I recently bought a new MacBook on which I transferred my old session. Since then, and after i upgraded to 10.13, i can't get clang to compile anything including only iostream.
Given this program :
#include <iostream>
int main(void)
{
std::cout << "Hello world !" << std::endl;
return 0;
}
gives my this output when g++ main.cpp :

I tried the following :
- Reset CLT with
Xcode-select --reset - Reinstall CLT
- Reinstall Xcode
None of these solution worked and this starting to drive me crazy. Does somebody has the same problem and found a solution ?
EDIT : Xcode C++ Projects are successfully compiling, still don't understand why it would not in a terminal.

I had exactly the same problem after transferring to macOS High Sierra (though, errors were not the same, but similar).
I found a workaround by renaming /usr/local/include to /usr/local/include_old (well, name does not really matter, just the fact that g++/clang will not search for headers in this folder anymore).

I had exactly the same problem today and after executing xcode-select --install, everything works fine!
I had the same issue after upgrading to MacOS Mojave 10.14.4 and Xcode 10.2
The issue got resolved, after installing the package /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

I had a similar issue that after upgrading to high sierra (and Xcode 9.1) that my standard make reported unfamiliar warnings.
It drew .h files from /usr/local/include instead from the (as I thought) standard /usr/include. For example, there was no zlib.h available.
Reinstalling Xcode (who claims to install the commandline version too) did not help.
There was no /usr/include at all but the C++ system include were available through the links reported in clang --version, but none of the C-includes.
After xcode-select --install and actually "install" of the commandline material the /usr/include was populated with the necessary C libraries, and make started to compile without warnings again.
Check that you don't include "/usr/local/include" into headers search path of your project.
