Protobuf lib conflicted mit system protobuf lib [ubuntu 16.04] #78

Closed fabolhak closed 7 years ago

fabolhak commented 7 years ago

Hey,

ich wollte gerade mal die nette Anleitung ausprobieren. Leider funktioniert der conan install Schritt bei mir nicht ganz (beim Linken der lms executable):

liblmscore.so: undefined reference to `google::protobuf::internal::empty_string_'
liblmscore.so: undefined reference to `google::protobuf::internal::WireFormatLite::ReadString(google::protobuf::io::CodedInputStream*, std::string*)'
liblmscore.so: undefined reference to `pugi::xml_node::path(char) const'
liblmscore.so: undefined reference to `google::protobuf::DescriptorPool::FindFileByName(std::string const&) const'
liblmscore.so: undefined reference to `google::protobuf::internal::WireFormatLite::WriteString(int, std::string const&, google::protobuf::io::CodedOutputStream*)'
liblmscore.so: undefined reference to `google::protobuf::Message::InitializationErrorString() const'
liblmscore.so: undefined reference to `google::protobuf::internal::StringTypeHandlerBase::Delete(std::string*)'
liblmscore.so: undefined reference to `google::protobuf::MessageFactory::InternalRegisterGeneratedFile(char const*, void (*)(std::string const&))'
liblmscore.so: undefined reference to `google::protobuf::internal::WireFormatLite::WriteStringMaybeAliased(int, std::string const&, google::protobuf::io::CodedOutputStream*)'
liblmscore.so: undefined reference to `google::protobuf::internal::StringTypeHandlerBase::New()'
liblmscore.so: undefined reference to `google::protobuf::io::CodedOutputStream::WriteStringWithSizeToArray(std::string const&, unsigned char*)'
liblmscore.so: undefined reference to `google::protobuf::Message::GetTypeName() const'

Anscheinend gibt es da wohl Probleme mit der Protobuf Lib die schon im System installiert ist: https://github.com/BVLC/caffe/issues/3046

Ich kann leider auch nicht die System Protobuf lib deinstallieren, da sich dann mein halbes Ubuntu mit deinstalliert (und nein ich würde nur sehr ungern irgendwelche Libs auf gut Glück löschen).

Auf meinem System sind die folgenden Protobuf Libs installiert:

Hattet ihr das Problem auch schon mal?

Ja, das Problem hatten wir am Samstag auf dem Intel NUC. Hat was mit Conan zu tun.

Phibedy commented 7 years ago

Das liegt daran, das die libs wahrscheinlich nicht kompatibel zum Compiler sind. Was für einen gcc verwendest du?
