when I go to SocketAdapter.h:166 I don't see the offending line of code. Is this code you wrote?

[locomotive-crypto]

No, I don't do anything.

[ladnir]

well not sure how to help you. That line of code is not in the repo https://github.com/ladnir/cryptoTools/search?q=error+%3D+%28ec+%21%3D+0%29%3B

Thanks, It may be the problem about other libraries. I use this library as the third-party library for compiling the secure-kmean-clustering: https://github.com/osu-crypto/secure-kmean-clustering
