vscode不能命中断点如何解决？

vscode c++ 编译生成后,调试时无法命中断点的解决办法

//test.cpp#include <stdio.h>int g_var = 0;void print_line(char *str){    if (str != NULL)        printf("%s\r\n", str);    else        printf("null string\r\n");}int main (int argc, char **argv){    int l_var = 1;    print_line("hello world!");    printf("g_var = %d, l_var = %d.\r\n", g_var, l_var);    return 0;}

launch.json

{        "version": "0.2.0",        "configurations": [{    "name": "(gdb) Launch",    "type": "cppdbg",    "request": "launch",    "program": "${workspaceRoot}/test.exe",    "args": [],    "stopAtEntry": false,    "cwd": "${workspaceRoot}",    "environment": [],    "externalConsole": true,    "MIMode": "gdb",    "miDebuggerPath": "C:\\MinGW\\bin\\gdb.exe",    "setupCommands": [        {"description": "Enable pretty-printing for gdb","text": "-enable-pretty-printing","ignoreFailures": true        }    ]}        ]    }

tasks.json

{    // See https://go.microsoft.com/fwlink/?LinkId=733558    // for the documentation about the tasks.json format    "version": "2.0.0",    "tasks": [        {"taskName": "test","type": "shell","command": "g++","args": ["-g", "${file}", "-o", "${workspaceRoot}/test.exe"]        }    ]}

编译成功后，在源码中设置断点，却无法命中断点。

后来查看官方c++编译调试文档和尝试，在launch.json文件的

"setupCommands": [{"description": "Enable pretty-printing for gdb","text": "-enable-pretty-printing","ignoreFailures": true}]

后面加上

"preLaunchTask": "test" 配置，调试时就可以正常命中断点了。

注意：别忘了"setupCommands"的中括号’ ] ‘后面加上一个逗号。
