That is the summary for the portaudio configuration part, not Pd's own
summary. Actually, Pd lacks a configuration summary, but you'll find
something like this much further up in the ./configure output  -
certainly above a line that says:

=== configuring in portaudio (/home/roman/pd-src/pure-data.git/portaudio)

Those lines probably are of interest:

checking for snd_pcm_info in -lasound... yes
checking for shm_open in -lrt... yes
checking for jack_set_xrun_callback in -ljack... yes
checking for jack_set_error_function in -ljack... yes


I _believe_ those have to be "yes" in order for ALSA and JACK to be
supported by Pd. The lines you posted just indicated that the portaudio
backend of Pd supports ALSA and JACK (and even OSS [who uses that
anymore]).


This is not the first time this has caused confusion. Would it be
possible to design ./configure in a way that it prints a Pd
configuration summary _after_ the portaudio configuration summary?
