C++: error: unexpected token in '.section' directive while compiling C++ code in macOS

Question

I've recently upgraded my Mac to macOS Ventura, and upgraded my g++ to g++-12 using homebrew.

But later I found I will get the error: unexpected token in '.section' directive while compiling in a code like this:

#include<vector>
#include<iostream>
using namespace std;
const int N=1e5+10;
vector<int> test[N];

int main(){
    puts("Hello");
    return 0;
}

Which is usually OK to compile.

I'm Using Vscode with the coderunner Ad-on.

I tried to reinstall my compiler and recompile my compiler. I think it may help, but actually not.

I've searched the internet but I found nothing to solve the problem, either in Stackoverflow. It seems that everyone else having the same problem are not using C++.

I tried to ask my teacher and schoolmates, but no one knows why.

So why is this happening? Thanks in advance.

Here's the full log and verbose output

Are you sure you want a `100010` empty vectors? Or do you want a single vector with `100010` elements? — Some programmer dude, Nov 18 '22 at 09:07
On a different note, your use of the *floating point* value `1e5+10`, mixing in the C function `puts` (for which you don't actually include the correct header file), possibly mixing array definitions and vector initialization, adding some extra elements to your array/vector, they all point to you learning programming from some kind of "competition" or "judge" site. Please note that such sites are *not* any kind of learning or teaching resources. They all assume that you already know programming and the selected language very well. — Some programmer dude, Nov 18 '22 at 09:17
@Someprogrammerdude Yes, I do want 100010 empty vectors. The vectors here were just used as an example to show when the problem will appear. I know the difference between vectors and arrays. — Sheng Horizon, Nov 18 '22 at 13:41
Can you please include the full and complete build log from this example in your question? Also please try to build with the `-v` flag to get verbose output from the compiler, which could give further information. — Some programmer dude, Nov 18 '22 at 13:52
@Someprogrammerdude OK /var/folders/46/gnq0_xf15dj0d3drfw04nz7c0000gn/T//ccGl2TIh.s:477:29: error: unexpected token in '.section' directive .section .data.rel.ro.local ^ — Sheng Horizon, Nov 18 '22 at 14:13
Please [edit] your question to include the full and complete build output (with verbose option turned on). — Some programmer dude, Nov 18 '22 at 14:15
To me it looks like a mismatch between the GCC compiler and its generated object files, and the Clang linker which doesn't quite recognize all the data in those object files. — Some programmer dude, Nov 21 '22 at 08:14
@Someprogrammerdude Thank you so much. Would you mind telling me what maybe I should do? — Sheng Horizon, Dec 28 '22 at 00:21

if you try with g++, add these options: -O2 -Wall -lm

just `-O2` is sufficient. – Dushyant Singh May 08 '23 at 18:53
