Package Mandatory ?

[Julien PONNOU]

Hello,

When I include several couples of .h/.cc in my project, I got the
following errors during the compilation:

error C2086: 'google::protobuf::ProtobufOnceType `anonymous-
namespace'::protobuf_AssignDescriptors_once_' : redefinition
see declaration of '`anonymous-
namespace'::protobuf_AssignDescriptors_once_'
error C2084: function 'void `anonymous-
namespace'::protobuf_AssignDescriptorsOnce(void)' already has a body
see previous definition of 'protobuf_AssignDescriptorsOnce'
error C2084: function 'void `anonymous-
namespace'::protobuf_RegisterTypes(const std::string &)' already has a
body
see previous definition of 'protobuf_RegisterTypes'

Basically, it's telling me these functions are declared in all couples
of .h/.cc. Using a different package for each couple of .h/.cc
corrects the problem, but I don't want to do so. Without using any
package, can someone explain me how to solve this error ?

Best regards,

Julien.

The function name is determined by the source proto file path. Looks like you always generate messages from a single .proto file. You would have to generate the message in different files. Otherwise, even if you worked around the function name issue, the runtime DescriptorPool would complained about duplicated file descriptors.
