Hi,dear some errors occurred when building PrivacyGuard:

and version of SGX SDK is 2.3.1 , rather than 2.0.1 in readme? 图片

Yes there should be a libsvm.a file in the repo but somehow it was not accepted to github. Can you comment out these two libs (and in related .cpp files) for the time being, and try the neural network (fann) option? I think we tried both versions in the experiment. v2.3.1 should work too.

Yeah，it works，thanks very much！
