Yes, it's from the latest version of your repo. I did a "make clean" and a new "make" and still get the same. It's very strange. In the Makefile the /usr/local/lib path is specified, but Pd keeps on complaining.

Don't know if this is of any relevance, but "file /usr/local/lib/libfann.so.2" says that this is a symbolic link to /usr/local/lib/libfann.so.2.2.0, which in turn is an ELF 64-bit LSB shared object.

Just to confirm, did you pull my latest change to the repo with a new Makefile, do a "make clean", and then a new "make"?

I did "make fann_static" in fann's directory which gave this output "[100%] Built target fann_static" and then "sudo make install" and then "make" in pd_fann directory, but I keep on getting the same error message when trying to load the object in Pd. My system is UbuntuStudio 21.10 with Pd-0.52.2 compiled from source.

Ok - I just updated the repo so the project is using pd-lib-builder. I'm on my Ubuntu 20.04.4 LTS machine now and the [fann] external builds and loads fine for me. When building the actual FANN library, make sure to build it as static with "make fann_static". Then do "make install" so the lib and headers get to /usr/local. After that, you should be able to build the Pd [fann] external with just "make".

I managed to build it on Linux but again can't load it, getting this error:

/home/alexandros/Documents/Pd/externals/pd_fann/fann.pd_linux: libfann.so.2: cannot open shared object file: No such file or directory

even though there is a libfann.so.2 file in /usr/local/lib, as I have built FANN 2.2.0. Is there something I need to change in the source?

I got into this a few years ago and updated/extended the [ann_mlp] object. Here's the repo: https://github.com/wbrent/pd_fann. I just tried building it against the latest version of FANN (2.2.0) and it still appears to work fine. I need to update the project to use pd-lib-builder, but the included Makefile works for x86_64 builds on Mac.

I could be wrong, but I don't believe anyone has taken over maintenance of [ann]. The original sources are still in the SVN export to git.puredata.info:

http://git.puredata.info/cgit/svn2git/libraries/ann.git/

If there is interest, we could push this to the pd-externals group on GitHub, add pd-lib-builder support, then someone can take over maintenance. You perhaps? :)

I run into [ann] in Pd's website
(http://puredata.info/Members/dmorelli/ann/ann/) from the Fann homepage
and downloaded the Linux version, but it's a 32-bit build and Pd can't
load it. I can't find it in deken. Anyone (IOhannes maybe, since you
have provided the Linux build) has the source code so I can try to
compile (any compilation instructions would be great too).

Thanks,
Alexandros
