Troubleshooting Debian 12 Simple HTTP Server Installation: "pkg-config command not found"

This guide resolves the "pkg-config command not found" error encountered when installing Simple HTTP Server on Debian 12. This error arises because the Rust build process relies on pkg-config to locate and configure system libraries.

Solution:

The fix involves updating your system's package lists and installing the necessary packages:

1. Update Package Lists: Refresh your system's package index:

   sudo apt update

2. Install pkg-config: Install the pkg-config utility:

   sudo apt install pkg-config

3. Install Essential Development Libraries: Install libssl-dev, providing the SSL development files often needed for networking in Rust projects:

   sudo apt install libssl-dev

4. Re-attempt Simple HTTP Server Installation: Retry the installation command:

   cargo install simple-http-server

Further Troubleshooting:

If problems persist, try these additional steps:

1. Update Rust Toolchain: Ensure your Rust environment is current:

   rustup update

2. Install Build Essentials: Install essential build tools:

   sudo apt install build-essential

3. Manual SSL Library Path (If SSL Errors Remain): If SSL-related errors continue, explicitly set the OpenSSL directory path before reinstalling:

   export OPENSSL_DIR=/usr/lib/ssl
   cargo install simple-http-server

Explanation:

• pkg-config: A tool that provides metadata about installed libraries.
• libssl-dev: Contains files required for SSL support, crucial for HTTPS functionality in Simple HTTP Server.
• build-essential: A meta-package containing essential compilation tools for building software from source.

By installing these packages, you provide the necessary components for a successful Simple HTTP Server build and installation on your Debian 12 system. After completing these steps, the Simple HTTP Server should install correctly.
