Issue while Compiling Node for macOS

[nakul1010]

Problem

Compiling the InterBtc repository on macOS requires specific dependencies to be installed correctly. The readme file provides multiple options for obtaining these dependencies. However, it is essential to follow the recommended steps in the correct order, especially for first-time macOS node compilation.

Solution

Follow the steps below to compile the InterBtc node on macOS:

1. Install Rust

   Execute the following command in the terminal to install Rust:

   curl <https://sh.rustup.rs> -sSf | sh
   
   

2. Install OpenSSL

   Install OpenSSL by running the following command:

   brew install openssl
   
   

3. Update Current Shell

   Update the current shell by executing the following command:

   source ~/.cargo/env
   
   

4. Install Cmake

   brew install cmake
   

5. Install Clang via OpenSSL (not brew)

   Install Clang by running the command:

   xcode-select --install
   
   

6. Verify Correct Paths

   Ensure that the following paths are correct:

   which llvm-ar
   /opt/homebrew/opt/llvm/bin/llvm-ar
   
   which clang
   /opt/homebrew/opt/llvm/bin/clang
   
   

7. Check GCC Version

   Verify that the GCC version is greater than 10:

   gcc --version
   Apple clang version 14.0.0 (clang-1400.0.29.202)
   Target: arm64-apple-darwin22.2.0
   Thread model: posix
   InstalledDir: /Library/Developer/CommandLineTools/usr/bin
   
   

8. Run Cargo Commands and Link LLVM and Clang

   Execute the following commands to build and link LLVM and Clang:

   cargo clean
   
   AR=/opt/homebrew/opt/llvm/bin/llvm-ar CC=/opt/homebrew/opt/llvm/bin/clang cargo build
   
   

Important Consideration

• Do not include any empty spaces between paths, as it may cause Jemalloc to panic. :)

By following these steps carefully, you should be able to successfully compile the InterBtc node on macOS.

On a new mac, it's also required to install llvm brew install llvm.

fixed by

1 Install llvm via homebrew, brew install llvm
2 Add the LLVM to your path PATH="/opt/homebrew/opt/llvm/bin:$PATH" (could be in your profile, .zshrc or equivalent)
3 Ensure you have the AR and CLANG environment vars exported, CC=/opt/homebrew/opt/llvm/bin/clang & AR=/opt/homebrew/opt/llvm/bin/llvm-ar
4 Run your command and hope for the best...
