Can I use a library developed in c++11 in c++17 code? [on hold]

I'm working on a c++ project and I use c++17 as c++ standard. I've some library dependencies which has been developed using c++11. Are there any obstacles in using this library? Do I need to recompile it using c++17 in order to make sure I can use it in my project? I'm using Clang as compiler in my code and the library has been compiled using g++ .

Many Thanks,
