// This is just a compile test (here to make sure things never regress).
//
// Objective C++ can run into issues with how the NS_ENUM/CF_ENUM declaration
// works because of the C++ spec being used for that compilation unit. So
// the fact that these imports all work without errors/warning means things
// are still good.
//
// The "well know types" should have cross file enums needing imports.
#import "GPBProtocolBuffers.h"
// Some of the tests explicitly use cross file enums also.
#import "google/protobuf/Unittest.pbobjc.h"
#import "google/protobuf/UnittestImport.pbobjc.h"

// Sanity check the conditions of the test within the Xcode project.
#if !__cplusplus
  #error This isn't compiled as Objective C++?
#elif __cplusplus >= 201103L
  // If this trips, it means the Xcode default might have change (or someone
  // edited the testing project) and it might be time to revisit the GPB_ENUM
  // define in GPBBootstrap.h.
  #warning Did the Xcode default for C++ spec change?
