load_object: Symbol "nn_tilde_setup" not found

[interperipheral]

On Windows 10 with Pure Data Vanilla "load_object: Symbol "nn_tilde_setup" not found" shows up and the nn~ object can't be created. I followed the install directions in the readme. Am I doing something wrong?

[interperipheral]

Nothing changed. on ver 1.5.5. I'm open to this being user error on my part but I have no idea what I could've done wrong

[caillonantoine]

Have you tried compiling nn~ yourself ?

[interperipheral]

cmake ..\src -A x64 -DCMAKES_PREFIX_PATH="C:\libtorch" -DPUREDATA_BIN_DIR="C:\Program Files\Pd\src" -DPUREDATA_BIN_DIR="C:\Program Files\Pd\bin"

CMake Error at backend/CMakeLists.txt:4 (find_package):

  the following names:

I've barely used CMake and never done anything with Libtorch so I'm not entirely sure what all the terminology here means. Adding C:\libtorch\cmake\Torch to the CMAKE_PREFIX_PATH environment var didn't change anything

Download libtorch and unzip it somewhere on your computer (but maybe not directly in c:), somewhere in the downloads folder should be fine. Then you can build the project using

cmake ..\src -A x64 -DCMAKE_PREFIX_PATH="C:\Users\XXX\Downloads\libtorch"
cmake --build . --config Release

[interperipheral]

The location of libtorch didn't have anything to do with it, I also downloaded the right .zip specified in the readme. The real problem is that one of the flags was misspelled and I didn't notice. I wasn't paying attention, sorry about that. additionally I typed DPUREDATA_BIN_DIR twice instead of DPUREDATA_INCLUDE_DIR, and because of that I would've only built files for Max/MSP.

Building from source seemed to have solved the issue

Glad to hear it :)
