They are good instructions to follow.  To debug the segfault you need to
use gdb.  If you are in the dcpomatic source directory, to

run/dcpomatic --debug

and then when it crashes do

thread apply all bt

and the output should give us some clues.

The stable branches are:

dcpomatic: v2.12.x
libdcp: v1.5.x
libsub: v1.3.x

I don't use an IDE (just Emacs and the terminal), but you can use whatever
you like.

Kind regards,
Carl
