So I have been struggling to get my code to compile over the last few hours and I can not understand where I am going wrong.
This is my make file:
This is the output:

Basically my math.cpp and helper.cpp files contain some functions that are used in ECGFitter.cpp, ECGSmoother.cpp and KalmanFiltering.cpp. I understand that you need only to include the .hpp file for the assembler to produce your .o file and then you need to link the .o file of the corresponding source code before you run the linker. I thought I was doing this just fine but clearly I am not.
Thanks for the help!
