Compiling CHDK under Mac OS X

From CHDK Wiki

Building CHDK requires gcc 4.3.2 and the ARM GCC toolchain.

1. Install MacPorts - http://www.macports.org/install.php

2. Before you install gcc you'll need a working compiler, so Apple's dev. tool (from the installation CD) should be installed.

3. Install gcc v4.3.2. from the terminal, type - 

  sudo port install gcc43
  (type the admin password as prompted)
  (this took several hours on my macbook pro)

4. Install arm-elf-gcc v4.3.2 - from the terminal. 

  sudo port deactivate arm-elf-gcc
  sudo port install arm-elf-gcc

5. make gcc v4.3.2 the default compiler. 

  cd /usr/bin
  rm gcc
  ln -s /opt/local/bin/gcc-mp-4.3 gcc

6. make arm-elf-gcc v4.3.2 default. 

  cd /usr/local/arm/bin
  rm arm-elf-gcc
  ln -s /opt/local/bin/arm-elf-gcc-4.3.2

From here, the directions for compiling under linux will work Compiling_CHDK_under_Linux although the directions for installing the compiler and cross compiler can be skipped.
