I was trying to figure out how to include bits/stdc++.h on macos since it uses clang, So once i found the solution i thought of creating a clear video about how to do it.

For me this only works in Xcode. It still doesn't compile in CLion or in the terminal.

Tbh, it's not worth using bits/stdc++.h. If you type out only the headers you need (with an autocomplete for standard headers maybe), you'll lose some seconds, but on the other hand, you'll save seconds of compilation time because the compiler won't have to go through all the headers on your system and figure out which declarations you need and which ones can be optimised out. When you need to debug and aren't slow at debugging, waiting 2 more seconds for each recompilation can be quite a waste.

           Not sure if this will work on Windows but it's worth a try:  
      

      • Find the file stdc++.h which is referenced by the compiler.
      • Compile the file using the same command line options as usual (warnings, optimizations, etc)

             You should get a file called stdc++.pch right next to stdc++.h. Continue using  
               
             user@home-MacBook-Pro ~ % g++-12 --version  
             g++-12 (Homebrew GCC 12.2.0) 12.2.0

             0 as usual. Next time you compile a file which includes`bits/stdc++.h` you should see a substantial change in compilation time (2-4 times faster)

this video help me to solve the same problem, you can change clang to g++ if you like

First open finder. Then press shift+cmd+G.

Then copy this /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/ and paste it in the box. then click Go.

When you're in v1 folder create a new folder called bits after that create a new file called stdc++.h

Then go to this page: https://github.com/tekfyl/bits-stdc-.h-for-mac/blob/master/stdc%2B%2B.h copy the content and paste it in stdc++.h file and save it.

And that's it.

Well, I find it necessary to install GCC. With GCC there is also pbds, _Find_first, etc... It’s frustrating for me to be unable to use GCC features on my Mac.

• 
  4 years ago, | Rev. 2 0 the way i mentioned above, allows us to us pbds... and all gcc libreries, you can change clang to gcc on that way or you can alse compile using g++8

I was face a same problem with it. after search couple of hour to fix the ‘bits/stdc++.h’ file not found error

Write a simple tutorial how to fix in macOs and windows fix in ‘bits/stdc++.h’ file not found here is the tutorial link. hope this will help

For those who don't still have a problem including the file on macOS

1. go to finder
2. type command+shit+g
3. paste this /usr/local/include
4. create a folder named bits
5. paste bits/stdc++.h inside of it
6. restart your editor

I hope this helps.

Even this video didn't helped me out in order to solve the problem, I am still getting the same error. Should I also have to check other things to work this out?

• 

  12 months ago, | 0 Run g++-12 instead of regular g++. Regular g++ is clang which doesnot have bits/stdc++. g++-12.

  user@home-MacBook-Pro ~ % g++ --version Apple clang version 14.0.0 (clang-1400.0.29.202) Target: x86_64-apple-darwin22.1.0 Thread model: posix InstalledDir: /Library/Developer/CommandLineTools/usr/bin

  The below one is the g++ compiler you need to use(below one is without clang).

Note, g++-12 automatically has bits/stdc++ so you just need to switch the compiler only. No need to copy extra files.

Hi, Can you please tell me which compiler is faster and best among all. I am also using clang in mac.
