Failing to build Perfetto protobuf schemas

[zmitchell]

Hey, this could absolutely be user error, but I'm getting these errors trying to build bindings for the Perfetto protobuf schemas:

Failed to parse file /home/zmitchell/.cache/zig/p/N-V-__8AACqpdQYd8TVO_tA8wrl-fF2G7rPfP9Xdt5dZ5I_O/protos/third_party/chromium/optimization_guide/actions_data.proto [offset = 1035]:

The source is here for those protobuf schemas: https://github.com/google/perfetto/tree/v53.0/protos

This is what my ProtoGenStep looks like:

const proto_gen_step = ProtoGenStep.create(b, .{
    .name = "protobuf",
    .proto_sources = perfetto_src.path("protos"),
    .target = b.path("src/gen"),
});
