网上有些说是protof编译的时候的gcc的版本以及说是protof可能系统自带了一个造成的冲突:
解决protobuf: undefined reference to `google::protobuf::internal::fixed_address_empty_string[abi:cxx11_undefined reference abi:cxx11-CSDN博客
不过我看了下我只装了一个版本的。
解决办法:
g++ test.cc contacts.pb.cc -o test_proto $(pkg-config --cflags --libs protobuf) -std=c++11 -lpthread
暂时这么解决了,demo不报错了,如果有更好的方法欢迎交流,因为我对linux这一块儿也是完全不熟。
