Bug Description

So somewhen in last week there were made some changes in the ubuntu repository which effect libEGL. This lib newly uses libmirclient.so.9 which itself uses libprotobuf-lite.so.9. The default protobuffers version shipped with ubuntu is 2.6.1. My application uses libgstvaapi which uses libEGL. My application as well uses protobuffers but I link it statically to version 3.0.0 due to its json compatibility. So when now starting the application it crashes immediately due to rivaling protobuffers version. This problem first occured last week somewhen. This makes it impossible to use libEGL/libmir and a not-default protobuffers version in one application. Please let me how you're going to deal with that.

Best,
Henning

thats the error msg i get when i start my application

This program was compiled against version 2.6.1 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.0.0). 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. (Version verification failed in "/build/mir-ui6vjS/mir-0.26.3+16.04.20170605/obj-x86_64-linux-gnu/src/protobuf/mir_protobuf.pb.cc".)

Thanks.

This is an old issue. It used to cause problems with Unity8 too (see bug 1535297).

A proper fix needs to come from protobuf itself, but the bug could also be avoided if Mir or your app were willing and able to change protobuf versions.
