Makefile creation for subdirectories Makefile

Question

I'm new to Makefile and I have to create a Makefile for my project.

project
├── Makefile
|
├── application
│   |── code1
│   |   ├── header-->header1.h(Inside the header1 folder)
│   |   |── source-->main1.c(Inside the source1 folder)
|   |   ├── doc-->Makefile
|   |
|   |── code2
|   |   ├── header-->header2.h(Inside the header2 folder)
|   |   |── source-->main2.c(Inside the source2 folder)
|   |   ├── doc-->Makefile

For this project , how can I write the Makefile for inside the code1 & code2 and the overall one Makefile How to create the overall Makefile to run the subdirectories Makefile

Answer 1

Something like this?

.PHONY: all
all: application/code1/exe1 application/code2/exe2

application/code1/exe1: application/code1/source/main1.c application/code1/header/header1.c

application/code2/exe2: application/code2/source/main2.c application/code2/header/header2.c

The application/ level adds to the pain here; perhaps you should remove it. Alternatively, maybe put the Makefile in application and remove the toplevel directories in the above.
