Can't get Caffe to compile

I'm sure it's something simple, but the error I get is:

I am having the same compilation problem. Have you fixed it yet?

[J. Yegerlehner]

I don't know if this is happening in your particular case, but I saw similar problem a while back because I had the proto-generated caffe.pb.h file from an old build sitting around. So I would search the file system for that file, and see if you the compiler might be finding an old version of that file sitting around, which you'll want to delete. It sounds similar because the compiler doesn't think "BlobShape" is a type, and it is a proto-generated type.

In my case, I think the  Makefile build had put the caffe.pb.h someplace where the cmake build found it, and so cmake build was trying to include the old out-of-date caffe.pb.h.

[Dzung Nguyen]

Thanks, this is indeed the reason for compilation error!
