Programming :: Undefined Reference To 'main' Error In Crt1.o Function _start

I've having problems with my Makefile.

I'm trying to create a program from 2 files - main.cpp that contains the main function, and modules.c that contains the definitions of the functions that are called in main(). modules.c only contain function definitions, no main function.

My Makefile is as follows:

Code:

I have included "modules.h", which contains all the function declarations, in my main.cpp.

When I try to make using this Makefile, I get the error

Code:

If I switch the order of modules.o and main.o in my $(TARGET) line, then I get errors that say "undefined reference to" the functions I have defined in modules.c, in main.cpp.
