https://issues.dlang.org/show_bug.cgi?id=22315 Issue ID: 22315 Summary: ImportC: #pragma pack is not implemented Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: dave287091 gmail.com I believe Walter has said that he doesn’t intend to support #pragma pack, but I have discovered some macOS system headers that use the feature. At least, fcntl.h and sys/event.h use the feature in defining some structures. An example from event.h: #pragma pack(4) struct kevent { uintptr_t ident; /* identifier for this event */ int16_t filter; /* filter for event */ uint16_t flags; /* general flags */ uint32_t fflags; /* filter-specific flags */ intptr_t data; /* filter-specific data */ void *udata; /* opaque user data identifier */ }; #pragma pack() (I have no idea why pragma pack is even used here, the structure has no padding). I haven’t studied the headers closely enough to see if ignoring it matters or not. --
