ERROR: <bits/stdc++.h>, 'cstdalign' file not found, running C++17
Modified 1 year, 1 month ago Viewed 9k times 4
I'm trying to run a piece of code in Visual Studio Code, on macOS Catalina. The code:
#include <bits/stdc++.h>
using namespace std;
int main()
{
// Create an empty vector
vector<int> vect;
vect.push_back(10);
vect.push_back(20);
vect.push_back(30);
for (int x : vect)
cout << x << " ";
return 0;
}
When I try to run the code using the coderunner extension, I get the error:
[Running] cd "/Users/VSC_Files/" && g++ -std=c++17 helloworld.cpp -o helloworld && "/Users/VSC_Files/"helloworld
In file included from helloworld.cpp:1:
/usr/local/include/bits/stdc++.h:57:10: fatal error: 'cstdalign' file not found
#include <cstdalign>
^~~~~~~~~~~
1 error generated.
[Done] exited with code=1 in 1.465 seconds
Apparently this is an error only for C++11, then why am I getting this error? I have the latest updated Xcode version and the latest stable build of VSCode too.
EDITED AND ADDED LATER
Also, I would like to add that I manually added the bits/stdc++.h file, and that it wasn't there from before.
Also, when I change g++ -std=c++17 to just g++ when running, the program runs and shows the correct output. With a warning as shown below.helloworld.cpp:13:15: warning: range-based for loop is a C++11 extension [-Wc++11-extensions]
Is there an issue with the default C++ version in mt laptop? Please help!

4#include<bits/stdc++.h> is an internal header for the GCC and you are not supposed to use it, it's not portable.
remvoe the #include<bits/stdc++.h> insted write #include<vector> and #include<iostream> also remove using namespace std it considered bad practice so you code shod look like this:
#include <vector>
#include <iostream>
int main()
{
// Create an empty vector
std::vector<int> vect;
vect.push_back(10);
vect.push_back(20);
vect.push_back(30);
for (int x : vect)
std::cout << x << " ";
return 0;
}

- 2 Yes, I realise that does work. But I was wondering why the error I indicated when we use <bits/stdc++.h> was coming. Any idea? – Shravan Jul 13, 2020 at 13:37
- 1 <bits/stdc++.h> is internal header could be that part of the header files its including are not in the macOS c++lib is also indecate that from the error message - he cant find "#include <cstdalign>" – yaodav Jul 13, 2020 at 13:40
- I've added some more info, if that helps! – Shravan Jul 14, 2020 at 0:46
- According to what version of g++ you have 4.2.1 I don't think it supports c++ 11 try updating your gcc version. – yaodav Jul 14, 2020 at 5:59
- solved the issue, and subsequent issue comes again, so I continue comment out the error line. It worked! – Jackson Feb 3 at 10:37
I was having the same issue. First I installed gcc via homebrew
brew install gcc
To avoid conflict with the existing gcc (and g++) binaries, homebrew names the binary suffixed with version. At time of this comment, the latest was gcc-10.
You dont have to copy the bits/stdc++.h after this. Just compile using g++-<major-version-number> instead of g++, which would use the homebrew installed binary instead of the default osx one. For me it is
g++-10 -Wall -O2 -std=c++11 test.cpp -o test
To check the binary name that homebrew installed you can look in the /usr/local/bin directory because thats where homebrew installs packages.
Also, make sure that usr/local/bin is before /usr/bin in your $PATH

Also, I am not disagreeing with the other comments saying that we should not use
bits/stdc++.handusing namespace std;in our code. I put this here, because its good to know how to make it work if we have to use it. – Himanshu Tanwar Sep 14, 2020 at 17:47
For me it worked to comment the following lines out in the file bits/stdc++.h:
// #include <cstdalign> ... // #include <cuchar>
The file is located in /usr/local/include/bits/ as well as in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/bits. I don't know if you have to do it in both files but the first one worked for me!
Update Dec 24: If you use the g++ with the command line, there is no need to move any file into any directory!
For example when I use the command: g++ custom_file.cpp it works fine! In addition you can add -std=c++11 to have the most needed functions. Also I don't have to move the bits/stdc++.h file after Xcode get's an update.
I hope this helps!

Any answer that recommends either editing or explicitly using the
bits/stdc++.hheader is, IMHO, utterly misleading. – Adrian Mole Nov 22, 2020 at 19:26 -
According to this answer MacOSX does not have the file
uchar.hso you cannot#include <cuchar>. Maybe you can download it e.g. from here and paste it to the right directory. I haven't tried this yet. – Chrissi Nov 22, 2020 at 22:43
I too got these error, and I solved these error by commenting out the <cstdalign> part.
After you comment out these line it will give 2 more errors - cuchar not found, and <memory_resources> not found, comment both of them using " //" . It will not harm you stdc++.h file . And it will definitely work.

I am sharing steps to execute with sample code for array rotation which works with following commands
g++-10 -Wall -O2 -std=c++11 rotatearrayusingdeque.cpp
Then a.out file gets generated.
./a.out
sample code:
#include <iostream>
#include<bits/stdc++.h>
using namespace std;
int main()
{
int n,r,i,j,temp=0,n1;
deque<int> v;
cin>>n>>r;
for(i=0;i<n;i++)
{
cin>>n1;
v.push_back(n1);
}
for(j=0;j<r;j++)
{
temp = v.front();
v.pop_front();
v.push_back(temp);
}
for(auto x:v)
{
cout<<x<<" ";
}
cout<<endl;
return 0;
}
Now, there will not be any error, Thanks
