Issue while Compiling Node for macOS

nakul1010 commented 1 year ago

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:

Install Rust

Execute the following command in the terminal to install Rust:
```
curl <https://sh.rustup.rs> -sSf | sh
```
Install OpenSSL

Install OpenSSL by running the following command:
```
brew install openssl
```
Update Current Shell

Update the current shell by executing the following command:
```
source ~/.cargo/env
```
Install Cmake
```
brew install cmake
```
Install Clang via OpenSSL (not brew)

Install Clang by running the command:
```
xcode-select --install
```

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

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

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...
