Why doesn’t Clang recognize the basic header (iostream)?

Question

Command line :

clang++ "C:\caminho\completo\helloworld.cpp" -o "C:\caminho\completo\helloworld.exe"

Code :

#include <iostream>
using namespace std;
int main(){
    cout << "Ola Mundo" << endl;
    return 0 ;
}

Error :

C:\caminho\completo\helloworld.cpp:1:10: fatal error: 'iostream' file not found
#include <iostream>
         ^
1 error generated.

I have already taken a look through the internet and for the brief that I understood it should use the libc++ of mingw, if so, what purpose to exist the Clang ?

Answer 1

As far as I know, Apple created the CLANG pq GCC uses the GPL license. Apple needed to implement some "language improvements" to support its products, and if they implemented these improvements in GCC, they should release the code to the GNU community.

Creating CLANG, they used another license type, which allowed Apple to have private CLANG branchs and not be required to release the source codes.

In your case, if you have the need to use CLANG, install the libstdc++ that everything will work.
