"sudo ldconfig" did the trick! Now the object loads and works fine, thanks!

Try running "sudo ldconfig" and see if that resolves it. If not, do a sanity check by copying libfann.so.2.2.0 to the fann directory and make a libfann.so.2 symlink to it there. It's a temporary hack, but if you do that it really should load properly in Pd. If even that doesn't work, I'm stumped!On Mon, Apr 11, 2022 at 2:19 PM Alexandros <[email protected]> wrote: 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.

My system is UbuntuStudio 21.10 with Pd-0.52.2 compiled from source. On 11/4/22 17:49, William Brent wrote: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".

Is there something I need to change in the source? On 11/4/22 16:39, William Brent wrote: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.

The original sources are still in the SVN export to git.puredata.info <http://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.

Message-ID: <[email protected]> Content-Type: text/plain; charset=UTF-8; format=flowed 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).
