Include bits/stdc++.h on mac
bits/stdc++ is a GNU GCC extension, whereas OS X uses the clang compiler. However, you can install gcc and make it work by manually adding the header file.
- Install xcode command line tools using this command
xcode-select --install - Install Homebrew (if not installed)
- Instal gcc with this command:
brew install gcc - Now open terminal and navigate:
cd /usr/local/bin - Now link g++-10 to g++ using this command:
ln -s g++-10 g++ - Now log out and log back in
- Now copy stdc++.h file using this command:
cp ~/Path-to-file/stdc++.h /usr/local/Cellar/gcc/10.1.0/include/c++/10.1.0/bits(Exact path of the bits folder may change according to your installed gcc version/Mac OS version)
Now it should compile as expected
I have also included "using namespace std;" in this file. So, from now on you dont need to write it everytime you create a cpp file.
NB:
- If you are facing compile issue with gcc after installing then uninstall gcc and use this command to build gcc from source:
brew install --build-from-source gcc - I tested this version on Mac OS Catalina and gcc 10.1.0, if you are facing any issues then feel free to create an issue.
