title: Mysterious linker error "undefined reference to `__gxx_personality_v0'" using clang in cygwin
body: <p>I did some search, all answers seem to suggest that using clang++ instead of clang (or rather g++ in place of gcc), which is what I did in the first place. Still, the problem persists, with either</p>
  
  <pre><code>clang++ -Wall -std=c++11 -o test.exe test.cpp A.cpp B.cpp etc.cpp
  </code></pre>
  
  <p>or</p>
  
  <pre><code>clang++ -lstdc++ -Wall -std=c++11 -o test.exe test.cpp A.cpp B.cpp etc.cpp
  </code></pre>
  
  <p>The compilation and linking works fine with g++ in Cygwin.</p>
  
  <pre><code>g++ -Wall -std=c++11 -o test.exe test.cpp A.cpp B.cpp etc.cpp
  </code></pre>
  
  <p><strong>Update:</strong></p>
  
  <p>Here is the information during linking. Is clang trying to use gcc for linking, rather than g++? In that case, why didn't flag -lstdc++ and the -lsupc++ as suggested below, work?</p>
