Package 'clang-8' has no installation candidate, Ubuntu 22.04
Bug report
- AirSim Version/#commit: 1.8.1
- UE/Unity version: 4.27
- autopilot version: ArduPilot 4.4.1
- OS Version: Ubuntu 22.04.3
- python 3.9.17
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.sh
This 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.
Settings
How can the issue be reproduced?
- Just follow the AirSim installation procedure from https://microsoft.github.io/AirSim/build_linux/

### Tasks
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: https://github.com/Kanaderu/AirSim/commit/ac76e3908a768cc6e6fada54b77897695f48bcb7
Seems to build successfully, haven't tested anything as of yet.

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.

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/
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 2024
Warning: 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 -lc++fs since that is no longer necessary. Apply these changes:

if ! which cmake; then
@xxEoD2242, your repo has the same issues since it still uses clang 8 and references old libraries like vulkan-utils? See https://github.com/CodexLabsLLC/Colosseum/blob/2383b0adfc674d34e68cb05ef163ca1c00479352/setup.sh#L53 and https://github.com/CodexLabsLLC/Colosseum/blob/2383b0adfc674d34e68cb05ef163ca1c00479352/setup.sh#L63
@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 pthread_cond_clockwait which is available since glibc 2.30, while the crosscompile toolchain for UE 4.27 uses glibc v2.17.
I installed it with clang-12 here is what I have changed within the files. Im using it with Unity

it works for me! thx!
