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.

For troubleshooting, some of the tips here written for Tiger are applicable.
