GCC (from Homebrew) build Error: as: unrecognized option '--gdwarf-5'

Question

I'm a new to C++ and I'm using VSCode for the IDE.The system I use is WSL. I installed the GCC(11 and 12) from Homebrew in the wsl system. After I configured task and tried to run the task, I got the error of as: unrecognized option '--gdwarf-5'. The task.json is:

            "type": "cppbuild",
            "label": "Build with GCC 11.3.0",
            "command": "/home/linuxbrew/.linuxbrew/bin/g++-11",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": "build",
            "detail": "compiler: /home/linuxbrew/.linuxbrew/bin/g++-11"
        }

As you can see there's a "-g" in the args, while the compiler is from homebrew. It will give me the error as: unrecognized option '--gdwarf-5'. But when I delete the argument "-g", it will build successfully.

However, when I use the GCC 9 which is not installed by hombrew, the task.json is :

{
            "type": "cppbuild",
            "label": "Build with GCC 9.4.0",
            "command": "/bin/g++",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": "build",
            "detail": "compiler: /bin/g++"
        }

As you can see there's also a "-g" in the arges, while the compiler is not from homebrew. And there's no error when building with the "-g"

It's super confusing for me, I guess it could because of the GCC path? But in the tutorial I am watching it is totally fine with the "-g" using the GCC 11 from Homebrew.

(And I have another question, Why VScode can't find the GCC 12 I installed from Homebrew? )

Thank you for any help!

Weren't all these fancy GUI IDEs and editors, like VSCode, with their pretty dialogs and buttons, supposed to make things easier, to avoid all these yucky `Makefile`s and command lines? You mean that you have to invoke some magic incantation in the form of a convoluted JSON configuration file, to get basic functionality right? That's a darn shame, isn't it? After reading `make`s man page, as lengthy as it is, with plenty of examples, it's always pretty straightofrward for me to simply push `F5` in emacs, and get everything built. — Sam Varshavchik, Oct 09 '22 at 13:55
@SamVarshavchik • lol, that's the dream. The dream falls a bit short of the reality. — Eljay, Oct 09 '22 at 14:12
Please don't post images of text (code). Post actual *text* instead. — Jesper Juhl, Oct 09 '22 at 15:51
@SamVarshavchik I wouldn’t call vs code an IDE, personally, nothing is integrated about it at all. Everything is bolt-on. — Taekahn, Oct 09 '22 at 18:11
@Taekahn I'll take everything-bolted-on over everything-(jb)welded-on-and-painted-over-to-hide-the-evidence any day of the week. — n. m. could be an AI, Oct 09 '22 at 21:58
@n.1.8e9-where's-my-sharem. Ok….? It wasn’t some sort of judgement call or me trying to promote _the one true IDE_ . I actually like the minimalist approach. People should use whatever development environment they prefer. I just don’t think we should get into the habit of calling everything used to write code an IDE. While there is no absolute definition of the word, I personally believe that an ide should provide a full development environment out of the box. — Taekahn, Oct 09 '22 at 22:32
@Jesper Juhl Thank you for reminding me, images are replaced by the real codes. — Adam Qi, Oct 10 '22 at 06:56
@ssbssa Thanks. It could be a similar question. I tried to update the Binutils but my Binutils version is already up-to-date (version: 2.39_1), anything I could do other than that? (Also tried reinstall the Binutils, doesn't work) — Adam Qi, Oct 10 '22 at 13:14
But do you maybe still have an older binutils version around which gcc is using? — ssbssa, Oct 10 '22 at 13:32
@SamVarshavchik there are better build systems than "make" (I'm using AdaCore gprbuild for C/C++ and Ada), but I admit I never got VS code to work properly. Yes, they moved the problem from well-known makefiles to another microsoft convoluted thingy. I don't believe in editors that can handle all languages & compilers either. Too generic means lots of configuration and lots of possible errors — Jean-François Fabre, Nov 17 '22 at 22:55
