`protobuf::json::PrintOptions.always_print_primitive_field` was deprecated and was removed from the current release

[E1k3]

Openeb does not compile with current protobuf. always_print_primitive_field probably has to be replaced with always_print_without_presence_fields or just removed depending on if you use proto2 or proto3 types. See https://github.com/protocolbuffers/protobuf/pull/15674 for deprecation and https://github.com/protocolbuffers/protobuf/issues/2871 for background.

Also this may already be mentioned in the currently open PR https://github.com/prophesee-ai/openeb/pull/123#discussion_r1647092993

Hi E1k3,

Yes, looks like you are correct, starting with protobuf v26.0 the field appears to have been renamed. I opened an issue on protobuf side so they would update their online documentation.

Waiting for the PR https://github.com/prophesee-ai/openeb/pull/123 to get merged, perhaps this patch will unblock you and other users facing this issue:
