使用Ubuntu16.04和cmake,我试图从protobuf文件创建一个共享库。cmakes protobuf_generate_cpp正在生成proto_srcs和proto_hdrs。
我的系统中没有任何google/protobuf/*.proto文件,所以我下载了3.6.1并将其移动到/usr/local/include中。我知道我使用的是proto2,protoc是版本2,3.6.1中的一些*.proto文件是proto3,但是下面的文件(我使用的是syntax=“proto2”),所以我认为应该可以。
但是,我遇到了以下错误。
$ protoc --version
libprotoc 2.6.1

有人有想法吗?
