Hi,
While gdb is working fine in terminal [even the one inside visual code], and is able to attach to the running process fine, with the command 'gdb ./demo 10113' [gdb ].
It is not able to attach in visual code.

I am using the below config in launch.json ->

{
"name": "(gdb) Attach",
"type": "cppdbg",
"request": "attach",
"program": "/home/oswald/lab/repos/oswald_FNP_main/FNP/_output/_debug/11.19.8.0/main/Linux-x86_64-ipv6/x64_linux/demo",
"processId": "12657",
"MIMode": "gdb",
"miDebuggerPath": "/usr/bin/gdb", // Path to GDB
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
},
{
"description": "Set Disassembly Flavor to Intel",
"text": "-gdb-set disassembly-flavor intel",
"ignoreFailures": true
}
],
"logging": {
"engineLogging": true,
"trace": true,
"traceResponse": true
}
}

It is starting and then closing, with not logs in the Debug console.

I am using centos7, and beside this, VS Code is running fine, and on its own gdb is also working fine.

I may be going wrong somewhere, but I tried to dig in, and found nothing.

Help will be really appreciated.
Thanks and regards,
Amit Kr Das.
