Cannot link to shared library

Question

I\'m trying to compile a minimal shared library and link to it and have been failing for two hours now. Here is ALL the code:

// rect.h
class Rect{
  private:
           


        

Answer 1

The libraries have to go after the local translation units:

g++ -L. -Wl,-rpath,'.' client.cpp -o client -lrect
#                                           ^^^^^^

It has to do with how unresolved symbols are looked up by the linker; search the internet for a plethora of information on this if you're curious.
