Hi!

I just did a fresh install of Ubuntu LTS 14.04 on a virtual machine, and installed using sudo pip install dronekit-sitl.

When trying to open a instance, I get this error:

aldux@ubuntu:~/Flight-Stack/simulator$ dronekit-sitl copter --home=55.870595,-4.287639,0,0

Appears that dronekit-sitl is identifying my system as 'win32'...

Cheers!

One potential issue is that I think the version of PyPi is out of date. Try install sitl from github:

pip install git+https://github.com/dronekit/dronekit-sitl
alduxvm commented 8 years ago

Ok, I uninstalled dronekit-sitl, then I did: sudo pip install git+https://github.com/dronekit/dronekit-sitl

Then again tried to open it:

same stuff... :(

hamishwillee commented 8 years ago

Its a bugger. I've not been able to reproduce this on this same ubuntu in a VM :-(

@peterbarker Any suggestions? We've seen this before, but I personally can't get it to "fail".

alduxvm commented 8 years ago

I had an old VM with Ubuntu 14.04... updated and the installed and worked excellent...

Then I created a new one, brand new, "fresh" VM with the same ubuntu 14.04 and this problem started...

hamishwillee commented 8 years ago

I just completely reinstalled VM on Windows 10 of Ubuntu 14.04 and it worked fine ..... As you say, same Ubuntu 14.04. I don't doubt that you have a problem, I just can't get it to fail in the same way.

alduxvm commented 8 years ago

I manage to get a work-around for this situation... I compiled ArduPilot like this:

git clone git://github.com/ArduPilot/ardupilot.git
cd ardupilot/ArduCopter
make -j4 sitl

And then to execute: dronekit-sitl ./ardupilot/ArduCopter/ArduCopter.elf

Is not ideal... or as easy as just using pip, but is working...

Interesting. The fact that you can launch native binaries implies that the original error report is accurate - i.e. that you've been downloading binaries that aren't native or aren't detected as native. @peterbarker Any ideas how we might debug this?

We should add a check into dronekit-sitl which warns when you try to download on a non-supported platform and dies with a clear error when you try torun on non-supported platform.

But first we should do a fresh release of dronekit-sitl which includes the start_default entry point. I haven't worked out why people are getting a dronekit-python from the git repository when using pip with default settings.

hamishwillee commented 8 years ago

OK, can you make that release? ... or do you not have the magic power?

ggregory8 commented 8 years ago

Hi, I'm having the same issue on Ubuntu 14.04.4 LTS using master. Any news on this?

hamishwillee commented 7 years ago

Almost certainly running SITL on an ARM platform. Binaries are no supplied, though you can build your own.

EfranDev commented 7 years ago

What could I do? It never happened to me.

kevinjhur commented 7 years ago

I think this error is from that dronekit sitl can not support 32 bit linux OS. Below is my try, please refer. on Ubuntu 14.04 64bit with intel PC -> works fine on Ubuntu mate 16.04 with Raspberry -> works fine on Ubuntu 14.04 with Odroid ux4 -> Error same as above

Ahmad-Drak commented 7 years ago

Same issue here. Tried it on Odroid XU4 running Mate 16.04 resulted in the same error. Any fix for that?

I am trying to interface the raspberry pi with the pixhawk through serial pins on raspberry pi. I am able to get a connection between the two.

I get the following messages after setting up the connection i@raspberrypi:~ $ sudo -s root@raspberrypi:/home/pi# mavproxy.py --master=/dev/ttyACM0 --baudrate 57600 --aircraft plane Connect /dev/ttyACM0 source_system=255 no script plane/mavinit.scr Log Directory: plane/logs/2017-12-15/flight1 Telemetry log: plane/logs/2017-12-15/flight1/flight.tlog MAV> Waiting for heartbeat from /dev/ttyACM0 *o]l`:H9%online system 1 ALT_HOLD> Mode ALT_HOLD [S$<f1z9;>;APM: APM:Copter V3.5.4 (284349c3) APM: PX4: 0384802e NuttX: 1bcae90b APM: Frame: QUAD APM: PX4v3 00490021 33355119 38393235 Received 773 parameters Saved 773 parameters to plane/logs/2017-12-15/flight1/mav.parm fence breach mode ALT_HOLD> ('Available modes: ', ['RTL', 'POSHOLD', 'LAND', 'OF_LOITER', 'STABILIZE', 'AUTO', 'GUIDED', 'THROW', 'DRIFT', 'FLIP', 'AUTOTUNE', 'ALT_HOLD', 'BRAKE', 'LOITER', 'AVOID_ADSB', 'POSITION', 'CIRCLE', 'SPORT', 'ACRO'])

After this i tried writing a python code to get some data from pixhawk I followed the steps here http://python.dronekit.io/guide/quick_start.html#installation

but then i get this error pi@raspberrypi:~ $ sudo python hello.py Start simulator (SITL) Starting copter simulator (SITL) Downloading SITL from http://dronekit-assets.s3.amazonaws.com/sitl/copter/sitl-linux-copter-3.3.tar.gz Download Complete.

Any help would be appreciated. Stuck at this from quiet long.

Thanks & Regards

@hamishwillee :+1: In issue #95 : you said we cant use it on an arm processor. So using raspberry pi as ssh and using on my laptop with intel processor would have a difference???

hamishwillee commented 6 years ago

Yes. Only intel binaries are supplied.

Slight clarification though. You can't use ARM "out of the box" because no binaries are built for ARM processors. If you wanted though, you could build the binaries yourself on the platform you want to run them, and then use SITL to launch them.

mandar-bhide commented 3 years ago

Everyone's saying "You can build your own binaries for ARM platform". Please explain HOW???

I'm getting the same thing on my Raspberry Pi
