[Request] Gazebo (one of ROS dependency)

[123-123-nil]

Link to the package(s) in the AUR

https://aur.archlinux.org/packages/gazebo

Utility this package has for you

I need ros-noetic-desktop-full for college. Gazebo is one of its dependency. I am unable to build gazebo as it requires a lot of ram(I was unable to perform a single threaded compile without -pipe flag with 16 GB of ram). Providing, this will make life of people who try to use ros-noetic or gazebo itself easier.

Do you consider the package(s) to be useful for every Chaotic-AUR user?

No, but for a few.

Do you consider the package to be useful for feature testing/preview?

• [ ] Yes

Have you tested if the package builds in a clean chroot?

• [ ] Yes

Does the package's license allow redistributing it?

YES!

Have you searched the issues to ensure this request is unique?

• [X] YES!

Have you read the README to ensure this package is not banned?

• [X] YES!

More information

The package seems to have issues with ffmpeg 5. So one will have to wait till its devs patches the package.https://github.com/osrf/gazebo/issues/3180

Try chaotic get -r gazebo, then chaotic mkd lastpackage packagebeforelastone and so on (repoctl downloads in reverse order). The dependencies are likely in AUR and need to be built before the actual package.

ogre-1.10 -> 1.12 doesn't build on arch. ignition rendering 6.0.1 builds with ogre-1.9. ignition-common needs to be build from git because of ffmpeg5, and gazebo also has to be build from git with unmerged PR for fixing ffmpeg5. Building gazebo required ~55GB of RAM.

[dr460nf1r3]

That explains why I had difficulties building this.. :/

[0ljik]

probably ros-noetic-gazebo-ros also requires 50GB RAM to build. This package is also required for connecting ROS with gazebo. I have built galactic version from git. CMakeFiles in test for gazebo_ros and gazebo_plugins required linking tbb library to successfully build.

[acxz]

ros-noetic-gazebo-ros does not require that much RAM, it's only gazebo which it depends on. Note, that the build RAM usage can be decreased by lowering the amount of cores used. However, that is currently not possible as ninja, the build used for gazebo, does not support reading from environment variables. A change to the PKGBUILD such as replacing ninja with ninja $NINJAFLAGS would be required.

Weird, in my experience yay has the best dependency resolution out of all the existing AUR helpers, including paru.

ogre-1.10 -> 1.12 doesn't build on arch.

gazebo does not work with ogre>1.9 only ogre=1.9.

ignition rendering 6.0.1 builds with ogre-1.9.

gazebo does not require ignition-rendering

ignition-common needs to be build from git because of ffmpeg5,

To be specific here, ignition-common-3 is required to build gazebo. ignition-common-3 does not require ffmpeg5 but it uses the older compat package ffmpeg4.4.

and gazebo also has to be build from git with unmerged PR for fixing ffmpeg5.

gazebo builds in a clean chroot just fine for me, without installing git or patching the package. If you could post a build/error log over at https://aur.archlinux.org/packages/gazebo, we could help you any issues you might be facing. (Maybe gazebo should add an explicit dep on ffmpeg4.4 instead of just using ffmepg).

sorry, I was mistaken for other package that required ignition-rendering

that's for you to decide which one do you want to use. I tend to go with arch version rather than old compat versions from aur. I don't have any issues. All I wanted to was to give information what I had. I am already running sims and full ROS system with all dependencies for my project.

unless you are modifying the PKGBUILD, the deps will be pulled in automatically which specifically state ffmpeg4.4

Saying that it needs to be built from git because of ffmpeg5 is an incorrect statement. The package does not need any modifications to be built on Chaotic-AUR and this FR shouldn't be held up because of that.

I tend to go with arch version rather than old compat versions from aur.

I assume by arch version you mean the packages available in the official repos. ([core]/[extra]/[community]). ffmpeg4.4 is also available in [extra] and is not in the aur.

Supposedly the issue was fixed in https://github.com/osrf/gazebo/pull/3195

[xiota]

gazebo and related packages are broken and look complicated to fix. Metrics show 0 downloads. I plan to drop if there are no objections.

[xiota]

Dependencies are also dropped. If any are still needed, feel free to open new requests.
