DMBS - Dean's Makefile Build System
|
||
|
|
===================================
|
||
|
|
|
||
|
|
|
||
|
|
Project Overview
|
||
|
|
----------------
|
||
|
|
|
||
|
|
GNU Make is scary, and it's tough to get the rules right sometimes. Many
|
||
|
|
projects get by via simple copy-pasting of old makefiles, resulting in many
|
||
|
|
redundant copies of the same old rules. DMBS aims to solve this by providing a
|
||
|
|
simple modular set of makefiles which can be included by your project to quickly
|
||
|
|
add various build functionality.
|
||
|
|
|
||
|
|
This aims to replace the old WinAVR "mfile" makefile template, giving better
|
||
|
|
functionality and much simpler user makefiles.
|
||
|
|
|
||
|
|
|
||
|
|
Benefits:
|
||
|
|
----------------
|
||
|
|
|
||
|
|
Apart from much simpler, cleaner makefiles DMBS carries the aim of making the
|
||
|
|
process of troubleshooting build issues a little easier. Lots can go wrong, so
|
||
|
|
DMBS tries to sanity check its inputs wherever possible, and produce
|
||
|
|
human-readable error messages. Forgotten to set a variable? Get a
|
||
|
|
`Makefile {X} value not set.` message, rather than a possibly unrelated message.
|
||
|
|
Have the wrong filename? See `Source file does not exist: {X}` rather than the
|
||
|
|
infamous `No rule to make target {X}` message.
|
||
|
|
|
||
|
|
|
||
|
|
Use:
|
||
|
|
----------------
|
||
|
|
|
||
|
|
A template user makefile is provided in the `Template` directory. DMBS modules
|
||
|
|
are included via a GNU Make `include` directive. While the DMBS `core` module is
|
||
|
|
always required, you can pick and choose what other modules you wish to add to
|
||
|
|
your user project.
|
||
|
|
|
||
|
|
[See here for the documentation on the individual modules provided by DMBS.](DMBS/ModulesOverview.md)
|
||
|
|
If you're interested in writing your own DMBS module(s), [see here.](DMBS/WritingYourOwnModules.md)
|
||
|
|
|
||
|
|
Here's an example user makefile:
|
||
|
|
|
||
|
|
MCU = atmega128
|
||
|
|
ARCH = AVR8
|
||
|
|
F_CPU = 8000000
|
||
|
|
OPTIMIZATION = s
|
||
|
|
TARGET = Template
|
||
|
|
SRC = $(TARGET).c
|
||
|
|
CC_FLAGS =
|
||
|
|
LD_FLAGS =
|
||
|
|
|
||
|
|
# Default target
|
||
|
|
all:
|
||
|
|
|
||
|
|
# Include DMBS build script makefiles
|
||
|
|
DMBS_PATH ?= ../DMBS
|
||
|
|
include $(DMBS_PATH)/core.mk
|
||
|
|
include $(DMBS_PATH)/gcc.mk
|
||
|
|
include $(DMBS_PATH)/cppcheck.mk
|
||
|
|
include $(DMBS_PATH)/doxygen.mk
|
||
|
|
include $(DMBS_PATH)/dfu.mk
|
||
|
|
include $(DMBS_PATH)/hid.mk
|
||
|
|
include $(DMBS_PATH)/avrdude.mk
|
||
|
|
include $(DMBS_PATH)/atprogram.mk
|
||
|
|
|
||
|
|
Each DMBS module can optionally supply one or more Make variables and macros,
|
||
|
|
which you can reference in your user makefile. Additionally, modules can require
|
||
|
|
one or more variables to be set by the user makefile, with (in some cases) sane
|
||
|
|
defaults used if left out.
|
||
|
|
|
||
|
|
As modules are added, you can get a list of available targets by simply typing
|
||
|
|
`make help` from the command line. This will produce a formatted list of targets
|
||
|
|
as well as mandatory and optional variables and exposed variables and macros.
|
||
|
|
|
||
|
|
|
||
|
|
Distribution
|
||
|
|
----------------
|
||
|
|
|
||
|
|
You can embed DMBS in your project any way you like - some options are:
|
||
|
|
1. A git submodule
|
||
|
|
2. A source tarball
|
||
|
|
3. A manually copied extracted archive
|
||
|
|
|
||
|
|
The intention of DMBS is that users can just import it from whatever source
|
||
|
|
they like. If your project needs to extend the existing modules in an unusual
|
||
|
|
manner, or if you want to provide your own modules, you can include them in
|
||
|
|
your project repository (or submit a patch to DMBS if your module is generic
|
||
|
|
enough to warrant wide use).
