Building on Raspberry Pi 5

This guide covers building the wireless monitor tool on Raspberry Pi 5 running Raspberry Pi OS (Debian-based).

Prerequisites

Install Build Tools and Dependencies

# Update package list
sudo apt-get update

# Install build essentials and autotools
sudo apt-get install -y \
    build-essential \
    autoconf \
    automake \
    libtool \
    pkg-config

# Install WiFi monitoring libraries
sudo apt-get install -y \
    libpcap-dev \
    libnl-genl-3-dev \
    libnl-3-dev

Building

cd wireless-monitor-template

# Generate configure script
./autogen.sh

# Configure build
./configure

# Build
make

# Test (as root - required for monitor mode)
sudo ./src/wireless_monitor wlan0 11

Installation (Optional)

# Install system-wide
sudo make install

# Then run from anywhere
sudo wireless_monitor wlan0 11

Troubleshooting

Missing autotools

If autogen.sh fails:

sudo apt-get install autoconf automake libtool

Missing pkg-config

If configure fails to find libraries:

sudo apt-get install pkg-config

Library Not Found

If you get linker errors:

# Verify libraries are installed
pkg-config --exists libpcap && echo "libpcap OK" || echo "libpcap missing"
pkg-config --exists libnl-genl-3.0 && echo "libnl-genl OK" || echo "libnl-genl missing"
pkg-config --exists libnl-3.0 && echo "libnl-3 OK" || echo "libnl-3 missing"

Monitor Mode Permission Denied

Must run as root:

sudo ./src/wireless_monitor wlan0 11

Cross-Compilation (from Linux PC)

If you want to cross-compile from a Linux PC:

# Install cross-compiler
sudo apt-get install gcc-aarch64-linux-gnu

# Configure for cross-compilation
./autogen.sh
./configure --host=aarch64-linux-gnu \
    PKG_CONFIG_PATH=/usr/lib/aarch64-linux-gnu/pkgconfig

make
