Quick Start

Prerequisites

• macOS or Linux system
• Homebrew installed
• Bash shell

Installation

1. Clone this repository:

git clone https://github.com/aboubakr-jelloulat/readline-brew-installer.git
cd readline-brew-installer

2. Make the script executable:

chmod +x install_readline.sh

3. Run the installation script:

./install_readline.sh

📋 What the Script Does

1. Installs readline using Homebrew
2. Links the library with force flag to ensure proper linking
3. Detects installation path automatically
4. Sets environment variables for compilation
5. Reloads shell configuration to apply changes immediately

🔧 Manual Configuration

If you need to manually set the paths, update these environment variables in your shell configuration file (.zshrc, .bashrc, etc.):

export LDFLAGS="-L/path/to/readline/lib"
export CPPFLAGS="-I/path/to/readline/include"

🛠️ Troubleshooting

Common Issues

• Permission denied: Make sure the script is executable (chmod +x install_readline.sh)
• Homebrew not found: Install Homebrew first from brew.sh
• Path issues: Verify your readline installation path with brew --prefix readline

Verify Installation

Check if readline is properly installed:

brew list | grep readline
pkg-config --libs readline
