I tried building this program on Windows and failed. Since it's
missing in viterbi/CmakeLists.txt, I fail to see it's built by
default. How did you compile it? Are you sure it wasn't written
on a big-endian machine?
under GNU/Linux
g++ -c encode.cc
gcc -c viterbi.c
gcc -c tab.c
gcc -c metrics.c

If I modify viterbi.c in gr-fec/viterbi (swapping the polynomial coefficients)
#define POLYB 0x6d
#define POLYA 0x4f
then
$ xxd word.bin

and
$ cat word.bin | ./encode > t
then t is
