Compiling Pixlie AI 0.1.2 on MacOS

The latest updates in our dependencies causes the compilation of Pixlie AI on MacOS to break, since it is not able to get access to some of the system dependencies.

To fix these issues, you need to take the following steps:

Install llvm using Homebrew, by running:
```
brew install llvm
```

Add the following lines at the bottom of the file ~/.zshrc:

export LIBCLANG_PATH=$(brew --prefix llvm)/lib
export DYLD_LIBRARY_PATH="$LIBCLANG_PATH:$DYLD_LIBRARY_PATH"
export PATH=$(brew --prefix llvm)/bin:$PATH

export CC=$(brew --prefix llvm)/bin/clang
export CXX=$(brew --prefix llvm)/bin/clang++

To quickly open the file using TextEdit from your terminal, you can run:

open -a "TextEdit" ~/.zshrc

Open a new terminal or reload the environment:
```
omz reload
```
Now try to run Pixlie AI while you’re in the pixlie_ai folder:
```
cargo run --bin cli
```

Update: 2 Mar, 2025

Some users have reported that the above steps are not enough and it still throws the error linking with `cc` failed.

If you’re facing this error after making the above changes, please make sure you are using a fresh/reloaded terminal environment and take the following steps:

Install rocksdb:
```
brew install rocksdb
```

Add the following lines at the bottom of the file ~/.zshrc:

export ROCKSDB_INCLUDE_DIR=$(brew --prefix rocksdb)/include
export ROCKSDB_LIB_DIR=$(brew --prefix rocksdb)/lib

Open a new terminal or reload the environment and try running Pixlie AI again.

Update: 4 Mar, 2025

The above steps still throw an error in rust-analyzer running in the VS Code IDE, affecting some development features.

To resolve these issues, you can do the following:

Install lld:
```
brew install lld
```
Run the following to check the installation path of Homebrew:
```
brew --prefix
```
If the base path is not the same in step (3) below, you can use the correct path in settings.json.

Add these settings to .vscode/settings.json in the project root:

{
    "rust-analyzer.runnables.extraEnv": {
        "LIBCLANG_PATH": "/opt/homebrew/opt/llvm/lib",
        "DYLD_LIBRARY_PATH": "/opt/homebrew/opt/llvm/lib",
        "PATH": "/opt/homebrew/opt/llvm/bin:${env:PATH}",

        "CC": "/opt/homebrew/opt/llvm/bin/clang",
        "CXX": "/opt/homebrew/opt/llvm/bin/clang++",
        
        "ROCKSDB_INCLUDE_DIR": "/opt/homebrew/opt/rocksdb/include",
        "ROCKSDB_LIB_DIR": "/opt/homebrew/opt/rocksdb/lib",
        
        "LD": "/opt/homebrew/opt/lld/bin/ld64.lld",
        "LDFLAGS": "-fuse-ld=/opt/homebrew/opt/lld/bin/ld64.lld",
        "AR": "/opt/homebrew/opt/llvm/bin/llvm-ar"
    }
}

You can exclude ROCKSDB_INCLUDE_DIR & ROCKSDB_LIB_DIR, if you have not installed rocksdb.

If you still face any issues with compiling Pixlie AI, please do not hesitate to contact us. We would love to hear from you – issue or no issue.

Pixlie is open source. And while we are still in the early phases, we will be finalizing this piece of the puzzle in the coming weeks. Try it out for your self and see what PixlieAI can do.
