Barrentenberg installation not working #8368

Closed hridambasu closed 2 months ago

hridambasu commented 2 months ago

When I am trying to install Barrentenberg on my MacOS Laptop by the following commands as mentioned in the README file:

  1. curl -L https://raw.githubusercontent.com/AztecProtocol/aztec-packages/master/barretenberg/cpp/installation/install | bash
  2. source ~/.zshrc
  3. bbup -v 0.46.1
  4. bb --version gives the following error:

Reinstalling LLVM via Homebrew solved this issue!

@hridambasu I reinstalled LLVM but no luck :/

This is my env

nargo version = 0.33.0
noirc version = 0.33.0+325dac54efb6f99201de9fdeb0a507d45189607d

2 solutions, either:

  1. install llvm@16 using homebrew. This will put the expected library in the place where it's looking
  2. tell the executable where to find the libunwind library:
    • make sure you can find the libunwind.1.dylib file as part of your llvm installation (llvm versions >12 should have it in a folder called lib/)
    • patch the executable using install_name_tool (it's built in macos, nothing to install): this link explains how.
