Here are some instructions for building SimulAVR 1.0.0 from source on FreeBSD.
These instructions have been tested on FreeBSD/amd64 10.2-RELEASE.

Note that this installs simulavr under /usr/local/simulavr to keep it
from conflicting with other packages.

1) You'll need to first compile and install GNU binutils, bootstrapped
   for AVR cross-compilation.

	o Download binutils 2.25.1 and unpack the source
	o cd /path/to/binutils-2.25.1; mkdir avr
	o cd avr
	o ../configure --prefix=/usr/local/simulavr --enable-host-shared=yes --enable-shared=yes --target=avr
	o gmake
	o gmake install

2) Unpack the simulavr-1.0.0 source code

3) cd /path/to/simulavr-1.0.0

4) set the following environment variables:

	setenv PYTHON_LDFLAGS "-L/usr/local/lib -lpython2.7"
	setenv "LDFLAGS -L/usr/local/simulavr/x86_64-unknown-freebsd10.2/avr/lib -lbfd -L/usr/local/lib -lintl -rpath /usr/local/simulavr/x86_64-unknown-freebsd10.2/avr/lib"
	setenv CC /usr/bin/cc
	setenv CXX /usr/bin/c++

5) Run aclocal:

	aclocal

6) Run autoconf:

	autoconf

7) Run libtoolize:

	libtoolize --force

8) Run automake:

	automake -a

9) Edit configure as follows:

	o Change #! /bin/sh to #! /usr/local/bin/bash
	o Find "wish wish8.4 wish8.3 wish8.2" and add wish8.6
	o Change "set dummy tclsh" to "set dummy tclsh8.6"

10) configure simulavr as follows:

	./configure --prefix=/usr/local/simulavr --with-bfd=/usr/local/simulavr/x86_64-unknown-freebsd10.2/avr --with-libiberty=/home/wpaul/binutils-2.25.1/avr/libiberty -with-tclconfig=/usr/local/lib/tcl8.6 --enable-shared=yes --enable-python=yes

11) Apply the supplied diffs:

	patch < diff1
	patch < diff2
	patch < diff3
	patch < diff4
	patch < diff5
	patch < diff6
	patch < diff7
	patch < diff8
	patch < diff9
	patch < diff10
	patch < diff11

11) Build and install:

	gmake
	gmake install
