcc -m32 helloworld.c 给出了诸如这的错误。 此处评论用 -m32 选项解释它。它要求在编译时添加 i686-w64-mingw32 / x86_64-w64-mingw32 标志。但是 gcc -x86_64-w64-mingw32 helloworld.c 给出语言无法识别错误， gcc -i686-w64-mingw32 helloworld.c 给出无法识别的命令行选项。我做错了什么？


• 还这篇文章说，调试目前只能用于Linux，而不能用于Windows。是这样吗？如果你想让command.PickProcess工作。

它应该是'：'不是'。' - 因此：



  {
name：.NET Core Attach，
type：coreclr，
request：attach，
processId： $ {command：pickProcess}

  

应该把你排序：）




I was following instructions from here. Installed cpptools. Created tasks.json with following contents:

{
    "version": "0.1.0",
    "command": "g++",
    "isShellCommand": true,
    "showOutput": "always",
    "args": ["-g", "helloworld.c"]
}

And launch.json with following content:

{
    "version": "0.2.0",
    "configurations": [

        {
            "name": "C++ Launch (Windows)",
            "type": "cppvsdbg",
            "request": "launch",
            "program": "${workspaceRoot}/a.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceRoot}",
            "environment": [],
            "externalConsole": false,
            "windows": {
                "MIMode" : "gdb",
                "miDebuggerPath": "C:\\Mahesh\\Program Files\\mingw\\MinGW\\bin\\gdb.exe"
            }

        },
        {
            "name": "C++ Attach (Windows)",
            "program": "${workspaceRoot}/a.exe",
            "type": "cppvsdbg",
            "request": "attach",
            "processId": "${command.pickProcess}",
            "windows": {
                "MIMode" : "gdb",
                "miDebuggerPath": "C:\\Mahesh\\Program Files\\mingw\\MinGW\\bin\\gdb.exe"
            }
        }
    ]
}

When I do Ctrl+Shift+B, the code builds, generating a.exe. When I run debug, it gives following output:

The thread 9524 has exited with code 0 (0x0).
Hello World!!!
The program '[7876] a.exe' has exited with code 0 (0x0).

But the code is not hitting the debug point I set up in the code. You can see, it is printing "Hello World!!!". How can I configure so that it will allow me to step through the code while debugging?

Environment:

• The program '[7876] a.exe' has exited with code 0 (0x0), configured as "i686-pc-mingw32".
• gcc.exe (x86_64-win32-seh-rev201506, mingwpy build) 4.9.2
• g++.exe (x86_64-win32-seh-rev201506, mingwpy build) 4.9.2

Update

• In the discussion in the comments, I have been asked to run gcc with m32 flag as my compiler is 64-bit, it may be generating 64-bit binaries. But gcc -m32 helloworld.c gave errors like this. The comment here explains it with -m32 option. It asks to add i686-w64-mingw32/x86_64-w64-mingw32 flags while compiling. But gcc -x86_64-w64-mingw32 helloworld.c gives language not recognized error, gcc -i686-w64-mingw32 helloworld.c gives unrecognized command line option. What I am doing wrong?
• Also this article says that debugging is currently possible only with linux but not with Windows. Is it so?

解决方案

If you want command.PickProcess to work..

It should be a ':' not a '.' - therefore:

{
    "name": ".NET Core Attach",
    "type": "coreclr",
    "request": "attach",
    "processId": "${command:pickProcess}"
}

Should sort you out :)
