Phil, I double checked that I only installed the cygwin packages, not
the Linux one. Here is a list of the RPM's that I installed:

Trying the command "OSTYPE=cygwin make micaz sim" did make things a
little better. (It seems that OSTYPE is not set at all on my machine for
some reason; when I printenv OSTYPE I get nothing back. It is a pure
TinyOS cygwin that I installed from the tar.gz on the TinyOS web site,
not from cygwin.com.)

So it's failing to find the python library. I think that it is indeed
not installed and that it was not included in the cygwin installation on
the TinyOS web site. Here is the output of the commands that search for
this library (it's not on my system) and that enumerate the
python-related cygwin packages; it only includes the python base
package. So perhaps something like python-devel or something similar is
missing from the installation. I'll try to find a compatible python
developement package.
Thanks a lot. Sivan

I don't think the problem is with the version of python. The command
that fails is
g++ -shared -fPIC build/micaz/pytossim.o build/micaz/sim.o
build/micaz/tossim.o -lstdc++ -o _TOSSIMmodule.so
The unresolved references are in pytossim.o, and they seem to refer
to some Python-related library (symbols like _PyString_FromString and
__imp__PyExc_NameError). I don't see on this command line the library
from which they should come. They are not in tossim.o (I checked with
nm).
The instructions in the TOSSIM tutorial seem pretty similar to the
one in the first tutorial, it basically just say to run "make micaz
sim" in apps/Blink.
Hm. This is weird. -fPIC suggests that it thinks it's compiling for
Linux, not Cygwin. The default sim.extra tries to figure out which OS
you are with the OSTYPE environment variable. If it is "cygwin", it
compiles for Cygwin, if "darwin" it compiles for Mac OSX, otherwise
Linux.
What is this environment variable on your machine? Can you try
OSTYPE=cygwin make micaz sim
and see what happens?
The other possibility is that you don't have the Python development
libraries. I had though that this was standard on most Cygwins, but...
did you install the one linked on the TinyOS site?
Phil
