Make posix jmavsim error

1

hello the PX4 gurus
I still wondering to have a dev environnement and it looks not so easy
I folowed 2 or 3 times the documentation

  • setting the user to dialout group

  • removing modemmanager

  • sourcing ubuntu_sim.sh and ubuntu_sim_nuttx.sh
    all on a fresh ubuntu 16.04
    I tried on 2 differents computer one with a virtualbox ubuntu and the other with an ubuntu alongside a windows
    on both I get the same issue when trying the make posix jmavsim

    $ make posix jmavsim

does any one get this too?

the git update and the compile part looks ok but sommthing looks missing when launching the PX4 and the jmavsim env

I seen somthing that could looks similar at first sight here running JMAVSim in vmware fails · Issue #42 · DrTon/jMAVSim · GitHub but solution look’s not applicable I didnt find the same files and or dir structure … :disappointed:

thank’s for any help

2

same issue using docker
any help would be greatly apreciated

There is a recent incompatibility with running jMAVSim in a VM (oracle or vmware). This should however work on a real Linux computer.

What does work quite nicely is this “not quite submitted” Windows Cygwin solution: https://github.com/PX4/Devguide/pull/522 (or even better link - see https://github.com/MaEtUgR/Devguide/blob/83c7d87dba2cc9c9b035f0340277d0a3c8661c74/en/setup/dev_env_windows_cygwin.md )

This works, we’re just getting together documentation so that it can be maintained going forward.

thank’s a lot for your kind answer
I tried on a real linux ubuntu (not VM) a 16.04 using convenience scripts and a 18.04 using docker containers(because fastRTPS doesent compile under 18.04) and I facing always some issue (i did not try under windows yet)
with 16.04 the issue is the one mentioned above
with 18.04 with docker container the issue is

it dont find jmavsim_run.jar witch realy doesn’t exists
thank’s again for you answer I was starting to feel a bit alone

Hi,

Yesterday I succeeded in building 1.8.0beta2 on 18.04. Sitl with jmavsim worked on my system.
If you’re still stuck let me know.

The jmavsim_run.jar can be built from the Firmware/Tools/jmavsim directory using:
ant clean distro

(I switched to the java 8 alternative atm, the vecmath-patch for java 10 is not yet in the latest update… Will be very soon)

Regards,
Yuri

Hi, you could try to replace openjdk to oracle jdk .

7

Hi,

I just tested it.
If you meant oracle jdk 10, that doesn’t build due to the missing vecmath.jar.
Oracle jdk8 does work with jmavsim.

Yuri

Hi ，
Someone told me that he make posic jmavsim error ,and he solved this by replacing jdk.
I did not verify that it is feasible. I will try it later.
And I have a problem. The problem is that I don’t know how to utilize the port as an input and pass that info to a mavlink message. I know there are example about connecting external sensor such as air speed or sonar data as adc input but not that I know about connecting pulse signal output as input to pixhawk.
Do I have to make an module just for this? or any step by step method to configure the input?
Thanks.

thank’s I’m still discovering PX4 ecosystem and trying to make my mental map for now I’m grinding on gazebo it works for ready made models but could be bulky for making newone I will check for jmavsim soon thank’s for your help

I’ve been trying to solve this exact problem for the past few days. I get the same error messages as proff.

I am running ubuntu 16.04.5 in a virtual box machine; win 7 pro is the host OS.

Although there appears to be a windows solution re, Windows Cygwin, there is still nothing similar to use with a VM environment running ubuntu. This situation has become a royal pain in the neck. I want to stay in a linux environment for my project, but I may be faced with moving to Windows to get something working.

I could use some help making PX4, QGC, MAVSim, and linux an integrated environment, so I can start simulating a drone controlled by a Python script.

Novices like me go down the path gluing together so many modules and software pieces expecting something to work, and it rarely seems to be that way.

Can any of the developers please fix this problem? I would surely appreciate it.

Forgive my rant. Its been a frustrating time trying to get the sim working.
