.INIT capability in gnumake
ja...@reshape.com
I am trying to implement .INIT capability in SunOS "make" with gnumake.
Here is what .INIT does:
.INIT: If defined in the makefile, this target and its
dependencies are built before any other targets
are processed.
I tried using "%:" and GNUmakefile workarounds with gnumake but they
don't work extactly in the same way .INIT does. Does anyone know a
way to make gnumake to coerce it into behaving like it understands
.INIT.
A side question, why gnumake doesn't have such default target (it is
very useful).
Thanks in advance.

Use $(shell ...) in conjunction with :=. See the GNU make manual for
details.
For example, I always use something like this to create object
directories:
__junk := $(shell [ -d $(OBJDIR) ] || $(MKDIR) $(OBJDIR))
This isn't identical to some implementations of .INIT; some guarantee
they won't be invoked unless some target is going to be built; this will
happen every time make is run.
On the other hand, it's more flexible since you can put as many of these
lines as you like anywhere in your makefiles.
