why do you not use the Debian packages? (oh, because xenial still has Pd-0.46-7)

the mailinglist archives should give you instructions on how to properly build an uptodate Pd debian package.

but I can't seem to get the audio working. I have Ubuntu in my Macbook Pro (mid 2010) and I have followed the instructions in "install.txt". checked the dependencies and after I finish it says:

Configuration summary:

Target ...................... x86_64-unknown-linux-gnu C++ bindings ................ no Debug output ................ no

ALSA ........................ yes ASIHPI ...................... no

OSS ......................... yes JACK ........................ yes

good.

when I run pd in command line it says:

priority 94 scheduling failed.

how do you "run pd"? anyhow, this is only to indicate that Pd uses non-realtime priviliges; which should work as well.

but in pd I have no device to select in audio settings and if i try to select anything, the pd window spits out this:

/dev/dsp (read/write): No such file or directory (now will try write-only...) /dev/dsp (writeonly): No such file or directory /dev/dsp (readonly): No such file or directory

because the default is (still) to use the OSS backend, which is obviously not enabled on your system.

any ideas what I am doing wrong?

start "pd -alsa" or "pd -jack" (or set the audio backend via the media-menu) afair, the Debian packages have set the default to "-alsa", so it usually just works.

Hello list,

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?
