Orca Slicer for Craftbot iOS MAC ‘libzstd’ fix

During the Orca Slicer for Craftbot iOS MAC installation the ZSTD library is missing.
You can add this missing library to your system ins a safe way.

Open a termina land type: ‘brew install zstd‘

If you do not have ‘brew’ Homebrew installed here is how you can install it

Installing Homebrew on a Mac is a straightforward process that involves running a single command in the Terminal. Here’s a step-by-step guide to get you set up.

Step 1: Install Xcode Command Line Tools

Before you can install Homebrew, you need to have Apple’s Command Line Tools installed. This package provides essential software development tools.

  1. Open the Terminal app. You can find it in your Applications folder, inside the Utilities folder, or by searching for it with Spotlight (⌘ + Space).
  2. Run the following command in the Terminal and press Enter:Bashxcode-select --install
  3. A software update window will pop up. Click “Install” and agree to the terms and conditions to complete the installation.

Step 2: Run the Homebrew Installation Script

With the Command Line Tools installed, you can now install Homebrew.

  1. Keep your Terminal window open.
  2. Copy and paste the following command into the Terminal and press Enter. This command downloads and runs the official Homebrew installation script.Bash/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  3. The script will explain what it’s going to install and will pause to ask for your confirmation. Press Enter to continue.
  4. You will be prompted to enter your Mac’s user password. Type it in and press Enter. Note that you won’t see the cursor move as you type; this is a security feature.

The installation will take a few minutes as it downloads and sets up all the necessary files.

Step 3: Add Homebrew to Your PATH (For Apple Silicon Macs)

If you have a newer Mac with an Apple Silicon chip (M1, M2, etc.), there’s one final step to ensure Homebrew commands work correctly. The installer will prompt you with the exact commands you need to run.

  1. After the installation is complete, the Terminal will display a “Next steps” section.
  2. You’ll need to run two commands to add Homebrew to your shell’s configuration file. Copy each command one at a time, paste it into the Terminal, and press Enter. They will look something like this:Bashecho 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
    andBasheval "$(/opt/homebrew/bin/brew shellenv)"

Step 4: Verify the Installation

To make sure everything is working correctly, close and reopen your Terminal window, then type the following command:

Bash

brew doctor

If the installation was successful, you should see the message: “Your system is ready to brew.” You’re now all set to start using Homebrew to install software!

​

And the FIX:

brew install zstd

​

Here’s a breakdown of what the command does:

  • brew: This is the command-line name for Homebrew, which is a very popular package manager for macOS. Think of it as an App Store for command-line software and other developer tools that Apple doesn’t include with the operating system. If you don’t have Homebrew installed, this command won’t work.
  • install: This is a subcommand for Homebrew that tells it you want to install a new piece of software.
  • zstd: This is the name of the package you want to install. In this case, it’s the Zstandard compression tool, a fast and efficient data compression library.

In short, the command instructs Homebrew to download, compile (if necessary), and install the Zstandard software on your Mac, making it available for other applications or for you to use in the terminal.
