}

解决终端出现 [1] + Done “/usr/bin/gdb” —interpreter=mi —tty=${DbgTerm} 0<”/tmp/Microsoft-MIEngine-In-wyyxzchw.1pu” 1>”/tmp/Microsoft-MIEngine-Out-qddpshqk.bcg”

在 launch.json 的 configuration 中添加：

1
"miDebuggerArgs": "-q -ex quit; wait() { fg >/dev/null; }; /usr/bin/gdb -q --interpreter=mi",

重新编译运行

最终，launch.json 内容为
