It is what I did: "tinyos external c code" http://www.google.com/search?client=safari&rls=en&q=tinyos+external+c+code&ie=UTF-8&oe=UTF-8 Two links that look promising are: http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2011-October/052635.html http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2007-September/028079.html You can also do reasonable searches on http://www.mail-archive.com/tinyos-help@millennium.berkeley.edu/ So please try to do more research for generating noise on the list. We don't mind helping, but would like it much better if you exhausted more of what you could determine on your own first. eric > > Regards, > > Mash'al. > Jordan > ------------------------------ > *From:* Eric Decker <cire...@gmail.com> > *To:* Mashal al-shboul <shboul8...@yahoo.com> > *Cc:* "tinyos-help@millennium.berkeley.edu" < > tinyos-help@millennium.berkeley.edu> > *Sent:* Friday, February 24, 2012 10:41 PM > *Subject:* Re: [Tinyos-help] urgent need for help about error:" undefined > reference to" > > > you've caused code to be included that references an external. > > The linker is complaining about not being able to find ezcompress. > > you will need to research where to get the ezcompress code and will then > need to figure out yourself how to include that. > > this is basic C programming with separate modules.
