vscode不能命中斷點如何解決？

vscode c++ 編譯生成后,調試時無法命中斷點的解決辦法

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

編譯成功后，在源碼中設置斷點，卻無法命中斷點。

后來查看官方c++編譯調試文檔和嘗試，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，調試時就可以正常命中斷點了。

注意：別忘了"setupCommands"的中括號’ ] ‘后面加上一個逗號。
