Anubis Windows Commands

Anubis Windows Commands

Problem

When running Claude Code on Windows in Git Bash (MSYS/MinGW environment), the shell automatically converts paths starting with // to /. This breaks Anubis target paths like //mode:win_dev or //examples/simple_cpp:simple_cpp.

Example of the problem:

# What you type:
cargo run --release -- build -m //mode:win_dev -t //examples/simple_cpp:simple_cpp

# What Git Bash sends to the command:
cargo run --release -- build -m /mode:win_dev -t /examples/simple_cpp:simple_cpp

This causes Anubis to fail because it expects target paths to start with //.

Solution

Use the MSYS_NO_PATHCONV=1 environment variable prefix to disable Git Bash path conversion.

Required Command Format

For cargo run commands:

MSYS_NO_PATHCONV=1 cargo run --release -- build -m //mode:win_dev -t //examples/simple_cpp:simple_cpp

For anubis.exe directly:

MSYS_NO_PATHCONV=1 ./target/release/anubis.exe build -m //mode:win_dev -t //examples/simple_cpp:simple_cpp

For multi-target builds:

MSYS_NO_PATHCONV=1 cargo run --release -- build --workers 16 -l debug --mode //mode:win_release --targets //examples/nested_staticlib_cpp/...

When to Apply This Fix

Apply MSYS_NO_PATHCONV=1 when ALL of these conditions are true:

1. Platform is Windows (host_platform is windows)
2. Shell is Git Bash (MSYS/MinGW environment - check for MSYSTEM env var or /usr/bin/bash path)
3. Command contains // paths (Anubis target notation)

Detection

To detect if you're in Git Bash on Windows:

# Check if MSYSTEM is set (Git Bash sets this)
echo $MSYSTEM

# Or check the shell path
echo $SHELL

If MSYSTEM is set to MINGW64, MINGW32, or MSYS, you're in Git Bash and need the prefix.

Command Templates

Build a single target (Windows dev mode):

MSYS_NO_PATHCONV=1 cargo run --release -- build -m //mode:win_dev -t //examples/simple_cpp:simple_cpp

Build a single target (Windows release mode):

MSYS_NO_PATHCONV=1 cargo run --release -- build -m //mode:win_release -t //examples/simple_cpp:simple_cpp

Build a single target (Linux cross-compile):

MSYS_NO_PATHCONV=1 cargo run --release -- build -m //mode:linux_dev -t //examples/simple_cpp:simple_cpp

Build all targets in a directory (recursive):

MSYS_NO_PATHCONV=1 cargo run --release -- build -m //mode:win_dev -t //examples/...

Build with debug logging:

MSYS_NO_PATHCONV=1 cargo run --release -- build -l debug -m //mode:win_dev -t //examples/simple_cpp:simple_cpp

Build with trace logging and custom worker count:

MSYS_NO_PATHCONV=1 cargo run --release -- build --workers 16 -l trace -m //mode:win_dev -t //examples/simple_cpp:simple_cpp

Build multiple specific targets:

MSYS_NO_PATHCONV=1 cargo run --release -- build -m //mode:win_dev -t //examples/simple_cpp:simple_cpp -t //examples/trivial_cpp:trivial_cpp

Common Anubis Commands Reference

Notes

• The MSYS_NO_PATHCONV=1 prefix is harmless on non-Windows systems or non-Git-Bash shells, but it's only necessary in Git Bash on Windows.
• This only affects commands with // path arguments. Standard cargo commands like cargo build or cargo test don't need the prefix.
• The prefix must come before the command, not after.

Troubleshooting

If you see errors like:

• Error: Failed to parse target path '/mode:win_dev'
• Error: Target path must start with '//'
• Error: Invalid target specification

These indicate Git Bash path conversion is occurring. Add the MSYS_NO_PATHCONV=1 prefix.
