But it has problems and no one currently maintains it. As you've found out the dependencies are broken. Also I personally don't support it. Haven't found a volunteer to update the wiki pages. The preferred way of installing tinyos source is via github. ie. git clone https://github.com/tinyos/tinyos-release.git for the current released version and git clone https://github.com/tinyos/tinyos-main.git for the development tip. > > > > ------------------------------ > *Von:* Eric Decker <[email protected]> > *An:* "[email protected]" < > [email protected]> > *CC:* Martin Kjeldsen <[email protected]>; " > [email protected]" <[email protected]> > > *Gesendet:* 12:19 Freitag, 5.Juli 2013 > *Betreff:* Re: [Tinyos-help] Strange memory bugs > > > 4.6.1 has known bugs. > > following the instructions at http://tinyprod.net/repos/debian/ > > > On Fri, Jul 5, 2013 at 1:24 AM, [email protected] < > [email protected]> wrote: > > The application in which the bug occurs is about 10k LOC, so posting it > wouldn't help here.
