Ok, I finally got the addon to compile and run correctly (tests
passed !)<br class="">
The answer was simple : just use the master branch of libpd.<br class="">
I started tweaking the Makefile of v0.11.0 to include g_undo.c
(which I noticed was containing the canvas_undo_undo function) in
the sources but it was not sufficient.<br class="">
So I grabbed the master branch after seeing it seemed more
up-to-date, and voilà.<br class="">
I still need to test this local version with the node project that
loads externals, but at least I have my own working local version
which I can modify at will.<br class="">
<br class="">
Thanks again for the help, I'll let you know how this goes with
externals.<br class="">

For the moment I'm using the default Makefile of libpd (version
tagged 0.11.0), which makes use of the -DHAVE_LIBDL flag.<br class="">
It can't find the HAVE_LIBPD definition anywhere, though ... is
this normal ?<br class="">
Sorry for my lack of knowledge of autotools, makefile, etc, but
should I add `HAVE_LIBPD =` at the beginning of the Makefile ?
(e.g. after `LIBPD_IMPLIB =` and `LIBPD_DEF =` lines ?)<br class="">
Or should it be added to the cflags with -DHAVE_LIBPD ?<br class="">
<br class="">
I added both and the addon builds fine (I got rid of the char *
related errors by adding the -fpermissive flag), but I still get
stuck when trying to run the js automated tests :<br class="">
they fail with an `undefined symbol` error, the undefined symbol
being `canvas_undo_undo`.<br class="">
Sounds familiar to anybody ?<br class="">
I have no idea how to solve this ...<br class="">

Thanks,<br class="">

<div dir="ltr" class="">If you're building libpd via a custom Makefile,
see the flags used in the libpd Makefile. Also, if you're
using the libpd Makefile, double-check that HAVE_LIBPD is
being defined.</div>

Yesterday I tried to recompile the node addon to use it
locally but got into other trouble.<br class="">
I first recompiled libpd with MULTI=false after Christof's
suggestion (to enable the PDINSTANCE flag) but node-gyp
was the first wall I was still hitting.<br class="">
It seems there are still some slight updates I need to do
in the addon's code (I got some char * vs const char *
error).<br class="">
Your 3rd point makes obvious sense and I'll try this in
the first place today.<br class="">

<div class="">A few things:</div>
<div class=""><br class="">
</div>
<div class="">1. libpd does not use any paths, settings,
audio/midi backends, etc from desktop pd. It is
only the core and less than "pd without the
gui." This is by design as it makes no
assumptions about the environment since it can
be running in all manner of places. This means
it will only search paths relative to an opened
patch and those added explicitly by
llibpd_add_to_search_path().</div>
<div dir="ltr" class=""><br class="">
</div>
<div class="">2. Loading an external, whether it was
compiled against 0.47 or 0.49 should work as,
largely, the pd API has not changed that much.</div>
<div class=""><br class="">
</div>
<div class="">3. libpd needs to be built with -DHAVE_LIBDL
in order to be able to load separate,
precompiled externals.</div>
<div class=""><br class="">
</div>
<div class="">4. Some environments do *not* allow loading
dynamic libraries for legal/security reasons,
ie. iOS. I don't this is the problem, but it's
good to know...</div>

Mmmh you might have found the clue ...<br class="">
Actually I built the externals against pd
version 0.49-0 and it makes <br class="">
sense that they load properly with the same
version.<br class="">
node-libpd comes with an arm libpd binary
which seems to come from an <br class="">
older version of pd (added 1 year ago).<br class="">
I can already tell that it's not an
architecture issue because <br class="">
everything is working on my pi : the addon is
loading and running <br class="">
abstractions when used in a node program, and
pd is loading and running <br class="">
my externals.<br class="">
Only loading my externals from node-libpd
doesn't work.<br class="">
Still trying to get a local version of
node-libpd to work ... then I'll <br class="">
replace the libpd.so with one that I'll build
from the latest version.<br class="">
I can't see another explanation.<br class="">
Do you know something about incompatibilities
between different versions <br class="">
of pd ?<br class="">
The libpd.so used by the addon is probably not
older than 0.47<br class="">
