It sure looks like |vst_cleanser.o never made it into libpd, despite the
extra arg to the makefile... perhaps because the Makefile isn't recent
enough (in which case you won't see the string MORESRC in the Makefile
in [...]/libpd ). You can get the very latest this way: git clone
g...@github.com:pure-data/pure-data.git (or if you don't want to deal
with git, just point your browser there and look under the code button
for a zip archive.) BUT... I still don't know why libpd.a is showing
s_signal undefined - all the sources should be compiled with PDINSTANCE
in which case s_signal isn't referenced anywhere. If some of those
object files are looking for s_signal Iwould expect pureVST to crash
when a patch gets loaded. You'll get a lot of output but if you try "nm
*.o" and fish for s_signal you might find the offending object files. I
have no idea how they could be getting compiled that way. thanks Miller |

I've been trying to figure out how that could happen without

sp@bang:~/pd/libpd$ nm libpd.a |grep s_sig

I get the following:
```
U s_signal
U s_signal

U s_signal

so I guess the symbol is missing. I tried deleting everything in the
libpd directory (apart from the Makefile, README and the test_libpd
directory) and to re-build it with
`|make MORECFLAGS=-DVST_CLEANSER
MORESRC=[...path-to...]/PureVST/source/vst_cleanser.c|`
but the result is the same
... so libpd.a is defining the (apparently missing) symbol. If yours
is missing, then somehow the libpd.a build
missed including vst_cleanser.c from the pureVST source. But if
yours is present like mine is (which I expect you
to find) then something about the linker command is funny. You could
then run "cmake --build . --verbose" so that
we could both look at how the linker is getting invoked on our
respective systems.
Meanwihle... in trying to recompile everything from scratch I now get
a problem further down the line (a segfault trying to run
Steinberg's 'validator'.) I had to start all over and add
-DSMTG_RUN_VST_VALIDATOR=FALSE to the cmake command -
then, unexpectedly, I was able to load the plugin under ardour and
all seemed fine. But something seems to be pretty
fragile here :)

It could be that as you looked at the README you saw the 'cmake
-DCMAKE_BUILD_TYPE=Release...' command broken into two lines -
I should find a way to prevent that from happening :)

OK, I downloaded PureVST (sorry, had to figure this out earlier)

I also corrected the paths to the VST3 SDK and Pd's source (well,
Pd's directory that includes the src/ directory, not the actual
src/ directory; that's what I got I should do from the
CMakeLists.txt file) and I run:
`cmake -DCMAKE_BUILD_TYPE=Release`

Perhaps something is missing in the command, like a double dot? I
know nothing about CMake, so this could be rather trivial...

Hmm... the directions could have been clearer, sorry....
vst_cleanser.c is in the pureVTS source, not in the Pd source. If
you've downloaded and unpacked the PureVST source tarball it
should be just "purevst/source/vst_cleanser.c". And yes, no
trailing period (I think my markdown-to-html converter remove the
space I had put between the filename and the period).
and yes, 'wherever the sources landed" refers to the pureVST
source (currently
https://msp.ucsd.edu/tools/purevst/PureVST-0.5.src.tgz ) whic
need dwonloading and unpacking before even making this version of
libpd.

I'm trying to compile pureVST from source on Debian 12. I built
the VST SDK and following pureVST's README, I've gone up to the
following step `make MORECFLAGS=-DVST_CLEANSER` insinde the
libpd directory.
I don't quite understand the following steps. Right after this,
the README reads that I should type
`MORESRC=../../work/vst/purevst/source/vst_cleanser.c.`
Being inside the libpd directory, where will the two parent
directories lead me, since the path starts with ../../? Also,
where is this `work` directory supposed to be? Or `vst` and
`purevst`? Are these directories Miller created in his system?
I did a `find . -name vst_cleanser.c` from my home directory and
found nothing (BTW, is the dot at the end supposed to be there?).
Then the instructions follow like this:
```
Then using the PureVST source tree, consult the CMakeLists.txt
file and correct the path settings for the VST SDK and for the
Pd source. Then make an empty build directory, and using a shell
or terminal window, change directory to the build directory and
try to get these to work in sequence:
|SRC=~/work/vst/purevst|
[… or wherever the sources landed]
|cmake -DCMAKE_BUILD_TYPE=Release
-DSMTG_ENABLE_VST3_PLUGIN_EXAMPLES=FALSE
-DSMTG_ENABLE_VST3_HOSTING_EXAMPLES=FALSE -DHOME=$HOME $SRC|
|cmake --build .|
```
It mentions "or wherever the sources landed". Which sources?
After building libpd? And in which directory should all the
cmake command be executed?
