All-in-one about uc-makefile

[jscrane]

A single file is included, uC.mk, which includes all of the other architectures previously included.

Architecture-specific include files, e.g., arduino-esp32.mk, esp32.mk, etc., have defines scoped by the architecture. Thus it should be possible to say,

make -I ~/src/uC-makefile esp32

Backward-compatibility would also be nice: if, e.g., arduino-esp32.mk is included, it should become the default.

a: CPPFLAGS += -I "foo"
a: all
b: CPPFLAGS += -I "bar"
b: all

CPPFLAGS := -I .. -I $@

all:
        echo $(CPPFLAGS)

.PHONY: a/foo b/foo

%/bar: %
        echo $(@D)

For now have bodged this with conditionals and renaming of fragments. However there must be a better solution involving target- and pattern-specific macros.

Think a better solution involves using a prefix macro:

p = foo
foo_board := d1_mini

Then find board and use that to search various board.txt:

board = $($p_board)
