It builds find on my ARM 64 Odroid running jessie. Maybe it just doesn't build on the raspberry pi 3. I'm running a slightly dated version of gnuradio - 3.7.12git-295-ga0adcd33. -- Cinaed 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 > > > ------------------------------------------------------------------------ > *보낸 사람:* [email protected] <[email protected]> > *보낸 날짜:* 2019년 6월 11일 화요일 오전 2:56:02 > *받는 사람:* Kyeong Su Shin > *참조:* [email protected] > *제목:* Re: [Discuss-gnuradio] RTTY receiver > > Thank you for your response.
