Hi, I got this snippet of code that bombs out during linking.... if is from https://github.com/ceph/ceph/blob/master/src/rgw/rgw_file.h#L805 /* find or create an RGWFileHandle */ LookupFHResult lookup_fh(RGWFileHandle* parent, const char *name, const uint32_t flags = RGWFileHandle::FLAG_NONE) { using std::get; // This seems like a Clang compiler error. // It result in irgw::RGWFileHandle::FLAG_NONE being undefined during linking. // LookupFHResult fhr { nullptr, RGWFileHandle::FLAG_NONE }; LookupFHResult fhr { nullptr, 0 }; And the complaint in the end during linking that rgw:RGWFileHandle::FLAG_NONE is unknown. But as far as I know it is defined on line 255 in the same file. And even stranger.... 2 lines back there is also a reference to that same variable. Now the only modification I have to do is replace RGWFileHandle::FLAG_NONE on that last line of the snippet to get things going again. And note that references to the other defined vars around line 255 do not suffer from the same problem. Can anybody explain to me what I'm missing? Thanx, --WjW
