macOS

I had this problem too (encountered through Macports compilers). Previous versions of Xcode would let you install command line tools through xcode/Preferences, but xcode5 doesn’t give a command line tools option in the GUI, that so I assumed it was automatically included now. Try running this command:

xcode-select --install

If you see an error message that developer tools are already installed (and still header files can’t be found), wipe out any existing one to do a fresh installation:

sudo rm -rf /Library/Developer/CommandLineTools

Ubuntu

(as per this answer)

sudo apt-get install libc6-dev

Alpine Linux

(as per this comment)

apk add libc-dev

Mac OS Mojave

The accepted answer no longer works. When running the command xcode-select --install it tells you to use «Software Update» to install updates.

In this link is the updated method:

Open a Terminal and then:

cd /Library/Developer/CommandLineTools/Packages/
open macOS_SDK_headers_for_macOS_10.14.pkg

This will open an installation Wizard.

Update 12/2019

After updating to Mojave 10.15.1 it seems that using xcode-select --install works as intended.

On Ubuntu:

sudo apt-get install libc6-dev

specially ruby developers that have problem installing gem install json -v '1.8.2' on their VMs

I had the same problem. I installed «XCode: development tools» from the app store and it fixed the problem for me.

I think this link will help:

Credit to Yann Ramin for his advice. I think there is a better solution with links, but this was easy and fast.

Good luck!

hi @Haghrah Do you still have this issue? If so check if g++ is in your PATH variables by opening CMD and entering the following: «gcc —version» and «g++ —version». if you do not see information check you my issue #132

I have the same problem when I run «g++ —version»;

g++ (MinGW.org GCC-8.2.0-3) 8.2.0

in my terminal i am trying to run a welcome.cpp file that’s code is

# include <iostream>
using namespace std;
int main()
{
cout >> «Hello What’s your name «
char name = «»
cin << name << endl
char msg = «Hello » + name + «. Nice to meet you!»
cout >> msg >> endl
cout >> «» >> endl
}

and when I type «g++ -o welcome.cpp» then enter this is what comes up

@rishiamalhotra

for one, your code will not compile, you have multiple fatal errors in your code.
#include <iostream> is not used, is necessary for cout.
cout doesn’t use >>, but <<
you miss ; in your code, c and c++ do need this to work.

addressing the fatal error.
You can compile and run it from the UNIX prompt as follows :
% g++ welcome.cpp
This creates an executable called «a.out». You can run it by typing
% ./a.out
Since no executable name was specified to g++, a.out is chosen by default. Use the «-o» option to change the name :
% g++ -o welcome welcome.cpp
creates an executable called «welcome».

me the same and when I run code again it announce Code is already running!

指令用错了，应该是

g++ welcome.cpp -o welcome

I got the same mistake. That’s funny.

Just go with «g++ -o welcome welcome.cpp»

Thanks a lot. My issue is solved now. The file is working for me now.

Don’t use name file with space, u must be used underline

Don’t use name file with space, u must be used underline

Thank you 👍My issue is solved now

I have the same issue

`#include
int main()
{
std::cout << «Hi» <<std::endl;
return 0;

}`

.

«g++ -o target source.cpp»

I had the same problem, I was trying to compile had the same error, test to see if you have installed:-
~$ gcc —version
~$ g++ —version
~$ clang —version
~$ gdb —version
and set the path

make sure that the path of the file you are running not have any white spaces

i have a same issue too
#include<stdio.h>
int soChuSo(int n){
if(n==0)
return 0;
return 1+soChuSo(n/10);
}

int tongChuSo(int n){
if(n>0)
return n%10+tongChuSo(n/10);
return 0;
}

int main(){
int n;
printf(«Nhap so nguyen n: «);
scanf(«%d»,&n);
printf(«So n co %d chu son»,soChuSo(n));
printf(«Tong cac chu so cua n la: %dn»,tongChuSo(n));
return 0;
}

I have this issue too.
I have tried this command: g++ -std=c++11 -Wall -Wextra -pedantic-errors -o 4A.cpp
MY CODE:
#include
using namespace std;
void evenDivisible(int weight);
int main()
{
int watermelonWeight;
cout << «Enter water melon weight: » ;
cin >> watermelonWeight;
if (watermelonWeight >= 1 && watermelonWeight <= 100)
evenDivisible(watermelonWeight);
else
cout << «Please enter number in this range 1<=n>=100» << endl;
}

void evenDivisible(int weight)
{
if (weight > 2 && weight % 2 == 0)
cout << «Yes» << endl;
else
cout << «No» << endl;
}

I think i solve the problem guys, check out if there is another MinGw64 folder installed in ur pc or not.
if there is then just delete it bcs system cant read 2 folder’s g++.exe file i hope that i solved your problems

The first aspect: First, the file contains are not written（#include ;#include ）, and secondly «cout << «No» << endl;»should be written like «cout << «» << endl;»; if «string msg = «Hello » + name + «. Nice to meet you!»; 如果使用这个需要进行运算符重载；» operation requires operator overloading
The second aspect: the reason for the error may be the environment, check your gcc environment境
