Build error - cheribuild.py cheribsd-aarch64 -d

Hello,

When I try to build for aarch64, using the command 'cheribuild.py cheribsd-aarch64 -d', I get the following error in between and the build fails resulting in a fatal error as shown below:

I'm using VMware WorkStation 16.1.2 build-17966106, Ubuntu 20.04.5 LTS, and the latest build on Github(of cheribuild as on today)

Also, when I try "./cheribuild.py llvm-aarch64", I get the following error:
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
duser@172.16.0.157:~/Documents/Beam-connectivity/Project1/cheribuild$ ./cheribuild.py llvm-aarch64

Fatal error: Dependency for llvm-aarch64 missing: /home/duser/cheri/output/sdk/bin/clang version 0.0.0 is not supported. Clang version 3.8 or newer is required.
Possible solution: Run apt install clang
Alternatively if the repository version is too old, try running:
sudo apt install software-properties-common
sudo bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)"

Hello,

I could resolve the issue. I updated the OS to Ubuntu 22.04 and retried from scratch. It worked.

Thank you,

For the first error I don’t know what the issue is, the log excerpt you posted doesn’t contain an actual error, just the build tool reporting that there was an error when running the compiler (which itself should have reported the actual error).

For the second error you didn’t have a working CHERI LLVM built yet and didn’t pass -d, so LLVM could not be cross-compiled for aarch64 using it.
