Clang doesn't see basic headers

I've tried to compile simple hello world on Fedora 20 with Clang, and I get the following output:

d.cpp:1:10: fatal error: 'iostream' file not found

#include <iostream>

I don't have any idea how to resolve it.

Solution

  • Point 3 solved the problem for me.

    1. Had the same issue, fedora 21::clang 3.5.0: 

    clang++ -std=c++14 -pedantic -Wall test_01.cpp -o test_01 -v

    2.

    ignoring nonexistent directory "/usr/lib/gcc/i686-redhat-linux/4.9.2/include"
#include "..." search starts here:
#include <...> search starts here:
 /usr/local/include
 /usr/bin/../lib/clang/3.5.0/include
 /usr/include
End of search list.
test_01.cpp:1:10: fatal error: 'iostream' file not found
#include <iostream>

    3.

    sudo yum install gcc-c++

    4.
