You don't need to manually call protoc. Let's cmake generate files. Try again with last release tag. /cc @nyanp

[Randl]

@blakeliu Do you still have the issue?

[Randl]

No answer for a week, closing

I am sorry, I meet the same problem. (Need install something before?) @Randl @bhack (I do not open a new issue)

[edgarriba]

could you try with an old protobuf version ?

I met the same problem.
protoc version: libprotoc 3.6.0

[somekindsoffood]

met the same problem.
I have installed caffe successfully with protoc version 2.6.1.(if use other version it will throw this error)
but when I try to make this file it failed.And I had try different protoc version on 3.7.1 and 3.6.1 all failed.
Does someone know what going on here?
