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.

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.

I use mac and the following includes do the trick almost all the time (atleast till problem D)

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

TUTORIAL

If you have more suggestions please tell me I will add

For Xcode 13 or later do this :

1. In finder, press Cmd+Shift+G

2. Paste : /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1

3. Create a new folder "bits" here

4. Download the file or create "stc++.h" and paste the content from: https://gist.github.com/frankchen0130/9ac562b55fa7e03689bca30d0e52b0e5

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.

Step 1: Install linux.

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?

I know this is an old post, but I kept finding it when I search this problem, so I wanted to share my 2024 solutions. To fix the missing <bits/stdc++.h> file we have these options for each of the two compilers in MacOS:

Xcode Clang

You can install Clang without the Xcode app from the App Store with: xcode-select install. To install the stdc++.h header file, you need to create the bits folder inside /usr/local/include/, then you need to define _GLIBCXX_HOSTED inside the stdc++.h for it to work, then append the rest of stdc++.h from the gcc mirror repo on GitHub. The commands are as follows:

mkdir /usr/local/include/bits
echo '#define _GLIBCXX_HOSTED 1' > /usr/local/include/bits/stdc++.h
curl -sS https://raw.githubusercontent.com/gcc-mirror/gcc/master/libstdc%2B%2B-v3/include/precompiled/stdc%2B%2B.h >> /usr/local/include/bits/stdc++.h

the downsides are that you may need to manually remove these headers: <cstdalign>,<cuchar>,<memory_resources> in order for clang to work, and that tree_policy may still not be usable

GNU gcc

You can easily download gcc from homebrew, then you need to remove the g++ to clang simlink in /usr/local/bin, then create a simlink for the gnu g++ compiler. The commands are as follows:

brew analytics off # not necessary, but I didn't know that homebrew had analytics
brew update && brew install gcc
sudo rm /usr/local/bin/g++
sudo ln -s $(ls /usr/local/bin/g++-*) /usr/local/bin/g++
