protobuf version conflict

[czastack]

When I build finish and run face_swap_image --cfg test.cfg I got this error as bellow. [libprotobuf FATAL google/protobuf/stubs/common.cc:78] This program was compiled against version 2.6.1 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.3.0). Contact the program author for an update. If you compiled the program yourself, make sure that your headers are from the same version of Protocol Buffers as your link-time library.

I have remove the libprotobuf-dev and protobuf-compiler from system and rebuild all the dependencies. But it is the same. Can you give me some advice?

• Ubuntu 16.04
• Boost 1.58
• Qt 5.9
• OpenCV 3.2
• GLEW 2.0
• Eigen 3.0.0
• dlib 18
• find_face_landmarks 1.1
• face_segmentation 0.9
• Caffe 1.0

It seems you still have some residue of the previous version of protobuf. I would try to do the following:

• Make sure you remove all the old protobuf libraries and headers.
• Caffe or OpenCV might contain a local version of protobuf, configure them to use your latest protobuf version (3.3.0).
• Do a clean build and install of OpenCV, Caffe, find_face_landmarks, face_segmentation, and face_swap (in this order).

Good luck!

When I delete libprotobuf.so.9 and libprotobuf-lite.so.9, the ubuntu desktop crash. In addition, there is no protobuf 2 installed. And I don't know how to onfigure Caffe and OpenCV to use latest protobuf. The opencv-3.2.0 use the protobuf-3.1.0 from source.

I found this in internet.

The Mir version in any Ubuntu archive is built with the protobuf version in the archive. The version of protobuf in the Ubuntu 16.04 archive is 2.6.1.

The simplest option is to use libprotobuf-dev as supplied in the archive. If you need to use a more recent version, then you'll need to rebuild any packages that use it, including Mir.

Using a different archive won't help: Even the current 17.04 release only has 3.0.0 of protobuf.

I don't know how to do now.

Use CMake to configure the libraries to use the right version of protobuf. The cmake-gui application is especially useful for that.

You can install any version of protobuf you want, the Linux version doesn't matter. Just specify a different install directory instead of the default one.

same problem as well… and I did using cmake build and install in order... still failed :(

[YuvalNirkin]

There is no way for me to reproduce this problem :( If you get a runtime error as mentioned in the first comment, you can try setting the LD_LIBRARY_PATH environment variable with the path to the right protobuf version.

I am closing this issue. Feel free to open it again if you still have problems with this.
