CMake "clang ++ cannot compile simple test program" (Fedora 20)

So I tried to install clang + cmake to compile a simple C ++ program and I get the following error:

-- The C compiler identification is GNU 4.8.3
-- The CXX compiler identification is Clang 3.5.0
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/local/bin/clang++
-- Check for working CXX compiler: /usr/local/bin/clang++ -- broken
CMake Error at /usr/share/cmake/Modules/CMakeTestCXXCompiler.cmake:54 (message):
  The C++ compiler "/usr/local/bin/clang++" is not able to compile a simple
  test program.

  It fails with the following output:

It doesn't even compile my program because it fails to compile the test program.

Looks like an important line:

 /usr/bin/ld: cannot find -lstdc++

      

        
        
        
      

    

However, I have verified that it is libstdc++

installed and updated, so at this point I am completely lost.

Other things I've tried:

• Using prebuilt binaries instead sudo yum install clang
  
  
• uninstall and reinstall
• Tried it clang++ hello.cpp
  
  (hello world program). He says he was <iostreams>
  
  not found. Is clang the missing standard library? EDIT: Going to is <iostream>
  
  giving me the same linker error above.

I'm not familiar with the clang scene, cmake and C ++ in general, so I would appreciate any pointers. Thank!
