Transpiler fails to build under Ubuntu 22.04 about fully-homomorphic-encryption HOT 4 CLOSED

Acknowledged. I'm going to get the existing Debian docker image working again and then modify it for Ubuntu 22.04.

As a preview, I'm modifying the Dockerfile to install LLVM inside the image via apt, and then trying to ensure the LLVM version 13 aligns with the installed version, so that one is not required to rebuild LLVM from scratch.

RUN wget -O llvm.sh https://apt.llvm.org/llvm.sh \
  && chmod +x llvm.sh \
  # It's critical that this version matches the version specified in
  # llvm_toolchain in the WORKSPACE file.
  && ./llvm.sh 13

LLVM has an Ubuntu 22.04 package, but the WORKSPACE file is currently pinning to LLVM 10, and the 22.04 versions start at 11, while 10 is only supported for 18.04 and 20.04. Because we rely on XLS for the hardware synthesis toolchain XLS, and they use LLVM 13, I'm going to try to make it all work with LLVM 13.

In other words, you may be able to fix this quickly by changing the llvm_toolchain version in WORKSPACE to match the LLVM installed on your machine, and use the command above to install the version of your choice.

A patch has been submitted to add an Ubuntu jammy dockerfile. Probably won't get reviewed internally until next week as folks are out of office. In the mean time, 23491cc should resolve your installation issues by switching the project to use LLVM 13, which has a package on jammy.

To install LLVM manually on your machine, you can run

wget -O llvm.sh https://apt.llvm.org/llvm.sh \
  && chmod +x llvm.sh \
  # It's critical that this version matches the version specified in
  # llvm_toolchain in the WORKSPACE file.
  && ./llvm.sh 13
