By hijacking this 14 // function, and calling InitGoogle, we can compile all the example 15 // code that ships with Ceres without any modifications. This 16 // modification will have no impact on google3 binaries using Ceres, 17 // as they will never call google::ParseCommandLineFlags. 18 19 #ifndef GFLAGS_GFLAGS_H_ 20 #define GFLAGS_GFLAGS_H_ 21 22 #include "base/init_google.h" 23 #include "base/commandlineflags.h" 24 25 namespace google { 26 27 inline void ParseCommandLineFlags(int* argc, 28 char*** argv, 29 const bool remove_flags) { 30 InitGoogle(**argv, argc, argv, remove_flags); 31 } 32 33 } // namespace google 34 35 #endif // GFLAGS_GFLAGS_H_ 36
