Hello Barry,
Apparantly, the module has portability issues (will build on x86 but won't build on ARM) due to data type issues. To build the package, you will have to edit lib/baudot_encode_bb_impl.h:
"static const char ascii_to_letters[128]" should become
"static const signed char ascii_to_letters[128]", and
"static const char ascii_to_figures[128]" should become
"static const signed char ascii_to_figures[128]".
That will allow the module to build, although you may have to make further changes to get "Boudot Encode" block working correctly (I didn't test that; maybe I should make a pull request after that).
Regards,
Kyeong Su Shin

제목: Re: [Discuss-gnuradio] RTTY receiver
Thank you for your response. Since this is my first issue on
'discuss-gnuradio', I am not sure how to get my reply to you posted in
the thread. This looks like it might work. If not, please let me know
what to do.
I did the "sudo ldconfig" and it got rid of the "include could not find
load file: GrPython", but not the other problem, so I decided to start
from scratch.
I have
Raspberry Pi 3 B+
Rasbian Linux (v2)
I deleted the folder 'gr-radioteletype'
download zip from https://github.com/bitglue/gr-radioteletype
extract zip to /home/pi
cd ~/gr-radioteletype-master
mkdir build
cd build
cmake ../
make

Both of the error messages were repeated *many* times. I looked at the
code for baudot_encode_bb_impl.h, but could not see any problems with
it.
I appreciate any help you can give.
Best wishes,
Barry
