[Pcsclite-muscle] unresolved symbols

[Allen Curtis]

I am trying to compile the sample code provided for pcsclite. All the headers and libraries are installed. I can see that the following symbols are defined in the shared library but I get unresolved symbol messages when compiling. How do I resolve undefined symbols below.

Thanks
