EPEL 6 contains `protobuf-2.3.0` EPEL 7 contains `protobuf-2.5.0` Fedora 29 contains `protobuf-3.5.0`
On `CentOS 6` we have `libphonenum` compilation error ``` [ 117s] /usr/include/google/protobuf/repeated_field.h: In function 'i18n::phonenumbers::PhoneNumberUtil::ValidationResult i18n::phonenumbers::<unnamed>::TestNumberLength(const std::string&, const i18n::phonenumbers::PhoneMetadata&, i18n::phonenumbers::PhoneNumberUtil::PhoneNumberType)': [ 117s] /usr/include/google/protobuf/repeated_field.h:130: error: 'google::protobuf::RepeatedField<Element>::RepeatedField(const google::protobuf::RepeatedField<Element>&) [with Element = int]' is private [ 117s] /home/abuild/rpmbuild/BUILD/libphonenumber-8.10.6/cpp/src/phonenumbers/phonenumberutil.cc:334: error: within this context [ 117s] /usr/include/google/protobuf/repeated_field.h:130: error: 'google::protobuf::RepeatedField<Element>::RepeatedField(const google::protobuf::RepeatedField<Element>&) [with Element = int]' is private [ 117s] /home/abuild/rpmbuild/BUILD/libphonenumber-8.10.6/cpp/src/phonenumbers/phonenumberutil.cc:336: error: within this context [ 117s] /usr/include/google/protobuf/repeated_field.h:130: error: 'void google::protobuf::RepeatedField<Element>::operator=(const google::protobuf::RepeatedField<Element>&) [with Element = int]' is private [ 117s] /home/abuild/rpmbuild/BUILD/libphonenumber-8.10.6/cpp/src/phonenumbers/phonenumberutil.cc:359: error: within this context ``` If you can find 'libphonenum' that works on `CentOS 6` and also can be compiled on `Fedora 29` then i can add this version to OBS repo.
