Package 'clang-8' has no installation candidate, Ubuntu 22.04 #4892

Some problem!!! |
|
I installed clang-11 and changed it in setup.sh, but build.sh failed to find -lc++fs: no file or directory |
|
facing the same issue, has someone found the solution? It looks like clang-8 is not supported in Ubuntu 22.04. @chenfei8888 did you figure out the solution? |
|
According to this SO post it seems like the C/C++ filesystem library was added to the base standard library in later releases so removing them should suffice. Changes to remove them here: Seems to build successfully, haven't tested anything as of yet. |
|
I installed it with clang-12 here is what I have changed within the files. Im using it with Unity
setup.sh build.sh cmake/cmake-modules/CommonSetup.cmake ros2/src/airsim_ros_pks/CMakeLists.txt Unity/build.sh |
I got following errors, -lstdc++ No such file or directory |
I ended up using ubuntu20.04. |
Just in case anyone else arrives here via google. Run the following in terminal and then re-run build.sh: sudo apt-get -y install libunwind-dev libstdc++-12-dev Should work now. Happy to create a PR for @JulianDev24 + my changes if repo maintainers are interested? |
The maintainers were unfortunately laid off. Initially, microsoft announced they were deprecated this repo for a newer, "Project Airsim" (probably an internal reorg). In October 2023, https://wonderfulengineering.com/microsoft-just-shut-down-its-industrial-metaverse-project-airsim-and-laid-off-its-team/
I wonder if someone should/could fork it, maybe that person could be me in many months time - just getting started with Airsim right now 😂️ Getting AirSim building in early 2024Warning: After getting Airsim to build, I couldn't open the Blocks unreal project in Unreal 4.27:
I use Debian 12 (admittedly, not ubuntu 22.04), and had to use LLVM/clang18 and remove usage of diff --git a/Unity/build.sh b/Unity/build.sh

@xxEoD2242, your repo has the same issues since it still uses clang 8 and references old libraries like |
|
@ben-xD We don't support Ubuntu 22.04 natively. You need to update the clang and vulkan libraries if you want to install it locally. Or use Docker |

We're struggling with a similar issue on our sim. Changing clang version from 8 → 12 breaks compatibility on Ubuntu 20.04, because of pthread symbols that are exposed in the rpclib library that are undefined for the cross-compile tool for Unreal Engine 4.27. Apparently this PR fixes the issues on Ubuntu 22.04. We do however use an older version of Airsim that was stripped down a lot. @xxEoD2242 Do you see a similar issue when changing from clang version 8 → 12 when using UE 5+? The symbol I'm talking about is |
it works for me! |
|
Similar to @ben-xD adding that I was also able to get this to work on Ubuntu 24.04.1 by replacing references to clang-8 with clang-18 (the version of clang you get with In other interesting news, the LinuxBlocks 1.8.1 binary works again -- I guess they got Vulkan figured out. Woo! |
@nabeelsherazi Were you able to open the Blocks unreal project in Unreal 4.27? (just like it was mentioned in a comment of @ben-xD) |
Uh oh!
There was an error while loading. Please reload this page.
Bug report
What's the issue you encountered?
I follow the instruction: https://microsoft.github.io/AirSim/build_linux/ to install AirSim in Ubuntu
In a section "Build AirSim" I cloned repository and then executed
./setup.shThis provoke an error: "Package 'clang-8' has no installation candidate"
I did not find any similar issue or any relative information. The full log is shown below. Please help if you have any idea how to fix it. I saw that clang is not supported for Ubuntu 22.04, but maybe there is a way to run it without reinstalling Ubuntu.

How can the issue be reproduced?
