And every time I run this command (Tools/environment_install/install-prereqs-ubuntu.sh -y
) Will look like the picture, I’m not sure if this is normal, I need to exit with ctrl+z.
That is not a compile error.
After the compilation, compiled SITL binary and MAVProxy is automatically started with sim_vehicle.py.
when you type mavproxy.py on the terminal and press enter, do you see an error message related with the terrain? Or in the MAVProxy terminal, module load terrain? You can start the SITL on its own, without sim_vehicle.py an then connect to it with mavproxy.py. I made a tutorial here.
After I ran the command (./sim_vehicle.py -v ArduCopter --map --console) in the /ardupilot/Tools/autotest/ directory, a window flashed and then closed. That window should be a mavproxy window.
Do python3 -m pip install --upgrade mavproxy
and also python -m pip install --upgrade mavproxy
If it is still not working, you can try fresh installing the environment again.
Follow here and then here.
It should work.
Question are you using the install script as it was from the 4.07 release?
I looked for this output, dpkg-query -l "lsb-release, from your install_script console and it appears in 4.07 but not in 4.2Dev
The 4.07 install script might not work correctly anymore… a lot has changed since in terms of environment and Ubuntu 20.04 wasn’t around then??
Clone your fork of master
use the install_script from 4.2Dev
Check that sitl works on 4.2Dev (if you need to build a board check that works too on master)
I use the command (git checkout Copter-4.0.7) to switch the version to 4.0.7.
I changed the version of ubuntu to 18.04, but the same problem still occurs. After I copied the code that can run on other virtual machines, the same problem still occurred.
I would like to ask whether the installation of ArduPilot uses python3 or python2. I have been using python3 in the environment.
I need to use 4.0.7 to reproduce some work related to the thesis.
You didn’t answer the first question regarding the install script? There are of course other updates that change in those install scripts besides OS as time moves forward.
Did you do any of the steps I suggested?
Please put into a text file the full output from ./waf configure --board=CubeOrange & ./waf copter
I will of course defer to Amilcar on pyhton2 vs 3.
I can easily build 4.07 on my WSL machine with Ubuntu 20.04 for sitl. A real board requires some “intervention” unfortunately…
Couple caveats. And a better dev than I will probably have an easier way to do this…
In the current dev version move out the file Tools/gittools/submodule_sync.sh
you will need that to fix your submodules. And it wont exist when you checkout 4.07
In the ardupilot directory run submodule_sync.sh script
Build for sitl that should work, ./Tools/autotest/sim_vehicle.py -v Plane --console -D --speedup 1 --map
Everything below assumes you want to build for an actual board else you dont need to do these
4. You will need to switch to using the arm compilers (g++ 6.3) from that time as the defaults now install (g++ 10)
You will thus need to install arm_6.3 compilers: find them here
Right now I do this by modifying my path to the following export PATH="/opt/gcc-arm-none-eabi-6-2017-q2-update/bin:$PATH"
And I remove the /opt/gcc-arm-none-eabi-6-2017-q2-update/bin
You should be able to use waf --tool-chain option but that isnt working for me.
If you get permission errors when from make_intel_hex.py do a chmod -R 755 . assuming you are in the ardupilot directory
I am not sure whether the installation script will change after I use git to change the version of arducopter to 4.0.7, so I am not very sure whether I am using the 4.0.7 installation script.
I changed the installed version to 4.1.0. I ran ./waf configure --board=CubeOrange & ./waf copter and got the following output.

The previous error may be because I tried to install mavproxy in python3.8 and then run ardupilot. After I changed python to 2.7, I copied the ardupilot4.0.7 code that can run on another virtual machine to this new virtual machine and ran into this problem.
Yes, when you change the branch from master to 4.07 every file changes to be in the state the repository was at for the 4.07 branch. Thus this include the development environment scripts.
Ok. Please focus on one issue and lets work on that one.
From the screenshot of your desktop it is clear mavproxy did not start. “An exception has occurred from mavproxy.py …”
The first thing to do is getting everything working on master.
I have installed my ardupilot, I think the possible reasons for the problem are:
The python version may use python3 before, and the correct one should be python2.
pip install MAVProxy should pay attention to the case of letters, I am not sure if this is the cause of the error, but after I changed it, it ran successfully.
Some commands cannot be executed completely due to network reasons.
