[edit] Troubleshooting

[edit] Unknown opcode `typedef' errors

First, try switching gcc version from the Terminal:

  $ avr-gcc-select 4

If the problem still persists, recompile your AVR toolchain (see below).

[edit] Avr-size: invalid option -- C

From the included Makefile, change this line:

  @avr-size -C --mcu=${MCU} ${TARGET}

To this:

  @avr-size -A ${TARGET}

[edit] Compiling AVR Toolchain

[edit] Install Xcode

Make sure that you have Apple's Xcode Developer Tools installed first. This is necessary to build the toolchain.

[edit] Install binutils

Download the newest version of binutils.

Extract the file and cd to its folder in the Terminal.

From the Terminal:

  ./configure --target=avr
  make
  sudo make install

[edit] Install gmp

Download the newest version of gmp (needed to compile gcc).

Extract the file and cd to its folder in the Terminal.

From the Terminal:

  ./configure
  make
  sudo make install

[edit] Install mpfr

Download the newest version of gmp (needed to compile mpfr).

Extract the file and cd to its folder in the Terminal.

From the Terminal:

  ./configure
  make
  sudo make install

[edit] Install gcc

Download the newest version of gcc.

Extract the file and cd to its folder in the Terminal.

From the Terminal:

  mkdir obj
  cd obj/
  ./configure --target=avr --enable-languages=c,c++ --disable-libssp --disable-nls
  make
  sudo make install

[edit] Install avr-libc

Download the newest version of avr-libc.

Extract the file and cd to its folder in the Terminal.

From the Terminal:

  ./configure CC=avr-gcc --host=avr
  make
  sudo make install

[edit] Install libusb-0.1

If you are planning to use an AVRISP mkII USB programmer you must install libusb before compiling avrdude. Otherwise, skip to installing avrdude.

Important: Install the legacy version of libusb

Extract the file and cd to its folder in the Terminal.

From the Terminal:

  ./configure
  make
  sudo make install

[edit] Install avrdude

Download the newest version of avrdude.

Extract the file and cd to its folder in the Terminal.
