Installing TinyOS-2.x on Mac OS X (Snow Leopard)

• Install NesC, the AVR GCC compiler and the MSP GCC compiler by following the instructions at the "Unofficial MacPorts for TinyOS" page.

• Install gcc44 from MacPorts and softlink /opt/local/bin/gcc-mp-4.4 to gcc, and /opt/local/bin/g++-mp-4.4 to g++, in the directory /usr/bin.

 Note: gcc43 works too.

 Note: the apple-gcc* compiler does not work because it will complain that "-c" is not a valid option to the preprocessor.

• Put "CFLAGS+=-D_FORTIFY_SOURCE=0" in your Makefile.

• For simulations that involve opening a lot of files, e.g. simulations involving Flash memories, in the shell, type "ulimit -n <number>" where <number> is a high-enough value.

Troubleshooting

• If Java complains about not finding the JNI libraries (getenv, toscomm), try running it using sudo.

• If you encounter the error can't open config file "/etc/avrdude/avrdude.conf", either softlink /opt/local/etc/avrdude.conf to /etc/avrdude/avrdude/conf, or put the following code in the file $TOSROOT/support/make/avr/avr.rules after the line AVRDUDE_CONF ?= /etc/avrdude/avrdude.conf:

 ifeq ($(findstring Darwin, $(shell uname)), Darwin)
   AVRDUDE_CONF := /opt/local/etc/avrdude.conf
 endif
