Building Example Sketches

General Website and Documentation errors
1

Hello

I was trying to follow the steps on the website below

http://ardupilot.org/dev/docs/learning-ardupilot-the-example-sketches.html

However i am facing the problem that

~/ardupilot/libraries/AP_InertialSensor/examples/INS_generic$ make px4-clean
make: *** No rule to make target ‘px4-clean’. Stop.

How can it be fixed?

I have same problem. I could not find any make file in that directory

3

I want to compile and upload example sketches to my pixhawk,and I am facing the same problems…

4

The build system is changed to waf now. In fact the page in the link has been updated to talk about how to build the examples with waf

I have same problem. I could not find any make file in that directory

We no longer use the make build system for our examples.

We now use “waf”; I’ve updated the instructions on the wiki to reflect
that.

Additionally, the INS_generic example is currently broken. I have created
a pull request (AP_InertialSensor: fix INS_generic example (call BoardConfig.init()) by peterbarker · Pull Request #5055 · ArduPilot/ardupilot · GitHub) to fix
that, and in the meantime try one of the other examples (the DataFlash
example is pretty verbose - and just tested :slight_smile: ).

Hi guys,

I have a problem with building example sketches… I can’t build them, always get the same error doesn’t matter which sample I wanted to build.
I’m following this instructions:
http://ardupilot.org/dev/docs/learning-ardupilot-the-example-sketches.html#library-example-sketches

So when I want to build the code with ./waf build --target examples/INS_generic --upload
I got error in libraries/AP_ADSB_AP_ADSB.cpp in line 594.
It says:
error: ‘snprintf’ output may be truncated before the last format character [-Werror=format-truncation=]
uint8_t AP_ADSB::get_encoded_callsign_null_char()
^~~~~~~
compilation terminated due to -Wfatal-errors.
cc1plus: all warnings being treated as errors

I assume that maybe the problem is in px4 fw_io because last build is here and after this build failed.
[462/470] CMake Build px4 fw_io
ninja: no work to do.
…/…/libraries/AP_ADSB/AP_ADSB.cpp: In member function ‘uint8_t AP_ADSB::get_encoded_callsign_null_char()’:

I stopped here and don’t know how to fix this problem…
Maybe someone had the same or similar problem in the past???

Thank you!

Same error there. I was trying to build a custom version of Arducopter for Pixhawk 2 with make px4-v3.
Did you ever find out the cause/fix?

Yutaoliu, unfortunately i didn’t.
Did you maybe try to build it with waf (./waf) ?
I’m using Pixhawk 1…
