# protobuf/cfg - "Build" settings for package

#---------------------------------------------------------------------

[technotes]

1. The source tarball used by this  package was created based on "git"
upstream sources. The following command was used:

      ocgitfetch --run \
--checkout=v3.25.8 \
--deletegit \
https://github.com/protocolbuffers/protobuf.git

#---------------------------------------------------------------------

2. This part is tricky:

The releases of "abseil", "protobuf", and "protobuf-c" used need to be
selected  so as to be compatible with each other as well as with other
packages that depend on them.

As of Fall 2025,  we weren't able to build "protobuf" 4.25.X using ei-
ther "gcc" or "clang". This might or might not have been due to a con-
flict with the release of "abseil" used at the time.
