Summary: target specific variables with conditional
assignments
Project: make

Severity: 3 - Normal
Item Group: Bug

Open/Closed: Open
Component Version: 3.81
Operating System: Any
Fixed Release: None
_______________________________________________________
Details:
If a target-specific conditional variable assignment is used, it
unconditionally overrides any inherited target-specific variable. Try the
following Makefile with and without the first line. The command is always run
with the argument 'two'.
all: TARGET = one
all: lib
lib: TARGET ?= two
lib:
make -f second.mk $(TARGET)
The bug might arguably be that the target-specific variable is being
inherited at all though that's actually a useful feature for me. I can get
this Makefile to work as I want by using $(or $(TARGET),two).
