These were dropped accidentally, I assume, during the Configtool
template conversion. Without them the INTERCOM feature does not
compile and so board.gen3.h is broken.
Add the gen3 config to testcases and regressiontests to ensure
this does not drop again.
We should not fail the regression test if the user's config is
missing or misconfigured.
Also turn on -Werror for simulator validation, too. This might be
a bit presumptuous since we are dependent on the user's installed
gcc instance; but we already depending on him to be able to build
the simulator at all, so this doesn't seem to be too much of a
stretch.
For now this is just a number of different configurations and a
makefile target, "make regressiontests", to build with them.
Further tests, e.g. using SimulAVR or the hostside simulator
to check actual behaviour of the firmware are welcome.
- "Traumflug" and "Markus Hitter" are the same, mention him only
once.
- Add more common F_CPU choices in comments.
- Hint to another choice in Makefile-example.
Move builds for non-avr target (simulator) into a $(BUILD_FLAVOR)
build subdir (build/sim) to isolate it more completely and
cleanly from the AVR builds. This allows AVR and SIM to use common
build rules again.
Move newly bits out of Makefile-{SIM,AVR} and into Makefile-common.
Test code which wants to customize config.h can do so without
touching config.h itself by wrapping config.h in a macro variable
which is passed in to the compiler. It defaults to "config.h" if
no override is provided.
This change would break makefile dependency checking since the selection
of a different header file on the command line is not noticed by make
as a build-trigger. To solve this, we add a layer to the BUILDDIR path
so build products are now specific to the USER_CONFIG choice if it is
not "config.h".
Dependency automation seems a bit confused in these makefiles.
Clean it up following ancient sage wisdom here:
http://mad-scientist.net/make/autodep.html
In short, use -MMD to generate dependency files for each .o target,
and then use a sed script to extend that to avoiding "missing file"
dependencies when headers are renamed/removed.
Also, make everything dependent on makefiles other than our
autodependency (*.P) makefiles.
Make the BUILDDIR an order-only prerequisite for our targets so any
changed file therein does not cause all other files to appear to be
out of date.
Also, some makefile cleanup:
- Remove obsolete 'depend' target.
- Move AVR-specific targets to AVR makefile.
- Add TARGET variable to identify target to make and to clean.
- Tidy up dependency make.
We have now Makefile-AVR - AVR specific stuff - and
Makefile-common - common build instructions.
This effort is the begin of preparing Teacup for ARM targets.
To build the target, copy or link Makefile-AVR or Makefile-ARM
(depending on your target) to Makefile.
