Hi,
I am trying to understand the build process in more detail. I am
currently targeting the AR Drone 2, as such, I followed these
instructions:
http://paparazzi.enac.fr/wiki/AR_Drone_2/getting_startedThe installation was successful, I was able to perform a simple build of ardrone2_raw with target set to AC.
When examining the build logs, I see this command:
=================Copy/paste Begin=============================
RUN 'make -C /home/ub-username/paparazzi -f Makefile.ac AIRCRAFT=ardrone2_raw ap.compile '
make: Entering directory `/home/ub-username/paparazzi'
-----------------------------------------------------------------------
Paparazzi version v5.1_devel-683-g4978164-dirty
-----------------------------------------------------------------------
=================Copy/paste End==============================
Out of curiosity, I tried running the make command from a
regular Ubuntu terminal window, but i get the following error messages:
===================Copy/paste Begin==============================

I think its fairly clear that the Paparazzi utility must be
doing a little more than just running the "make -C
/home/ub-username/paparazzi -f Makefile.ac AIRCRAFT=ardrone2_raw
ap.compile" command. My guess is that its taking the settings from the
GUI and modifying something to allow successful builds (ie: board
selection, XML files for code generation, etc). My questions are:
a) is there any clear/concise documentation of what additional
makefiles are invoked or paths being included with the paparazzi
utility?
b) I've found references to other makefiles, some responsible for setting up other important settings:
paparazzi\conf\boards\ardrone2_raw.makefile <-- talks about device mapping, gps baud rate, USB ports, etc
paparazzi\Makefile
paparazzi\sw\airborn\makefile <--- talks about architecture, in this context, its ARM cross compiler
paparazzi\conf\Makefile.arm-common <--- i can add an echo command here and it appears in the build logs in Paparazzi as well
I'm not sure how
makefile.ac interacts with any of these other
makefiles - from reading
makefile.ac its not clear to me. I have limited experience with writing/interperting makefiles so I
may have missed something obvious.
c) What steps should I take to do builds outside of the paprazzi utility (ie: from the command terminal?)
