Using make to create directories

[Ian Lynagh]

Hi all,

I would like to use make to create directories, something like this
(which works):

# --------------
default: a/b/c/

a/b/c/ : | a/b/
        mkdir $@

a/b/ : | a/
        mkdir $@

a/ : | ./
        mkdir $@
# --------------

but I don't want to have to have an explicit rule for every directory;
instead I want something like this (which doesn't work):

# --------------
.SECONDEXPANSION:

default: a/b/c/

% : | $$(dir %)
        mkdir $@

./ : ;
# --------------

Please can you tell me if there is a way to do this?


Thanks
Ian
