Re: [Paparazzi-devel] Question about a compile error

[Gareth Roberts]

Hi David,

Do you have an IMU calibration file included in your airframe, or the stuff from one?

There is an up to date example here:

https://github.com/paparazzi/paparazzi/blob/v3.9/conf/airframes/esden/calib/asp21-000.xml

I know that one works, at least with a Lisa/M 2.0 + aspirin 2.0.

I couldn't find one for a PPZIMU.

The IMU subsystem pages is helpful for figuring out what the parameters are: http://paparazzi.enac.fr/wiki/Subsystem/imu

You may also need to create a fresh calibration: http://paparazzi.enac.fr/wiki/ImuCalibration#Finding_Signs

You then need to use the include directive in your airframe file, for example:

<include href="">"conf/airframes/UoM/calib/asp21-straight.xml"/>

Cheers,

Gareth

Hello all,

I have come full circle. This is the reason I deleted all the files under var/*

make[1]: *** [/Users/bmw330i/paparazzi-software/var/UMARIML01/ap/firmwares/fixedwing/main_ap.o] Error 1

make: *** [ap.compile] Error 2

I believe it is related to my selecting "ppzuav" as the imu type. I'm not sure where or what file to add the IMU_GYRO_P,Q, R and ACCEL_X,Y,Z

I am trying to compile an airframe that is a TWOG+ppzimu+GPS with the above errors that appear new. 

Regards,

David

Hi David,

messages.h shoud be in var/include/

If not, run make again...

Cheers, Felix

Hello,

Thank you. Yes, it seems obvious but I didn't want to assume.

I'm using the "production" version of Paparazzi (v39). So it must be environment on my end because messages.h seems to be #include(d) in most everything.
