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>
It can't find the HAVE_LIBPD definition anywhere, though ... is this
normal ?<br>
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>
Or should it be added to the cflags with -DHAVE_LIBPD ?<br>
<br>
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>
they fail with an `undefined symbol` error, the undefined symbol
being `canvas_undo_undo`.<br>
Sounds familiar to anybody ?<br>
I have no idea how to solve this ...<br>
<br>
Thanks,<br>
Joseph<br>

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>
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>
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>
Your 3rd point makes obvious sense and I'll try this in the
first place today.<br>

<div>A few things:</div>
<div><br>
</div>
<div>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"><br>
</div>
<div>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><br>
</div>
<div>3. libpd needs to be built with -DHAVE_LIBDL in
order to be able to load separate, precompiled
externals.</div>
<div><br>
</div>
<div>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>

<div>I image you're issue is more to do with 3.</div>

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