You are right – I have moved development across platforms given the same arm-elf-gcc/Eclipse/CDT IDE. Originally started off on SuSE Linux but moved to cygwin because of the many GUI artifacts with Eclipse back in the days. Now happily working on OSX.
OK – the libraries zip file is linke into the downloads page.
You should just unzip and put them in your /opt directory, and point your makefile accordingly.
I’ll be happy to hear whether you got a successful compile or not.
