Fam Zheng1c33ac52014-05-27 15:54:19 +0800281# unnest-vars
282# Usage: $(call unnest-vars, obj_prefix, vars)
283#
284# @obj_prefix: object path prefix, can be empty, or '..', etc. Don't include
285# ending '/'.
286#
287# @vars: the list of variable names to unnest.
288#
289# This macro will scan subdirectories's Makefile.objs, include them, to build
290# up each variable listed in @vars.
291#
292# Per object and per module cflags and libs are saved with relative path fixed
293# as well, those variables include -libs, -cflags and -objs. Items in -objs are
294# also fixed to relative path against SRC_PATH plus the prefix @obj_prefix.
295#
296# All nested variables postfixed by -m in names are treated as DSO variables,
297# and will be built as modules, if enabled.
298#
299# A simple example of the unnest:
300#
301# obj_prefix = ..
302# vars = hot cold
303# hot = fire.o sun.o season/
304# cold = snow.o water/ season/
305#
306# Unnest through a faked source directory structure:
307#
308# SRC_PATH
309# ├── water
310# │ └── Makefile.objs──────────────────┐
311# │ │ hot += steam.o │
312# │ │ cold += ice.mo │
313# │ │ ice.mo-libs := -licemaker │
314# │ │ ice.mo-objs := ice1.o ice2.o │
315# │ └──────────────────────────────┘
316# │
317# └── season
318# └── Makefile.objs──────┐
319# │ hot += summer.o │
320# │ cold += winter.o │
321# └──────────────────┘
322#
323# In the end, the result will be:
324#
325# hot = ../fire.o ../sun.o ../season/summer.o
326# cold = ../snow.o ../water/ice.mo ../season/winter.o
327# ../water/ice.mo-libs = -licemaker
328# ../water/ice.mo-objs = ../water/ice1.o ../water/ice2.o
329#
330# Note that 'hot' didn't include 'season/' in the input, so 'summer.o' is not
331# included.
