Conversion Error

[h4ck4t]

System: Windows10 IDE: Visual Studio 2022 Problem: When I try to compile the project, following problems show up, and I'm confused that mOtSender->recvCorrection method takes a Channel as input, while its definition is Socket.

You have the wrong version of libOTe. Did you install libOTe on your own?

Yeah. I tried python.py，but seems having difficulty cloning libote in my area. So I compiled manually.

Is there any version indication？

LibOTe v1.6 should also work but the link above has the currently tested git commit.

Thanks for suggestion. Now I found that libOTe being configured properly, but it's relic that makes things complex. The information is: Build

'C:/Program Files/CMake/bin/cmake.exe' '--build' 'C:/Users/ceezous/Desktop/libPSI-private/thirdparty/libOTe/cryptoTools/thirdparty/relic/build/x64-Release' '--config' 'Release'

CMake Error at cryptoTools/thirdparty/fetch.cmake:35 (message):

Build failed (1).

So libOTe is also going to pull in a bunch of things. Relic etc...

You will need to clone these manually as well. Or build the whole thing with internet and then move it off internet...
