[BEACON] Cannot load shared library dllstdint_stubs when running compile_networks.py #226

Closed whcjimmy closed 2 weeks ago

whcjimmy commented 3 weeks ago

Hi there,

I'm trying to run the code from Secure Floating-Point Training which is in the Beacon directory. However, I got an error regarding a shared library is missing.

I tried pulling docker image from docker hub and building image with dockerfile by myself. However, both ways hit this issues in the end.

Is there any way to solve this problem? Thanks a lot.

This problem can be solved by

  1. clone ocaml library from https://github.com/ocaml/ocaml
  2. add the installed library to LD_LIBRARY_PATH
