Colcon build of Gazebo Garden version error #66

Closed ConnorDTaylor closed 1 year ago

ConnorDTaylor commented 1 year ago

Hi Rhys,

I have started up a VM in Ubuntu 20.04 to try and get Gazebo Garden working with ROS2 and this simulation. I got Gazebo Garden installed properly, however when I add asv_sim to the workspace which Garden in it, the package will not build and gives me the following errors.

/home/connort/gazebo_garden/src/asv_wave_sim/gz-waves/src/SubMeshWithTangents.cc:60:1: error: function ‘gz::common::SubMeshWithTangents::SubMeshWithTangents(gz::common::SubMeshWithTangents&&)’ defaulted on its redeclaration with an exception-specification that differs from the implicit exception-specification ‘’

What would be the reason for this error?

I think this problem may have something to do with GCC being used to compile the code instead of Clang++. It seems the noexpect = default is the culprit, I'm trying to figure out if there is a work around to this problem which isn't changing my compiler.

srmainwaring commented 1 year ago

I did my test build on Ubuntu 22.04 and it seems there are a couple of compiler / library differences.

Here are the fixes for Ubuntu 20.04 with Gazebo Garden built from source:

  1. SubMeshWithTangents

Comment the move copy constructor and assignment operators (the ones with noexcept) in the header and source file. Related to this SO question: https://stackoverflow.com/questions/47032077/noexcept-default-compilation-error

  1. TriangulatedGrid around L79. This is because Ubuntu 20.04 uses CGAL libcgal-dev/focal,now 5.0.2-3 and macOS / Ubuntui 22.04 are using CGAL 5.4 or later.
- typedef CGAL::No_constrain_intersection_tag                    Itag;
+ typedef CGAL::No_intersection_tag                                     Itag;

Btw: I tried using the nightly builds of gz-garden: https://classic.gazebosim.org/tutorials?tut=install_unstable&cat=install

sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-nightly `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-nightly.list'
wget https://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -
sudo apt-get update
sudo apt-get install gz-garden

These install and run on Ubuntu 20.04 but unfortunately are no good for developing against as the library dependencies are not supported (I hit issues with protobuf inconsistencies when building asv_wave_sim). So building gz-garden from source is your only option unless you upgrade.

ConnorDTaylor commented 1 year ago

Hi Rhys,

I now have the package working, but im running into a new issue which may also be caused by using Ubuntu 20.04 or it is cause by my using a VM. I should note I had to change the the default version of ogre3D (ogre2) to ogre (AKA ogre1.1) because of the VM I am using. There errors I am getting are:

[Err] [SystemLoader.cc:87] Failed to load system plugin [gz-waves1-waves-model-system] : couldn't find shared library. [Err] [SystemLoader.cc:87] Failed to load system plugin [gz-waves1-waves-visual-system] : couldn't find shared library.

Which indicate to me that the plugins aren't being found, but I'm not sure how or where to point them. I have a feeling that these errors might be related to the switch in ogre version, in which case I will need to try to figure out a way to install ogre2 in my VM. However, I figured I would run this error by you in the mean time in case it is caused by something else. Gazebo Garden is a big shift from Gazebo9 so I don't know what I don't know.

srmainwaring commented 1 year ago

Yes, the errors are because you are using ogre1 and the plugins require ogre2.

You can install the dependencies for Gazebo using the instructions here: https://gazebosim.org/docs/garden/install_ubuntu_src

This is the command given in the help for installing the dependencies on Ubuntu:

sudo apt -y install \
  $(sort -u $(find . -iname 'packages-'`lsb_release -cs`'.apt' -o -iname 'packages.apt' | grep -v '/\.git/') | sed '/gz\|sdf/d' | tr '\n' ' ')

You'll then need to rebuild gz-rendering, gz-gui7, gz-sensors7 and gz-sim7.

Does the rendering work running ogre2 on your VM? The reason I ask is that on a macOS host running VM fusion you cannot use hardware acceleration on the VM because the drivers do not support OpenGL 4.2+. You can use llvmpipe, but it's practically unusable for the waves simulation (good for checking it runs, but that's about it). The latter option only works on Ubuntu 22.04 because it needs a later version of mesa utils.

ConnorDTaylor commented 1 year ago

I’ll try Ilvmpipe tomorrow when I get back into my lab, I was reading about it but I wasn’t sure if it would work. If I had my computer environment booted in 20.04 would the simulator work with ogre2? Or are you saying ogre2 is only available in Ubuntu 22.04? I am stuck using 20.04 due to my reliance on PX4 and i’m thinking about using this wave simulator with ROS2 for my SITL simulations.

I appreciate your help Rhys, thanks a ton.

srmainwaring commented 1 year ago

You can install ogre2 on Ubuntu 20.04, it's more a question of whether anything using the ogre2 render engine will display on an Ubuntu 20.04 VM. In my case even the basic shapes.sdf world does not render on an Ubuntu 20.04 VM (with either a hardware accelerated or llvmpipe driver).

The situation for an Ubuntu 22.04 VM is similar except that you will get something to render if you run the simulator using

LIBGL_ALWAYS_SOFTWARE=1 gz sim -v4 waves.sdf

but it will be very slow - unusably slow.

Your best option is to run the simulation natively on either an Ubuntu machine or (macOS if you have the patience to set up the dev environment - it runs on both Intel and arm64 macs now). You could still spin up most of the ROS2 nodes on the VM if you have the network shared. The ros_gz_bridge node will need to run on the host machine though as it needs access to the gz-transport layer.

Hi Rhys,

I have moved my environment to 22.04 and upon installing gazebo from binaries on the website I am still getting the following errors:

[Err] [SystemLoader.cc:87] Failed to load system plugin [gz-waves1-waves-model-system] : couldn't find shared library.

I figure the binary install grabs the required dependencies, so it it possible that the files arent being sourced properly?

srmainwaring commented 1 year ago

This looks like a path issue. You need to set GZ_SIM_SYSTEM_PLUGIN_PATH to the location of the plugin library for custom plugins (looks like I missed that out in the instructions). Try

export GZ_SIM_SYSTEM_PLUGIN_PATH=~/gz_waves_ws/install/lib

(or similar according to your workspace location).

The ArduPilotPlugin won't be found unless you have built it. The WAM-V model references that - but will still float if it's not available.

ConnorDTaylor commented 1 year ago

I had to add the path as: export GZ_SIM_SYSTEM_PLUGIN_PATH=\ $HOME/colcon_ws/install/gz-waves1/lib

Because the form you sent simply gave the same error as before. However, I am now getting this permission error:

Error while loading the library [/home/connor/colcon_ws/install/gz-waves1/lib/libgz-waves1-waves-model-system.so]: libgz-waves1.so.1: cannot open shared object file: No such file or directory [Err] [SystemLoader.cc:104] Failed to load system plugin [gz-waves1-waves-model-system] : couldn't load library on path [/home/connor/colcon_ws/install/gz-waves1/lib/libgz-waves1-waves-model-system.so].

srmainwaring commented 1 year ago

I see, it looks like you have used the default build rather than --merge-install. It should not make too much difference if the environment variables are set up correctly. It still looks like a path issue though. Can you see all the plugin libraries in the folder $HOME/colcon_ws/install/gz-waves1/lib? I'm assuming you have run source ./install/setup.bash. Could you post the results of 

printenv | grep GZ

which may provide some more info on what's going on with your paths.

ConnorDTaylor commented 1 year ago

Hi Rhys,

Im getting used to this new Gazebo and forgot to source setup.bash, I am used to only doing that when running ROS files. Sorry about that! It seems the simulation is working now.

I am seeing that the waves and items in the water keep flashing in and out of the simulator and the waves are acting sort of buggy. Have you encountered this? I am not sure if there is a way I could send a video of the environment to show clearly what I mean.

srmainwaring commented 1 year ago

Great, it's running! I don't see rendering artefacts on my side, but this could be video card settings or something similar? You can record short mp4 files and post them in the issue (10MB or less).

ConnorDTaylor commented 1 year ago

Hopefully, you can see this. I am wondering if it is a graphics card issue.

srmainwaring commented 1 year ago

You're not running two instances of the server by any chance? On macOS you need to run the client and server separately as the OS does not let ruby fork the process. On linux you can run both from the one terminal (my instructions say to run them separately because it will work on both platforms. However if you forget the -g or -s flags then you can wind up with two servers for one gui and that may cause the effect you are seeing.

ConnorDTaylor commented 1 year ago

I am running the server and client in two different terminals, as per the instructions. I also noticed that the simulation is continuously pausing the playing, but I can rotate the simulation and move the camera around with little issue so im not so sure it is a computer hardware problem.

srmainwaring commented 1 year ago

Hmm, very strange. Try killing all the gz sim processes then run both client and sever in one terminal:

gz sim -v4 waves.sdf

Any difference?

The waves are rendering fine - so I don't think its an OpenGL version issue. It could be system resources but we'll need more info to determine that (or try a different wave generator that uses less RAM and CPU).

ConnorDTaylor commented 1 year ago

No difference, though now the objects in the water aren't loading strangely. I did notice I get this message in the terminal though. Also I changed from the fft algorithm to the trochoid algorithm. Since that was the same as the one in the Gazebo9 sim which I could run fine.

[/sdf/plugin[@name="gz::sim::systems::WavesVisual"]::L1]: XML Element[plugin], child of element[sdf], not defined in SDF. Copying[plugin] as children of [sdf].

srmainwaring commented 1 year ago

I don't think the warning is causing the problem - I'm seeing a similar message on the latest Gazebo build. Tracing the issue may take some work. Below is the bug report template for gz-sim. I don't need all explanation, but the system details will help, as will a print of the environment and any ogre logs.

As previously mentioned, the issue is the models in the simulation flicker in and out. The simulation also repeatedly pauses and starts.

srmainwaring commented 1 year ago

@ConnorDTaylor I can't see anything obvious that might cause the issue you're seeing. Your graphics card has 4GB RAM which should be fine. I can't see how many cores and what RAM you PC has: it may be CPU or RAM bound?

Have you tried running any of the Gazebo examples (there are a number in gz-sim/examples/worlds). Some of them are graphics / CPU intensive (for example the ones testing sensors). At the moment it's difficult to tell if it's a problem with my plugins in particular or something else in your set up.

One other thing to try is exporting GZ_IP=127.0.0.1, it could be a transport issue with the client lagging because pose updates from the server are taking too long - although I'm just speculating.

ConnorDTaylor commented 1 year ago

So I tried he GZ_IP, which didnt seem to make much difference however when trying to simualtion today I am getting these warnings which I think is in reference to the objects in the water: [GUI] [Wrn] [Component.hh:144] Trying to serialize component with data type [St6vectorIdSaIdEE], which doesn't have operator<<.

I also got rid of the in water objects for the time being in the waves.sdf file but they still appear in the entity tree.

I have also just tried using other SDF files, however whenever I try to open a different SDF file it opens just the waves.sdf file for some reason. Maybe this is a GZ Path issue?

ConnorDTaylor commented 1 year ago

UPDATE: I am still getting the warnings detailed above, however after noticing the wave sim kept reverting back to the waves.sdf I thought the computer may have been having some sort of memory problem. So I restarted and now the wave sim seems to be working smoothly! I will let you know if any other issues arise but I think it is working as of now.
