Building AVRDUDE for macOS

Prerequisites

On macOS, you can normally install AVRDUDE through MacPorts (port install avrdude) or Homebrew (brew install avrdude).

The following things are needed to build AVRDUDE on MacOS:

• A C compiler; either full XCode, or the XCode Command Line tools
• cmake, pkg-config, hidapi, libftdi1, libusb, libelf, libserialport (libserialport is not available with MacPorts, so you have to build from source)

(note: alternative to pkg-config is pkgconf, both should work but you can install one of them).

Minimum required version for CMake is 3.14.

The following two build systems are supported.

1. Homebrew
2. MacPorts

Build Instructions without GNU Readline (using macOS bundled libedit) -- recommended

To build AVRDUDE for macOS using MacPorts, run the following commands:

port install cmake pkg-config hidapi libftdi1 libusb libusb-compat libelf libserialport
git clone https://github.com/avrdudes/avrdude.git
cd avrdude
./build.sh

To build AVRDUDE for macOS using Homebrew for macOS Intel or macOS Apple Silicon, run the following commands:

brew install cmake pkg-config hidapi libftdi libusb libusb-compat libelf libserialport
git clone https://github.com/avrdudes/avrdude.git
cd avrdude
./build.sh

Build Instructions with GNU Readline

macOS ships libedit which is a replacement of GNU Readline. As of Dec 2022, with the various fixes in place, libedit is considered as good enough for macOS for the purpose of avrdude, GNU Readline is not required.

In case you still prefer to use GNU Readline, you can follow the instructions below.

Homebrew:

brew install cmake hidapi libftdi libusb libusb-compat libelf readline libserialport
git clone https://github.com/avrdudes/avrdude.git
cd avrdude
(for macOS Intel)
cmake -D CMAKE_C_FLAGS=-I/usr/local/include -D CMAKE_EXE_LINKER_FLAGS=-L/usr/local/Cellar -D HAVE_LIBREADLINE:FILEPATH=/usr/local/opt/readline/lib/libreadline.dylib -D CMAKE_BUILD_TYPE=RelWithDebInfo -B build_darwin
(for macOS Apple Silicon) 
cmake -D CMAKE_C_FLAGS=-I/opt/homebrew/include -D CMAKE_EXE_LINKER_FLAGS=-L/opt/homebrew/Cellar -D HAVE_LIBREADLINE:FILEPATH=/opt/homebrew/opt/readline/lib/libreadline.dylib -D CMAKE_BUILD_TYPE=RelWithDebInfo -B build_darwin
cmake --build build_darwin

MacPorts:

port install cmake hidapi libftdi1 libusb libusb-compat libelf readline libserialport
git clone https://github.com/avrdudes/avrdude.git
cd avrdude
cmake -D CMAKE_C_FLAGS=-I/opt/local/include -D CMAKE_EXE_LINKER_FLAGS=-L/opt/local/lib -D CMAKE_BUILD_TYPE=RelWithDebInfo -B build_darwin
cmake --build build_darwin

Installation for MacPorts

To install a local build on your system for MacPorts, run the following commands:

sudo cmake --build build_darwin --target install

Installation of git main for Homebrew

From now on, you can use brew reinstall avrdude to catch up with git main.

Building using auto-tools.

./bootstrap
./configure CFLAGS=-I/opt/homebrew/include LDFLAGS=-L/opt/homebrew/lib (Homebrew Apple Silicon)
./configure CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib (Homebrew x86_64)
./configure CFLAGS=-I/opt/local/include LDFLAGS=-L/opt/local/lib (MacPorts)
make

For the next build, you may want to run make clean first.
