Here are the steps that I followed, if someone is still looking for an answer.
brew install gccgcc --version- cd to InstalledDir path:
cd /Library/Developer/CommandLineTools/usr/include
- create bits directory in there. use sudo if permission issues
sudo mkdir bits
- copy
stdc++.hlink in bits directory, in my case I downloaded it in Downloads.cd bitssudo cp ~/Downloads/stdc++.h stdc++.h
This was enough for the compiling.

How to Fix <bits/stdc++.h> File not Found in MacOS? - GeeksforGeeks
July 23, 2025 - The bits/stdc++.h is a GCC-specific header file and is not available by default on MacOS, which uses Clang. To fix the “file not found” error, you can create your own stdc++.h file and place it in a directory where Clang can find it.
c++ - How can I include <bits/stdc++> in Xcode - Stack Overflow
Go to the libraries location inside the include folder create a bits folder. Inside the bits folder create a stdc++.h file with these contents. Note if you face some error like a particular header file not found please comment those lines in stdc++.h. More on stackoverflow.com
Why so many students are using '#include<bits/stdc++.h>' instead of '#include<iostream>'?
IIRC that brings the whole C++ standard library as if you included every single header (iostream, algortihms, memory, map, vector, etc etc etc) by hand. The resulting binary would be the same but compile times will be longer. More on reddit.com

You can do it by copying stdc++.h file from here: https://gist.github.com/reza-ryte-club/97c39f35dab0c45a5d924dd9e50c445f
Then you can include the file in your c++ file like this:
//suppose the file is in your home folder, here my username is reza
#include "./stdc++.h"

Since, bits/stdc++ is a GNU GCC extension, whereas OSX uses the clang compiler.
You have to create bits directory inside /usr/local/include and then make a header file stdc++.h inside bits and paste the contents of this gist inside it. Then, it should compile as expected.
Since, /usr directory is hidden by default on Mac OSX.
- Open Finder.
- Click Go on menu bar then click Go to folder or Press Command+Shift+G directly.
- Enter the path /usr/local/include
- Now proceed as mentioned above.
(UPDATE: For latest OS X you need to make folder include inside local and make bits folder inside include folder and then copy paste the code inside bits folder.)

Because they are mostly folks who are coming in via competitive programming backgrounds and/or most of the C++ stuff they saw comes from websites like geeksforgeeks, where other competitive programmers write algorithm tutorials in C++ using patterns like this. I have said it once and I have said it before, if a candidate's exposure to C++ is only through competitive programming or leetcode, then their C++ experience is not to be taken seriously. They may know some things about the STL, their concepts like OO, templates, move semantics, memory management, concurrency, build systems, testing i.e stuff that actually matters in a production C++ environment, are seriously lacking or non-existent. I took a guess that you're from India, and well, looks like you are, this is very prevalent there.

Create a file named stdc++.h inside the bits folder and open it using any text editor (e.g. TextEdit) Paste the content from this repo to stdc++.h file: stdc++.h · Now close Sublime Text/VS Codeand reopen it and run a C++ file. It should work! Try the same thing using path = /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/ It should work now, but it might give you errors like include is not found or similar.

#include<bits/stdc++.h> is an internal header for the GCC and you are not supposed to use it, it's not portable.
remove the #include<bits/stdc++.h>
instead write #include<vector> and #include<iostream>
also remove using namespace std it considered bad practice
so you code should look like this:
#include <vector>
#include <iostream>
int main()
{
// Create an empty vector
std::vector<int> vect;
vect.push_back(10);
vect.push_back(20);
vect.push_back(30);
for (int x : vect)
std::cout << x << " ";
return 0;
}

I was having the same issue. First I installed gcc via homebrew
brew install gcc
To avoid conflict with the existing gcc (and g++) binaries, homebrew names the binary suffixed with version. At time of this comment, the latest was gcc-10.
You dont have to copy the bits/stdc++.h after this. Just compile using g++-<major-version-number> instead of g++, which would use the homebrew installed binary instead of the default osx one. For me it is
g++-10 -Wall -O2 -std=c++11 test.cpp -o test
To check the binary name that homebrew installed you can look in the /usr/local/bin directory because thats where homebrew installs packages.
Also, make sure that usr/local/bin is before /usr/bin in your $PATH

Also I recommend you MacVim for coding, it's way better than Xcode or Vscode for competitive programming. Xcode just takes a lot of space and for each cpp file it requieres a Project in order to compile, that's not comfortable (Months ago I also used to use Xcode).
