Compile error: undefined reference

hi, I am compiling the code but the errors are like this:

Does your loader_alov.cpp include helper.h header file? Seem like loader_alov.cpp can not find these undefined functions, which are all declared in helper.h and defined in helper.cpp

My error is like this,could you please give me some advices?
