I followed this tutorial (here) to get Clang working on windows. I choose the path to install clang in combination with msys2.
After following all instructions I wrote the simple programme:
#include <iostream> using namespace std; int main() { cout<<"Hello, World!\n"; return 0; } After compiling with: clang++ Helloworld.cpp -o Helloworld.exe -std=c++14
I get the error:
*Helloworld.cpp:2:10: fatal error: 'iostream' file not found,
1 error generated.*
Adding -v in the command line I get:

Helloworld.cpp:2:10: fatal error: 'iostream' file not found #include <iostream> ^ 1 error generated. How do I get the system to find iostream? I read something about,that you have to point to the mingw headers in clang/lib/Frontend/InitHeaderSearch.cpp. I couldn't find the file InitHeaderSearch.cpp on my computer.
Thank you for your help.
Windows 8 Clang 3.9.1
