6 years ago Building this project and all it's dependencies is not easy I know. First of all the minimum version of Protobuf as required by sequence_face_landmarks is 3.0.0. I suggest you build all dependencies from source using CMake, make sure that you checkout stable releases and not the master branch (except for the face_swap project in which the master branch is preferable).
You can use the ldd command to understand where the linkage problems are coming from.
Good luck!
I had tried many ways to compile this project in Ubuntu14.04，but all failed at the last. I have no idea about how to compile it.
face_swap needs gcc5.0+ for supporting C++11/14 but my Caffe was compiled by gcc4.X，protobuf2.5 was installed from apt-get face_swap make failed when linking, about protobuf

then, I tried to compile Caffe and Protobuf-2.5 with gcc5.5 from source but Caffe was failed the same in linking
