Barrentenberg installation not working

[hridambasu]

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:

dyld[48923]: Library not loaded: /usr/local/opt/llvm@16/lib/libunwind.1.dylib

My nargo version:
nargo version = 0.32.0
noirc version = 0.32.0+c679f01a19b02ad2ac2287c8e699b46887f7872c

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.
