Hello folks, I’ve just wiped out and recompiled the whole GNURADIO on my
FC5 64, and unfortunately now no application runs anymore… even the
simplest dial_tone.py produces this output:
[matteo@localhost audio]$ ./dial_tone.py
Traceback (most recent call last):

Does anyone have any clue at this?
i have swig 1.3.31 and gcc 4.1.1
thanks in advance

I also just rebuilt, and got a different error.
This is on NetBSD 4.99.5, i386, swig 1.3.31, gcc 4.1.2.

This error is typically caused by having parts of the code compiled
with different versions of swig.
Try make clean, then rebuild and install.

I probably didn’t rebuild all since swig upgrade to 1.3.31.
I suppose the Makefile.am’s need to have a dependency on the swig
executable 
(I know, ENOPATCH…)
I got a different error, so I did make distclean and a full rebuild.
Now I get this, which I’ll look into when I get a chance.

This symbol is defined in a new file that was recently checked in,
gr_basic_block.cc, in gnuradio-core/src/lib/runtime. For some reason it
looks like this isn’t getting linked in during the compile on your
system, though it’s definitely in the Makefile.am list of source files.
