has no member named ‘usize’; did you mean ‘size’? #23

hi~ I successfully installed libOTe, but I got the following error when compiling libPSI, what should I do?

Yes, cryptoTools has been updated and removed usize. I'll try to fix this soon but in the meantime you can either roll back the commit of libOTe (maybe v1.51 works) or change usize() to size()

ladnir commented 2 years ago

ok, fixed. The new setup is:

git clone https://github.com/osu-crypto/libPSI.git
cd libPSI
python build.py

This will now download the correct version of libOTe to thirdparty/libOTe and locally install to out/install/<platform>/. Hopefully installing libPSI should also work but i didnt test it . Let me know if you have questions.

I have no more questions, thanks
