How can I include in Xcode

Question

I have tried to include the header file bits/stdc++ in my C++ code, but it seems the compiler doesn't support it. Is there any way to make it work?

I use OS X Yosemite 10.10.2 and Xcode 6.1.1.

You aren't supposed to include this header directly. Why do you think you need it? — πάντα ῥεῖ, Mar 11 '15 at 18:06
I used to include it instead of including many other libraries and save myself a time — Omar, Mar 11 '15 at 18:09
@Omar Except you´ll probably get notably increased compile time. Use the standard headers necessary for your used functions/classes, and not some internal G++ file — deviantfan, Mar 11 '15 at 18:13
@Omar _"I used to include it instead of ..."_ That's wrong. The headers appearing in the `bits` directory are meant to bind the c++ compiler implementation with your actual machine and OS environment. These are usually included by the higher level implementations of the c++ standard library headers, sometimes only under certain conditions (`#ifdef`'s) — πάντα ῥεῖ, Mar 11 '15 at 18:13
this library suits my work environment because i need speed in writing, and the high level implementation won't cause any harm — Omar, Mar 11 '15 at 19:11
the thing is, i used to include it on windows, i need a way to make it work on mac — Omar, Mar 11 '15 at 19:12

I'd be tempted to close this, because the answer to this is a clear "Don't!". The question is based on a flawed assumption and the only accepted answer is an atrocity (yes, my opinion) that discourages understanding of the issue. I'm therefore convinced that SO is better off without this Q than with it. — Ulrich Eckhardt, Feb 21 '22 at 18:32
The speed in writing argument is fallacious unless you use the header they way it was intended: to facilitate pre-compiled headers. If you include it without taking the proper steps, your build times increase dramatically, often taking an order of magnitude longer, and quickly eat up the time you saved by not typing the individual headers the program requires. — user4581301, Mar 21 '22 at 19:53

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.)

with the above path , not working for me. But with this path it is working "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/" — GvSharma, Jul 22 '19 at 12:46

Mac OS X 10.9+ no longer uses GCC/libstdc++ but uses libc++ and Clang.

After the XCode 6.0.1 update the headers are now located here:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1

so, get the stdc++.h file from here,then creat bits directory in the above long address, and copy the file stdc++.h to the bits directory.

You can't. X-Code uses LLVM Toolchain with Clang for the compiler, while <bits/stdc++> is specific to the GNU Compiler Toolchain.

Second, you shouldn't be using that header in the first place, as stated by everyone else.

Before Adding the bits/stdc++.h to your mac os platform, the First things are to figure out where your include files are present. To figure out which include file is getting utilized within you mac environment.

Run this command in terminal:

echo "" | gcc -xc - -v -E

This will provide the details of gcc environment in your platform

Go to the include path. ex: /usr/local/include Create a bits folder and add stdc++.h file.

In case none of the above solutions work for you.

Try creating a folder named bits in

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include

[ You can definitely use terminal but if you want to use finder press cmd + shift + G keys (⌘ + ⇧ + G) to goto path menu and paste the above path ]

and create a file named stdc++.h and paste the code for stdc++.h file given here

The reason for that as stated by others also is because Mac OS X 10.9+ no longer uses GCC/libstdc++ but uses libc++ and Clang.

So one alternative way to fix that is to make your default mac compiler from clang to gcc.

As you can see in this image, the default mac compiler is clang.

So, what we can do here is install gcc!

Step 1

Run the following command to install gcc (assuming homebrew is installed on your machine):

$ brew install gcc

Step 2

After gcc is installed note the version by running the following command

$ gcc --version

Step 3

So now when we run g++-version it will use the gcc compiler, but we want it to use gcc compiler when we run g++. For that we are going to create a symbolic link of g++ to gcc:

$ cd /usr/local/bin

Now create a symbolic link by running this command:

$ ln -s g++-[version] g++

(Replace version by your current installed.)

Now restart the terminal for the changes to take effect and run g++ , it will use gcc compiler. It should look like this.

The standard GNU compiler, G++ Does not directly support this header so we include it in the required location using the following steps :

cd /usr/local/include
mkdir bits
nano stdc++.h

then copy the code of the header file from here .

Hope that helps ! :D

After creating a symbolic link to g++ at /usr/local/bin/ it should work.

Command for symbolic link:-

sudo ln -s $(which g++-11) /usr/local/bin/g++

If the bin directory is missing, then create the bin directory first.

The basic solution is to create the bits folder and stdc++.h file where the compiler is looking for its libraries.

To find this for g++ or gcc go to the terminal and write

**g++ -print-search-dirs**

You'll get something like this:

programs: =/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
libraries: =/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/13.0.0

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.

Harshit Jain · Answer 19 · 2022-03-13T06:53:53.050

Header files may contain Function definitions, Data type definitions and Macros

You need to understand that in bits/stdc++.h, bits is the folder name that's useless to you right now, the header file is stdc++.h.

Step 2: Add include "stdc++.h" on top of your file where you want to include this header file, Note: always put path with file name, as if your header file is in C:/Folder1 then you should write include "C:/Folder1/stdc++.h"

if you find any errors while including any header file, that's inside `stdc++.h` header file, simply comment it out from `stdc++.h` file! Ofcourse if file is not important to you, if it's needed find other alternatives! — Harshit Jain, Mar 13 '22 at 06:36

If you update to MacOS 12.3, most of the existing answers on the Internet will fail. Open a folder with this:

open /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs

Or you can directly peel off Xcode layer by layer with the graphical interface. You will see two folders, one with an arrow and one without. like this

Obviously, this is caused by the change of folder path caused by MacOS update. Because the contents of the two folders are almost the same ,you can hardly find out the cause. Your Xcode can find the standard header file(like stdio.h) in the new path, but can't find the stdc++.h you added, because you added it to the old path.

TLDR:

Download the linked file. Go to /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1 and copy the downloaded file to that directory. You can start using #include <stdcpp.h> in your projects instead of manually including all required header files.
