Question

Here’s my makefile

all: main.o fileparam.o
        g++ -g $(LIBPATH) $(LIBS)  file_parameters.o main.o -o test
main.o: main.cpp
        g++ -g -Wall $(INCPATH) main.cpp -c

fileparam.o: file_parameters.cpp file_parameters.h
        g++ -g -Wall file_parameters.cpp -c

$(LIBPATH) $(LIBS) points to the libraries to be included and $(INCPATH) points to other included files

For some reason it recompiles file_parameters.o every time I make the program, and I was wondering where I screwed up. Thanks!

Edit: It does not recompile main.o every time

Answer 1

This:

fileparam.o: file_parameters.cpp file_parameters.h
        g++ -g -Wall file_parameters.cpp -c

should be:

file_parameters.o: file_parameters.cpp file_parameters.h
        g++ -g -Wall file_parameters.cpp -c

Also, calling your output file test may cause confusion – change it to mytest.
