makefile recursion all subsystems always up to date
I'm trying to create a recursive makefile but the make just reports all my subsystems are up to date when there are no object files, executables or even makefiles in the subdirectories.
coco:
if [ ! -f ./CoCo/makefile ]; then cp ./CoCo/Makefiles/Linux/makefile ./CoCo ;fi
$(MAKE) -C CoCo
becker:
if [ ! -f ./becker/makefile ]; then cp ./becker/Makefiles/Linux/makefile ./becker ;fi
$(MAKE) -C becker
...
The first thing I would like to do in each subsystem is ensure the makefile exists and if it doesn't then copy it from the appropriate location.
Next I would like it to change to the subdirectory and perform the make.
Lastly how would I make all subsystems with one command like (make all)?

In case you triedmake beckerit probably reports "all up to date" because there is a directory with namebeckerand it exists and has no dependencies, so nothing to rebuild. As formake cocoI don't know since the dir is apparentlyCoCoand case matters in linux... Does it work same formake coco?

The appropriate location is the source of the cp command.

@igagis Yes it does the same for CoCo. I get the impression I need to explicitly perform the if with a shell!

@igagis You were correct. Mingw on Windows is not case sensitive.
