Makefiles improvements

[barthess]

Hi, Giovanni.
I have some idea about make system improvements.
It will be convenient to has "MAKE_ALL_RULE_HOOK" in rules.mk for simplification of adding user rules to Makefile.

For example I want to see how much rom and ram will use my program in MCU. Yes, I can investigate my ch.map and check size of ch.bin. But it will be better to get this info in console just after building. I write simple script and add

Code: Select all

MAKE_ALL_RULE_HOOK: ram

ram: $(PROJECT).map
   ./ram_usage.sh


strings to my project Makefile.

I can realize this feature and contribute patch if need.

OK, submit the patch, it does not look it can impact anything.

patch here

I just updated the rules.mk files, there are way too many Makefile files to update.

barthess, Just curious, how does your ram check script look like?

[barthess]

It is quick and dirty shell script.

Nontheless some great ideas, thank you barthess

Hi,

I need to create some extra targets (headers+libraries) prior to actually compiling the ChibiOS-based code. One hack I found to work is based on adding a `PRE_MAKE_ALL_RULE_HOOK`, similar to the (then renamed) `POST_MAKE_ALL_RULE_HOOK`.

Thoughts? Other ideas to achieve this? Any chances in getting something like the attached patch merged?

Edit: I created a ticket on source-forge. Sorry for the noise...

Attaching patch-files directly is not allowed, but adding them zipped is?

I saw the tickets, thanks, I can forget things posted on the forum but not tickets.

Any example of how this is used? My makefile-fu is a little low at this time.

I want to run a python-script to generate some *.c and *.h files before compilation and the PRE_MAKE_ALL_RULE_HOOK seems lite the way to accomplish that without hacking anything other than the project makefile.
