Perhaps? The hashtable code is compiled into c-support.o, which isn't being linked in. This is because sim-cygwin is an old Makefile. The new Makefile links it in.
how do i get the new Makefile and how do i link it? Do i need to download and reinstall tinyos or something? Also i tried using 'make micaz sim' , but this throws numerous 'undefined_reference' errors like say /opt/tinyos-2.x/tos/lib/tossim/tossim_wrap.cxx:3065: undefined reference to `_Py Long_FromUnsignedLong' build/micaz/pytossim.o(.text+0xdc71):/opt/tinyos-2.x /tos/lib/tossim/tossim_wrap. cxx:3065: undefined reference to `_PyInt_FromLong' build/micaz/pytossim.o(.text+0xdcca): In function `_Z22SWIG_From_long_SS_longx': /opt/tinyos-2.x/tos/lib/tossim/tossim_wrap.cxx:3073: undefined reference to `_Py Long_FromLongLong' build/micaz/pytossim.o(.text+0xdcda):/opt/tinyos-2.x /tos/lib/tossim/tossim_wrap. cxx:3073: undefined reference to `_PyInt_FromLong' build/micaz/pytossim.o(.text+0xdd43): In function `_Z23SWIG_FromCharPtrAndSizePK cj': /opt/tinyos-2.x/tos/lib/tossim/tossim_wrap.cxx:2955: undefined reference to `_Py String_FromStringAndSize' build/micaz/pytossim.o(.data+0x1a0): In function `SWIG_TypeCompare': /opt/tinyos-2.x/tos/lib/tossim/tossim_wrap.cxx:398: undefined reference to `_PyO bject_GenericGetAttr' collect2: ld returned 1 exit status make: *** [sim-exe] Error 1 I checked the tinyos-help thread on this. It says i need to change the sim.extra file to reflect the correct python version (in my case it is 2.3.4). I made this change to the sim.extra file. The help also says i need to have /usr/lib/pythonX.Y , but i do not have anything in my /usr/lib directory , but have a directory by name 'python2.3' at location /lib/python2.3 I copied this directory to /usr/lib , but this does not work. Now how do i get over this? Which rpm for python-devel do i need to download? Where can i find it? will it work for cygwin? I know these are too many questions but please do let me know Preeti Phil
