I have a C++ project with this file structure:

include files:

src files:

In order to compile it and run I'm trying to create simple Makefile. After going through some tutorials, that what i got so far:

vpath %.hpp include

vpath %.cpp src

    agenda: agenda.cpp User.o Date.o Meeting.o Storage.o AgendaService.o AgendaUI.o

        g++ agenda.cpp User.o Date.o Meeting.o Storage.o AgendaService.o AgendaUI.o -o agenda



    User.o:User.hpp User.cpp

        g++ -c -std=c++11 User.cpp



    Date.o:Date.hpp Date.cpp

        g++ -c -std=c++11 Date.cpp



    Meeting.o:Meeting.hpp Meeting.cpp

        g++ -c -std=c++11 Meeting.cpp



    Storage.o:Storage.hpp Storage.cpp

        g++ -c -std=c++11 Storage.cpp



    AgendaService.o:AgendaService.hpp AgendaService.cpp

        g++ -c -std=c++11 AgendaService.cpp



    AgendaUI.o:AgendaUI.hpp AgendaUI.cpp

        g++ -c -std=c++11 AgendaUI.cpp



    clean:

        rm User.o Date.o Meeting.o Storage.o AgendaService.o AgendaUI.o  

And by the way, the main function here is agenda.cpp file. So by executing the make command I'm getting this error:

make: *** No rule to make target 'agenda.cpp', needed by 'agenda'.  Stop.  

My guess is it can't find the path to agenda.cpp otherwise it wouldn't ask to make a rule. Anyway not sure, hope someone could explain.
EDIT.0:

I have edited makefile by adding vpath, but still get the error(new):

g++ -c -std=c++11 User.cpp

g++: error: User.cpp: No such file or directory

g++: fatal error: no input files

compilation terminated.

make: *** [makefile:9: User.o] Error 1  

Seems like this time it found agenda.cpp and User.hpp but can't find User.cpp. Really would appreciate any clue, was working on it for a long time.

EDIT.1:

#VPATH = src:include

#CPPFLAGS = -I include

#vpath %.hpp include

#vpath %.cpp src



bin/agenda: build/User.o build/Date.o build/Meeting.o build/Storage.o build/AgendaService.o build/AgendaUI.o

    @mkdir -p bin   

    g++ -std=c++11 -w -I./include $^ -o $@



build/%.o: src/%.cpp

    @mkdir -p build

    g++ -std=c++11 -w -I./include -c -o $@ $<



clean: 

    @rm -rf build

    @rm -rf bin  

After spending some time on my Makefile, that is the final answer,it compiles fine all *.cpp files, stores obj file in build folder,no problem,except agenda.cpp(main-file),i didn't get my executable file. But got this error:

/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/8/../../../x86_64-linux-gnu/Scrt1.o: in function `_start':

(.text+0x20): undefined reference to `main'

collect2: error: ld returned 1 exit status

make: *** [makefile:8: bin/agenda] Error 1  

How Could i fix this?

Alright i made this Makefile and it compiles and runs just fine, just post it here if someone needs that as a reference.

The study path that i used is:
GNU tutorials
(.text+0x20): undefined reference to `main' and undefined reference to function
C Linking Error: undefined reference to 'main'
