Apple - File Not Found Error while including bits/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 code inside it. Then, it should compile as expected.

Here are the steps that I followed, if someone is still looking for an answer.

• brew install gcc
• gcc --version
• cd to InstalledDir path:
  1. cd /Library/Developer/CommandLineTools/usr/bin
  2. cd ../include
• create bits directory in there. use sudo if permission issues
  1. sudo mkdir bits
• copy stdc++.h link in bits directory, in my case I downloaded it in Downloads.
  1. cd bits
  2. sudo cp ~/Downloads/stdc++.h stdc++.h

This was enough for the compiling.

The file is distributed with GCC. You install GCC with Macports or Homebrew.

brew install gcc
