run example_without_lib.js error: need 3.1.0 Protocol Buffer runtime library

[jiangzidong]

Hi I build the js according to #1 (in ubuntu, changing libprotobuf.a to libprotobuf.so)

And I run example_without_lib.js, and it reports error:

node example_without_lib.js
[libprotobuf FATAL google/protobuf/stubs/common.cc:68] This program requires version 3.1.0 of the Protocol Buffer runtime library, but the installed version is 3.0.0.  Please update your library.  If you compiled the program yourself, make sure that your headers are from the same version of Protocol Buffers as your link-time library.  (Version verification failed in "/home/dd/ml/tf-em/tensorflow/contrib/makefile_js/gen/proto/tensorflow/core/framework/kernel_def.pb.cc".)

Have you met the similar error before? the protoc in my host machine is 3.1.0, while in your protobuf-emscripten repo, the version seems 3.0.0. Am I right about it?

[tomasreimers]

Yup, seems that you are correct! Will update the repository soon (have one major push on this repo coming out very soon -- including documentation, and then I'll start addressing Ubuntu).

In the meanwhile, one fix might be to downgrade protoc, just to verify that it works.

Update my status in ubuntu:

After I upgrade the emscripten-protobuf from 3.0 to 3.1, there is no version error. But I got the following error:

$ node example_with_lib.js
