you know, "edkellytista9/LPCToolkitPd" can be about everything; why
would i have thought about a github project?

anyhow.

compiling your file prints a huge fat warning:
> mbc_lpc~.c:661:1: warning: control reaches end of non-void function
[-Wreturn-type]

which is indeed true, and it is telling you that your constructor
function lpc_new() is not returning anything (and definitely not an object).

the externals howto [1] says:
> The constructor has to return a pointer to the instantiated
> data space.

but even with that fixed, it doesn't load.
now i've asked you to:
- run Pd with "-verbose".
- check the console.

to which you replied:
> tried...(all pd search paths)...and failed
> tried...(current directory)...and failed

however, when i try to load your external i get:
> tried /tmp/zmoelnig/LPCToolkitPd/mbc_lpc~.l_ia64 and succeeded
> load_object: Symbol "mbc_lpc_tilde_setup" not found

which is writing out as plain as possible that your external misses the
only function that it *must* have in order to be any use to Pd: the
callback function that allows your external to bootstrap.
(while blindly copying, you renamed your object but forgot to rename the
setup function).


apart from that:
- please mark all your functions as static. you will get nameclashes
otherwise. making your objects use totally different functions than you
expect (and possible making the object of other people use different
functions).
- template Makefile 1.0.14? seriously? consider switching to
pdlibbuilder. it's much nicer. for starters, it doesn't make bogus
file-extensions on linux/amd64.

ok, so, as of now, cyclone officially needs to be loaded only as a library,
but all this does is that it automatically adds cyclone's path to Pd's
search paths, so you can load the majority of objects without the
"cyclone/" prefix. Please note the commonly neglected fact that cyclone
needs to load as a library in order to load the non alphanumeric objects.

Having said all that, I can say cyclone won't likely ever decide to compile
as a single file, I think we reached the perfect spot here.

[PD] why doesn't "libdir" work in Pd Vanilla?

[Alexandre Torres Porres]

I'm trying to test libdir in Pd Vanilla, I used Pd 32 bits (0.48-1-i3866)
on macOS, and got the [libdir] from deken that seems to work only on it.
This is the one that comes with Pd Extended.

I added "libdir" to startup, but I get a "libdir: can't load library" error.

So, any ideas why it wouldn't work?

yeah, to avoid the error, the path just needs to start with a "+"
character. I learned that after I opened an issue about it here
https://github.com/pure-data/pure-data/issues/351 - which I guess I can
close as there's nothing too weird about all this, but i'd like an answer
why the "+" is needed.

So, anyway, if the thing about Gem comes from this new code, I already
figured it out and am including it in Cyclone, so we're good. I'm just
curious if this was supposed to be working on old Pd extended and with the
Gem available in deken.

Re: [PD] parametric equalizer

[Raphaël Ilias]

Thanks Alex and Dan,
I am very busy now but I'll look into your solutions ASAP.

I am aware of ggee objects for biquad~ coefficient calculations.
Tough I understand the idea to "split the spectra" of a signal with
low-pass, band-pass and high-pass filters...  what is still unclear to me
is : since the outputs of the filters are then mixed together, how to make
sure that overlap correctly so that if the 3 (low, band and high) filters
have 0db gain ([*~1]) the sum of the 3 together will be similar to the
input (flat response), like it does when your mixer's EQ knobs are all
centered...
and what does it really mean when you turn it counter-clockwise, for
example "MID knob" to -6 dB ?
I suppose it isn't a rejection/notch filter ? So it's just a bandpass
filter with amplitude 0.5 / -6 dB and then mixed with the outputs of the
lowpass and highpass filters ?
Probably there is no perfect design, but I wonder what details I should be
aware of.

But I will study the abstractions/objects you mentioned.

Re: [PD] polynomial pairs in lpc filter

Apologies - I'm trying to do this while buying a house...I don't know if that 
is simple in Austria but it isn't here.

But, I was indeed firing blind myself. I assume you are referring to line 665 
to 668 in mbc_lpc~.c:
  mbc_lpc_class = class_new(gensym("mbc_lpc~"), 
  (t_newmethod)lpc_new, 
  0, sizeof(t_lpc),
  CLASS_DEFAULT, A_DEFFLOAT, 0);

After reading your email I assumed it was something new, but of course I had 
just copied, pasted and altered code from a previous external (and forgot)
Perhaps it's to do with linking to libm, so I'll check the makefile once I'm 
back in a reasonably stable (time-wise) environment.

BUT - I've never really understood (in ~13 years of external development) what 
all those args to class_new() did before, and you've forced me to look deeper 
into m_pd.h
I should thank you for that - and yes, I learned how to write externals by 
reading your howto, in 2005 I believe.

Thanks,
Ed

hmm... each and every one?

just to make sure: with "external" you mean some dynamically loadable
file that somehow adds new [object]s to Pd?

if we can agree on that, you might want to read my externals howto [1].
(for completeness sake, there are other ways to write externals; but so
far the only thing i've understood so far is that "it doesn't work",
making it impossible to tell which path you took before you lost your way).

Re: [PD] CONTEXT V3.0.2 tests. (was: How to declare custom libraries in abstractions)

[Liam Goodacre]

What do you usually do to use objects from these libraries? All externals 
objects are declared as [library/object] inside Context, so it it works outside 
the patch, I don't understand why it wouldn't work inside. Can you for instance 
create [iemguts/canvasargs] in a regular patch?

Good to know that my testing was useful.

However, I don't know if this is important for your testings, but I DO have 
iemguts and zexy (and cyclone, flatgui, hcs and list-abs... for the ones you 
use) already installed via Deken (so on Mac OS X now they're put in

I'll look deeper into Context when I have time, but it looks a huge amount of

Thanks Raphaël. It's especially good to know that Context works on Mac, since I 
haven't tested it there myself.

It looks like you don't have the zexy, iemguts or else installed. You can get 
them from Help-->Find Externals if you want, but the important thing is that 
Context works with the built in externals.

If you want to understand about resizing and shifting toggle floats, you can 
look at helpfiles/GUI_manioulation.pd

Hi,

I might be late for the answer... I didn't know Context, but I just had a quick 
look about it and seems interesting concept.
I am trying "externs-test.pd". I am using Macbook Pro 2012 with OS X 10.10.5 
Yosemite and pd-vanilla 0.48-1

1. I don't have any "couldn't create" on load

2. I don't really know yet how to "resizing and shifting toggle floats"

3. The 4 objects seems to create but none of their help-files open with 
"right-click > Help"

4. I quit pd, renamed the 8 libraries folder as "_OUT_libraryname/" and 
re-opened "externs-test.pd" :

1B. Now I have a lot of "couldn't create" on load :
- demux
- l2s
- sort
- mux
- urn
- else/break &
- msgfile
- iemguts/initbang
- else/fromany
- else/toany
- else/routeall
- s2l
- time
- iemmatrix/matrix
- iemmatrix/mtx_check
...
and a few chords that couldn't be created, and missing arrays (0-IDshare)

2B : still don't know how to "resize and shift toggle floats"

3B : [s2l] and [else/toany] don't create. The other two do open their 
help-patches with "right-click > Help"

NB : i don't have else library installed originally


Hope this helps !

Hi Liam,

Amazing patching!

-


1: When you open this patch, are there any "couldn't create" messages in the 
console? If so, tell me!


There are not "couldn't create" on "externs-test.pd" but I found:

 cyclone/tanh~
... couldn't create

going through examples that use [docfiles/glock~].

On "12_overlay_examples.pd" & 
"13_embedding_(takes_several_minutes_to_load!).pd" i get:

... couldn't create

2: Does Context seem to be working correctly? Try resizing it and shifting 
toggle floats to see.;


Resizing seems to work. I don't know what you mean with "shifting toggle floats 
to see".

Notes: when using "externs-test.pd" if I click on the *lower left toggle* i get:

0-crxyoff: no such object
0-roff: no such object
0-notsafe: no such object
0-roff2: no such object
0-crxyoff: no such object

But is not the case if I create a new patch and a new [context].

3: If the following objects have created correctly, can you call the helpfiles?


I can not open the help files.

Note: I have temporarily switched off my normal externals folder.

I can not open "00_first_time_tutorial.pd" it crashes Pd.

I've uploaded a draft of Context with externals which I hope will work "out of

simply delete the relevant folders from the main Context folder, and then the

i figure this just a PATH issue (PATH missing "/usr/local/bin")

for interactive shells (which is what you get by opening Terminal.app),
this seems to be automatically handled by ~/.bashrc.
at least mine (on an OSX machine) looks like:

~~~
# only run in interactive mode:
[ -z "$PS1" ] && return

export CVS_RSH=ssh
export PATH=${PATH}:/usr/local/bin
if [  "x${EDITOR}" = "x" ]
then
 export EDITOR=/usr/bin/vi
fi
~~~

which makes it clear that non-interactive shells (and non-bash) shells
do not get the merits of /usr/local/bin/...

you could:
- call programs by absolute paths (which is what you already do; it's
somewhat ugly as it breaks everything if the paths ever change)
- add something like "PATH=/usr/local/bin:${PATH}" at the beginning of
your script (after the hashbang) and don't worry any more.
- add /usr/local/bin to your global search paths. e.g. [1].

hmm... each and every one?

just to make sure: with "external" you mean some dynamically loadable
file that somehow adds new [object]s to Pd?

if we can agree on that, you might want to read my externals howto [1].
(for completeness sake, there are other ways to write externals; but so
far the only thing i've understood so far is that "it doesn't work",
making it impossible to tell which path you took before you lost your way).

I am taking a stab at doind things I've never done before, and I'm quite out of 
my depth! :~}

Ok. I've never used class_new() and pd_new() before. Can you point me in the 
direction of an external that uses it?

does Pd find your external?
if so, does it print an error message? (raise verbosity in the
Pd-console to "DEBUG" as well).

for fabs() you must link against libm.

also, if the *only* external function you are using from m_pd.h is
[i]fft_mayer(), then it is pretty clear that the external cannot load:
you need at least class_new() and pd_new() as well...

yes.
but i wasn't talking about this.

- remove all (Gem-related) paths and libs from your startup settings (or
start Pd with "-noprefs".
- instantiate one of Gem's abstractions, e.g. [hsv2rgb] -- it should fail
- load the Gem library (e.g. "-lib Gem" or [declare -lib Gem])
- instantiate one of Gem's abstractions, e.g. [hsv2rgb] -- it should
instantiate.
