This section describes a Cross-Compiler, Cross-Platform (CCCP) makefile development methodology. The syntax to use would be:

make platform.action

(ex: make win, make unix.clean, etc...).

The project filetree

The project should split the code into modules, and each module should be assigned a folder from the root folder. Therefore there would only be a two-level folders tree:

  1. The root
  2. The modules

The project makefiles distribution

The root folder must contain:

  • The Makefile (Makefile)
  • One specific makefile per platform and per compiler (ex: win.mk, unix.mk, etc...)
  • An auxiliary file included in the latter (aux.mk)

And each module must contain:

  • The module standard Makefile (module/Makefile)
  • The dependencies file included in the latter (module/Dependencies.mk)
  • The local environment variables file included in the former (module/Vars.mk)

The makefile's global variables

The idea is to use global variables to pass arguments to the different modules makefiles. Thus, each specific platform makefile in the root folder defines these global variables. Then, it calls the modules makefiles who will use the global variables in their syntax. If a systematic approach of using global variables is implemented, then it is fairly easy to have a cross-platform makefile project implemented; and easily extended.

The Mohid Makefile Project

A sample project for Mohid2D (DEPRECATED)

Here we apply the methodology described above.

Makefile

SHELL = /bin/sh

export MAKE = make
PLATCLEAN = win.clean nix.clean
PLAT = $(PLATCLEAN:.clean=)

.PHONY: default $(PLATCLEAN) $(PLAT)

default:
	@echo Please choose your platform from:
	@echo $(PLAT).
	@echo Type "make win(.clean)" or "make nix(.clean)".

$(PLAT):
	$(MAKE) -f $@.mk all

$(PLATCLEAN) : 
	$(MAKE) -f $(@:.clean=).mk clean

win.mk

SHELL = /bin/sh
