Some symbols in libprotoc's public API are hidden #12618
Description
What version of protobuf and what language are you using?
Version: v22.3
Language: C++
What operating system (Linux, Windows, ...) and version?
Linux. Tested with Fedora 37, but I think the problem is more general.
What runtime / compiler are you using (e.g., python version or gcc version)
GCC 12.2. I expect the problem is more general.
What did you do?
I am attaching a Dockerfile, you can run the test using:
docker buildx build -<DockerfileWhat did you expect to see
I expected the program to link successfully.
What did you see instead?
