Is it possible to have multiple versions of protobuf?

[josh-wende]

Hi,

I am trying to bring in an external library that requires an older version of protobuf than the one already in apollo. As such, I have been trying to get apollo to contain two different versions of protobuf, with the older one only used for this new build target. I got bazel building this version of protobuf (3.6.1) inside of the apollo container, and then I made that a dependency of the new code that uses the external library.

But when I try to run it, I get this error:

This program was compiled against version 3.6.1 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.19.6).  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 "google/protobuf/any.pb.cc".)
Aborted (core dumped)

Is there a correct way to do this that I'm missing? I'd really appreciate any insight.

I had a mistake in my BUILD files. As long as I keep the dependencies completely separate, it seems to work.
