So you mean to say even if GCC compiled libraries are not
using C++11, but migrated components compiled with clang has C++11, when
final executable is created linking all these libraries via clang (GCC
compiled libraries + clang compiled code having C++11) can lead to

I am trying to move to clang compiler from GCC, but our software has tons of components independently developed provding different static archive libraries. All these libraries are finally linked into executable. Now rather than compiling every component with clang from scratch, I was thinking to pick one component at time to compile with clang and use GCC compiled static archives for other components to link into executable using clang compiler. Would this always work ?

Would this always work if I can make sure that our libraries are not using any features of C++11 .
