I found something that solved it, I had build a switch into the bang-method to chose function, replacing this with if, if else... statements solved the problem for some reason.

hello
I am basically working on my first pd externals, 1 of them is using functions of int which I have in a separate .h file. These are functions of a seed and and a prime-number, and generate a series of integers by iteration / repeated bang. . The external compiles and looks like it is working, but it is not generating the right number series, which I can verify both with a python-script and also with a little c program using exactly the same .h file for the functions. I am extremely puzzled and have been trying all kind of stuff to find out what is going on. There are of course 2 crucial variables in the struct holding the external : the seed and the prime. I have included some set-methods which post when a variable has been set to a value, so it looks like that is working ok. I have been using ints in the fuctions, ints in the struct and ints in the bang-method and can not really see where something could have been "lost in translation" Any clues where to look further?? Is someone interested in looking at it if i send the code?
Thanks in advance. Vilbjørg

hello
trying to get PD to work on a RaspberryPI with the Wolfson audiocard.
At the moment I am following this procedure:
http://journeytounknownsoundscapes.blogspot.nl/2014/05/using-raspi-wolfson-audio-card-and-pure.html

but keep getting a message
W: GPG error: http://apt.puredata.info wheezy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9F0FE587374BBE81

would someone know where to find further info on this

also tried "apt-get install puredata", which installs fine and opens and runs sound if one chooses NOT to use the WolfsonCard , with the card chosen I get "I/O stuck"

any suggestions to get pd working here are very welcome
thanks in advance

Got it working for some (for me unknown ) reason the pd audio problem was solved by changing raspi-config :: not logging directly onto a desktop but start from text console, then 'startx' to get a desktop and then I l started pd interface or nogui from the terminal

so the process is simple:
1. OS img (including the wolfson drivers) https://docs.google.com/file/d/0BzIaxMH3N5O1RUdSa19od1ltTjg/edit?pli=1 (this is made by Ragnar Jensen, the 'official' image must be corrupted, I spent several days trying to download it and decompress it without success)
2014-01-07-wheezy-raspbianW.img onto sdcard (I unzipped .zip on debian, macos wouldn't do it for me with this file)
2. start raspberry pi with sdcard and (important for pd) by configuration just choose to boot to the text console.
3. reboot, "startx" to launch desktop
4. open terminal
5. "apt-get update"
"apt-get install puredata"
5. pd (the wolfson card is even default in pd preferences)
