undefined reference to `Blowfish::Blowfish`

[zjbaby]

Hi, I compile follow the steps：

1. cd $CAFFE_ROOT
2. cp Makefile.config.example Makefile.config
3. uncomment the line: USE_CUDNN := 1
4. comment the *_20 and *_21 lines
5. make -j7

and I get errors like that: .build_release/tools/encrypt_model.o: In function main': encrypt_model.cpp:(.text.startup+0x79): undefined reference to Blowfish::Blowfish(std::vector<char, std::allocator

Why and how to fix it?

[makefile]

@zjbaby I can't directly think of what the problem is, it may be related to your compilation environment.Make a clean copy and try again later.
