linking into shared object ./_TOSSIM.dll
g++ -fpic -W1,--enabled-auto-image-base build/micaz/pytossim.o build/micaz/sim.o build/micaz/tossim.o -L/python2.4 -lstdc++ - lpython2.4 -o _TOSSIM.dll
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../libcygwin.a(libcmain.o):: undefined reference to [EMAIL PROTECTED]'
I googled the error for some solutions, and tried adding "-Wl,u,[EMAIL PROTECTED]" to the linking command but that didn't help. Any ideas on this one?

Hi,
I'm having the same problem with my python libraries. I tried the "configure;make" with Python 2.5 and changed my sim-cygwin.extra and sim.extra but had no luck. Now it's complaining about "Python.h : No such file or directory". Can you give me some insight into how exactly do I make it find Python.h? What else must I point sim-cygwin.extra to?On 10/8/06, Sivan Toledo <[EMAIL PROTECTED]> wrote:It seems that there is no shared-object library in the python package of
cygwin (neither in the version on that is part of the cygwin bundle on
tinyos.net nor in the current versions on cygwin.com), and that there is
nothing called cygwin-devel, so I guess that this library might have
been created by a full "configure;make;" of the python sources.
If you have a working copy of the .so file, I would appreciate a copy to
try to void the "configure;make" hassle.
