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

My [hid] 0.7.1 fork builds without XCode
by Albert Rafetseder 24 Nov '20

24 Nov '20

Hello, TL;DR: Here's my fork of [hid] version 0.7.1 that needs no XCode to build on Mac OS X (10.11.6 on my end, hopefully on later macOSses too): https://gitlab.com/aaaaalbert/pd-hid It's based on https://git.puredata.info/cgit/svn2git/libraries/hid.git/ Long version: I'm just re-learning Pd and decided it would be a good idea to build it on my ageing Mac (which went marvelously!), and also build [hid] which didn't go that smoothly for me. In the versions of [hid] that I inspected [1], it requires XCode to build on Darwin, as the Makefile [2] passes to xcodebuild an XCode project file [3], lets XCode do its thing, then continues. I couldn't get my version of XCode to use the project file, running into this error: ``` xcodebuild: error: Unable to read project 'HID Utilities Slib.pbproj'. Reason: Project file 'HID Utilities Slib' was written by an unsupported Xcode version (38) ``` I soon gave up on hacking the project file and instead wrote a sub-Makefile for the Mac parts [4], adapted the main Makefile [5], and voilà! I can use a spare JoyCon game controller to feed button presses to my patches. I've built and manually tested my version of [hid], tentatively labeled 0.7.3, both on Mac (OS X 10.11.6) and Linux (Xubuntu 19.10) with PureData 0.50-2 as tagged on GitHub [6]. Outlook: I'm thinking of adding accelerometer support for the game controller, and perhaps sort out the values that hatswitches produce on different OSses. Thanks, Albert. [1] Here are the different versions / forks of [hid] that I found: * 0.7.1 --> https://git.puredata.info/cgit/svn2git/libraries/hid.git (That's the one I based my work on.) * 0.7 --> https://sourceforge.net/projects/pure-data/files/libraries/hid/hid-0.7.tar.… (as linked from the Pd wiki) * 0.7 --> https://salsa.debian.org/multimedia-team/pd/pd-hid/ * 0.7.1 --> https://github.com/agraef/purr-data/blob/master/externals/hid/ Binary releases from deken: * 0.7.1 --> http://puredata.info/Members/zmoelnig/software/hid/ * 0.7.1 --> http://puredata.info/Members/chr15m/software/v0-0extended/hid/ [2] original Makefile: https://git.puredata.info/cgit/svn2git/libraries/hid.git/tree/Makefile#n200 [3] XCode project file: https://git.puredata.info/cgit/svn2git/libraries/hid.git/tree/HID%20Utiliti… [4] sub-Makefile for Mac build, not using XCode: https://gitlab.com/aaaaalbert/pd-hid/-/blob/osx-build-without-xcode/HID%20U… [5] adapted main Makefile: https://gitlab.com/aaaaalbert/pd-hid/-/blob/osx-build-without-xcode/Makefile [6] https://github.com/pure-data/pure-data/releases/tag/0.50-2

pdmax with settable sampling rate
by João Pais 27 Sep '20

27 Sep '20

Hello list, the current version of pdmax only allows the pd sample rate to be set as a parameter "-sr xxx". Would it be possible to send that as a pd~ message, so that it can be changed after the object has been initiated? This would allow for the same patch to be used with different sampling rates. In my particular case, it would be ok to stop the pd sub-process to change pd's sample rate, and then reinitiate it. Best, Joao

Static/dynamic linking glibc
by Esteban Viveros 06 Sep '20

06 Sep '20

Hello list! I´m working in compiling Cyclone and Else binaries. We have an issue <https://github.com/porres/pd-else/issues/779> with glibc version at run binaries in ubuntu 18.04 (glibc 2.27). I´m compiling it in Ubuntu 20.04 (glibc 2.29). Since compiling it libs with pd-lib-builder I obtain dynamic link against glicb I think about static link glibc 2.29 using -static flag. 1. I´m looking about how to set this flag to pd-lib-builder avoiding to break other default assignaled flags. 2. If I have success in embbed glibc in external binaries this cause problems with the use of licenses that are more permissive than GPL when using these libs to make other softwares? Maybe the best is downgrade glibc to 2.27 and offer support from linux system with this version? what is the standard procedure in distributing external binaries for these cases? Thanks Esteban Viveros -- Esteban Viveros www.estebanviveros.com
