Continuous Integration for Externals
by Thomas Mayer 29 Nov '16

29 Nov '16

Hello, after watching the talk and discussion from Katja about external development, I have started setting up my extension PuREST JSON for CI builds on travis-ci.org. Linux amd64 and cross compilation for Windows with MXE is working, I still have an error with compiling the 32 bit x86 version (see http://stackoverflow.com/q/40824438/124983). Obiously, I would like to set up a Mac build machine as well. What do I need to install on a clean system via command line? Has anybody else tried to do that before? After I have figured out the builds, I will write a summary on how to set it up correctly, and will try to build deken packages as well, and upload those to a test environment before actually releasing it. If anyone wants to work with the current state of affairs: The builds are setup with a file called .travis.yml, that contains the configuration variables and a list of build machines: https://github.com/residuum/PuRestJson/blob/travis-ci/.travis.yml I currently have two separate files for each environment, *_before_install.sh and *_script.sh, the former is used to set up the build environment and should in a way also function as documentation on how to set up your local machine, while *_script builds the files. https://github.com/residuum/PuRestJson/tree/travis-ci/travis-build I hope to be able to finish that this year and write some documentation about it as a Christmas / Chanukka gift to the community. Thanks, Thomas -- "When one's home has a really excellent computer capable of reaching other computers anywhere in the Galaxy, one scarcely needs to budge."

I just updated my pd.build (https://github.com/pierreguillot/pd.build/) repository that facilitate the creation of projects with CMake. I tried to add scripts that also facilitate the use of travis and I improved the documentation. I'll try to do a version of these scripts for Appveyor too and to do add more documentation on how to configure the CI. The approach is pretty simple and straight forward and has been made for simple and new projects, so I think that for most of you, the project won't fit exactly to your needs but perhaps you'll find some things useful in it. Cheers

I wouldn’t bother with both. If you want to explicitly build with gcc, you’ll need to install gcc via Homebrew and then set CC=gcc-6 to override the defaults. I was doing this the other day to check some errors that were only cropping up with a build on gcc and not clang. -------- Dan Wilcox @danomatika <https://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

[PD-announce] PURE DATA BENJOLIN
by Derek Holzer 29 Nov '16

29 Nov '16

PRESENTING the PURE DATA BENJOLIN The Benjolin is a standalone synthesizer designed by Rob Hordijk from the Netherlands in 2009 and available as an open hardware project online. It contains two oscillators (one LFO and one VCO), a voltage controlled filter and a circuit called a “Rungler”, which allows chaotic cross-modulation possibilities between the different parts of the circuit. Hordijk refers to the Benjolin as a circuit which has been “bent by design.” This Pure Data implementation of the Benjolin was coded by Derek Holzer in SEP-NOV 2016 in Helsinki, after several years of producing customized hardware Benjolins from his Berlin studio. The Pd Benjolin includes some modifications of the original design, including a Looping switch, an external Filter Source and an External Clock Source. FEEDBACK + BUG REPORTS WELCOME! DETAILS + DOWNLOAD: http://macumbista.net/?page_id=4690 Have fun at the the Pd-CON, folks!

Description for making deken packages
by Fred Jan Kraan 28 Nov '16

28 Nov '16

Hi, At http://puredata.info/docs/Deken is the beginning of a description on how to make packages for the deken-plugin (Help > Find externals in any modern Pd-vanilla version). The description might expand or even be moved to another page, but the URL above will be a starting point for deken info on puredata.info. Greetings, Fred Jan

Does anyone have copies of these two externals (creb and flatgui) for the Raspberry Pi? Or know where I can find the source code? For some reason, they're available for Windows, but not for the Raspberry Pi. Thanks. Thanks, I found most of them and was able to install them.
