Hi,
I am learning TOSSIM thanks to the TOSSIM tutorial and I have a segfault
when running test.py (or python_test.py) in the apps/RadioCountToLeds
directory.
I work on Xubuntu Hardy Heron ($ uname -r => 2.6.24-23-generic)
I use TinyOS 2.1
$ gcc -v => version gcc 4.2.4 (Ubuntu 4.2.4-1ubuntu3)
$ python -V => Python 2.5.2
To successfully built the micaz TOSSIM library I had to add :
$ export CFLAGS="-I/usr/lib/gcc/i486-linux-gnu/4.2/include -I/usr/include"
before
$make micaz sim
But I have warnings with the g++ command, e.g. (maybe its a clue):
/opt/tinyos-2.1.0/tos/lib/tossim/tossim_wrap.cxx: In function «PyObject*
_wrap_nesc_app_t_numVariables_set(PyObject*, PyObject*)»:
/opt/tinyos-2.1.0/tos/lib/tossim/tossim_wrap.cxx:1999: attention :
deprecated conversion from string constant to «char*»
/opt/tinyos-2.1.0/tos/lib/tossim/tossim_wrap.cxx:2000: attention :
deprecated conversion from string constant to «char*»
So this is the trace with : $ gdb /usr/bin/python and (gdb) run test.py (the
last lines refer to sim_noise.c)
