Hi all, I am searching for a Pd implementation of a doppler effect as realistic as possible. Any recommendations? Any patch/external already made and well tested? Cheers FJ

PD 0.51-4 bug fix candidates
by Dan Wilcox 20 Dec '20

20 Dec '20

Howdy all, As quickly discussed on GitHub, there are a couple bugs which may warrant a 0.51-4 release. In addition, here is a little list of things I think would be good fixes to have: windows: save-to-/tmp/foo.wav bug networking & libpd: getaddrinfo() rejects dual stack socket settings on BSD and Android (https://github.com/pure-data/pure-data/pull/1232 <https://github.com/pure-data/pure-data/pull/1232>) mac: update patch window size after configure (https://github.com/pure-data/pure-data/pull/1236 <https://github.com/pure-data/pure-data/pull/1236>) multi-instance & libpd: set pd_this for readsf~ and writesf~ threads (https://github.com/pure-data/pure-data/pull/1227 <https://github.com/pure-data/pure-data/pull/1227>) writesf~: fix infinite loop on I/O error (https://github.com/pure-data/pure-data/pull/1224 <https://github.com/pure-data/pure-data/pull/1224>) mac: add back-ported patch for Tk 8.6.10 which fixes disabled Help menu items (https://github.com/pure-data/pure-data/pull/1226 <https://github.com/pure-data/pure-data/pull/1226>), note: requires re-building and packaging Wish.app in mac/stuff -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

OS's Audio Latency measures
by Esteban Viveros 16 Dec '20

16 Dec '20

I'm looking for a solution to have the values of input and output audio latency inside Pd. The same many DAW's show in audio preferences. The use case is I'm writing a patch using [abl_link~], that ensure music event synchronization whenever I set an offset parameter with the output audio latency. I found these: https://stackoverflow.com/questions/37729442/how-do-you-find-the-audio-late… which can be a start point.. or not.... once there is not jack. Thanks for any advance! -- Esteban Viveros www.estebanviveros.com

Miller only mentioned he was considering a quick bug fix release for the Windows issue, so I proposed to gather a small list of similar bug fixes. If he "signs off" on the list, then we can merge with develop or, as you say, he can accept them directly. I think option 1 is easier as we can do the integration and keep it clean, then he only has to merge develop into master. This would also be a big help for libpd as the networking fix is needed for Android and I can then release libpd 0.12 based off of the Pd 0.51-4 tag. > On Dec 10, 2020, at 12:00 PM, pd-dev-request(a)lists.iem.at wrote: > > Message: 1 > Date: Wed, 9 Dec 2020 21:14:40 +0100 > From: IOhannes m zmölnig <zmoelnig(a)iem.at <mailto:zmoelnig@iem.at>> > To: pd-dev(a)lists.iem.at <mailto:pd-dev@lists.iem.at> > Subject: Re: [PD-dev] PD 0.51-4 bug fix candidates > Message-ID: <448f6b95-da26-47da-bb68-cb23a54f28b2(a)iem.at <mailto:448f6b95-da26-47da-bb68-cb23a54f28b2@iem.at>> > Content-Type: text/plain; charset="utf-8"; Format="flowed" > > On 12/9/20 8:50 PM, Dan Wilcox wrote: >> Howdy all, >> >> As quickly discussed on GitHub, there are a couple bugs which may warrant a 0.51-4 release. >> >> In addition, here is a little list of things I think would be good fixes to have: >> >> windows: save-to-/tmp/foo.wav bug > > +1 > >> >> networking & libpd: getaddrinfo() rejects dual stack socket settings on BSD and Android (https://github.com/pure-data/pure-data/pull/1232 <https://github.com/pure-data/pure-data/pull/1232> <https://github.com/pure-data/pure-data/pull/1232 <https://github.com/pure-data/pure-data/pull/1232>>) > > +2 > >> >> mac: update patch window size after configure (https://github.com/pure-data/pure-data/pull/1236 <https://github.com/pure-data/pure-data/pull/1236><https://github.com/pure-data/pure-data/pull/1236 <https://github.com/pure-data/pure-data/pull/1236>>) > > +1 > >> >> multi-instance & libpd: set pd_this for readsf~ and writesf~ threads (https://github.com/pure-data/pure-data/pull/1227 <https://github.com/pure-data/pure-data/pull/1227> <https://github.com/pure-data/pure-data/pull/1227 <https://github.com/pure-data/pure-data/pull/1227>>) > > +2 > >> >> writesf~: fix infinite loop on I/O error (https://github.com/pure-data/pure-data/pull/1224 <https://github.com/pure-data/pure-data/pull/1224><https://github.com/pure-data/pure-data/pull/1224 <https://github.com/pure-data/pure-data/pull/1224>>) > > +10 > >> >> mac: add back-ported patch for Tk 8.6.10 which fixes disabled Help menu items (https://github.com/pure-data/pure-data/pull/1226 <https://github.com/pure-data/pure-data/pull/1226> <https://github.com/pure-data/pure-data/pull/1226 <https://github.com/pure-data/pure-data/pull/1226>>), note: requires re-building and packaging Wish.app in mac/stuff > > +1 > == > 17 > > > > should we prepare and merge this into 'develop', or does miller wants to > merge them separately? > > > gfmadsr > IOhannes -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Re: [PD-dev] Issues building PD 0.51.x
by Dan Wilcox 09 Dec '20

Before anyone looks further into the *details* ie. compiler flags, the configure overview output gives us a clue: > configure: > > pd 0.51.3 is now configured > > Platform: Unknown Clearly, configure failed and it never set the platform. The platform-specific / host checks failed and it probably half-defaults to building for Linux which is why it's trying to build the OSS audio backend. Now, looking at the beginning of the same configure log, we see: > checking build system type... x86_64-pc-msys > checking host system type... x86_64-pc-msys > configure: iPhone SDK only available for arm-apple-darwin hosts, skipping tests > configure: Android SDK only available for arm-linux hosts, skipping tests Hmm. The canonical host it's seeing is "x86_64-pc-msys" which is not one we actually support directly. What we support for building on windows with autootols is "mingw" see https://github.com/pure-data/pure-data/blob/master/configure.ac#L108 <https://github.com/pure-data/pure-data/blob/master/configure.ac#L108> So I think this a configuration issue with your setup as you are somehow not building with mingw as we have listed in the INSTALL.txt. One reason for this may be using the wrong shell, ie. MSYS2 instead of the explicit MinGW64 shell. It's been a few years since I've worked directly with MinGW & Pd, so the naming may have changed... which is also why we wrote the steps in INSTALL.txt. :) -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Issues building PD 0.51.x
by David Rush 09 Dec '20

09 Dec '20

Hi - I imagine that this is somehow my mistake, but I am having persistent problems with building PD 0.51.x from git under the latest MSys2/Mingw64 gcc $ gcc --version gcc (GCC) 10.2.0 Copyright (C) 2020 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. $ gcc -dumpmachine x86_64-pc-msys The issues seem to center around various WIN32 compatibility hacks. If I use the usual $ ./autogen.sh $ ./configure $ make clean $ make all the build fails while linking pd.exe /usr/lib/gcc/x86_64-pc-msys/10.2.0/../../../../x86_64-pc-msys/bin/ld: pd-s_audio_oss.o: in function `oss_open_audio': /c/Users/User/git/pure-data/src/s_audio_oss.c:305: undefined reference to `sys_setalarm' /c/Users/User/git/pure-data/src/s_audio_oss.c:305:(.text+0xee3): relocation truncated to fit: R_X86_64_PC32 against undefined symbol `sys_setalarm' /usr/lib/gcc/x86_64-pc-msys/10.2.0/../../../../x86_64-pc-msys/bin/ld: /c/Users/User/git/pure-data/src/s_audio_oss.c:394: undefined reference to `sys_setalarm' &cet interestingly, that build also generates a warning message while compiling s_inter.c (which defines sys_setalarm() under the right set of compiler flags) indicating that _WIN32 is not defined. s_inter.c: In function ‘sys_init_deken’: s_inter.c:998:4: warning: #warning unknown OS [-Wcpp] 998 | # warning unknown OS So if I instead build with CFLAGS=-D_WIN32, I get a different set of errors while building s_inter.c /usr/include/w32api/psdk_inc/_fd_types.h:100:2: warning: #warning "fd_set and associated macros have been defined in sys/types.

how to dinamically allocate t_atom & t_float size?
by Alexandre Torres Porres 05 Dec '20

05 Dec '20

Hi, when compiling ELSE for camomille in windows, me and Esteban are getting some errors. Offending pieces of code are when trying to do things like t_atom at[ac]; and t_float temp[n]; from stackflow <https://stackoverflow.com/questions/9881777/why-do-i-get-cannot-allocate-an…> we see "*You cannot allocate an array of unknown size with automatic storage duration in C++. If you want a variable sized array then you need to dynamically allocate it (or, better yet; just use a vector).*" Thing is we don't know how to proceed here and are looking for hints, maybe showing how other objects in Pd deal with this. BTW, there's an issue <https://github.com/porres/pd-else/issues/881> on ELSE's repository. Thanks Alex
