::PROTOBUF_NAMESPACE_ID::internal::DescriptorTable descriptor_table_***_2eproto

[KaimingGao]

version : 3.8.0

compile command:
protoc --cpp_out=./ google/protobuf/descriptor.proto -Igoogle/protobuf

then I got descriptor.pb.h. Howerver, this pb.h is different with the original google/protobuf/descriptor.pb.h.

e.g. I got：

extern const ::PROTOBUF_NAMESPACE_ID::internal::DescriptorTable descriptor_table_descriptor_2eproto;

in my file.

while in the original file, it is:

extern PROTOBUF_EXPORT const ::PROTOBUF_NAMESPACE_ID::internal::DescriptorTable descriptor_table_google_2fprotobuf_2fdescriptor_2eproto;

so, how to compile the descriptor.proto to get the right pb.h ?

by the way, I got a similar issue with

descriptor_table_proto_2fcommon_2eproto #6179 #6179

The compiler output is sensitive to filename of the input.

So compiling google/protobuf/descriptor.proto will give different output than compiling just descriptor.proto, even if the file contents are identical.

So if you want to get the same output as the original, run:

protoc --cpp_out=. google/protobuf/descriptor.proto

(ie omit the -I).
