Summary: bitfields and Typedef don't mix Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: nob...@puremagic.com ReportedBy: andrej.mitrov...@gmail.com --- Comment #0 from Andrej Mitrovic <andrej.mitrov...@gmail.com> 2012-09-13 20:33:42 PDT --- import std.typecons; import std.bitmanip; static import core.stdc.config; alias Typedef!(core.stdc.config.c_ulong) c_ulong; struct Foo { mixin(bitfields!( c_ulong, "NameOffset", 31, c_ulong, "NameIsString", 1 )); } void main() { } It's great to see we've deprecated typedef for a library solution that doesn't work. :\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(77): Error: Cannot interpret Typedef!(uint,0u) at compile time D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(77): Error: expression (Typedef!(uint,0u)).opDispatch() < 0u is not constant or does not evaluate to a bool D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(111): Error: Cannot interpret Typedef!(uint,0u) at compile time D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(159): Error: template instance std.bitmanip.createAccessors!("_NameOffset_NameIsString",Typedef!(uint,0u),"NameOffset",31,0u) error instantiating D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(213): instantiated from here: createFields!("_NameOffset_NameIsString",0,Typedef!(uint,0u),"NameOffset",31,Typedef!(uint,0u),"NameIsString",1) test.d(11): instantiated from here: bitfields!(Typedef!(uint,0u),"NameOffset",31,Typedef!(uint,0u),"NameIsString",1) D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(77): Error: Cannot interpret Typedef!(uint,0u) at compile time D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(77): Error: expression (Typedef!(uint,0u)).opDispatch() < 0u is not constant or does not evaluate to a bool D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(111): Error: Cannot interpret Typedef!(uint,0u) at compile time D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(159): Error: template instance std.bitmanip.createAccessors!("_NameOffset_NameIsString",Typedef!(uint,0u),"NameIsString",1,31u) error instantiating D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(160): instantiated from here: createFields!("_NameOffset_NameIsString",31u,Typedef!(uint,0u),"NameIsString",1) D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(213): instantiated from here: createFields!("_NameOffset_NameIsString",0,Typedef!(uint,0u),"NameOffset",31,Typedef!(uint,0u),"NameIsString",1) test.d(11): instantiated from here: bitfields!(Typedef!(uint,0u),"NameOffset",31,Typedef!(uint,0u),"NameIsString",1) D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(160): Error: template instance std.bitmanip.createFields!("_NameOffset_NameIsString",31u,Typedef!(uint,0u),"NameIsString",1) error instantiating D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(213): instantiated from here: createFields!("_NameOffset_NameIsString",0,Typedef!(uint,0u),"NameOffset",31,Typedef!(uint,0u),"NameIsString",1) test.d(11): instantiated from here: bitfields!(Typedef!(uint,0u),"NameOffset",31,Typedef!(uint,0u),"NameIsString",1) D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(213): Error: template instance std.bitmanip.createFields!("_NameOffset_NameIsString",0,Typedef!(uint,0u),"NameOffset",31,Typedef!(uint,0u),"NameIsString",1) error instantiating test.d(11): instantiated from here: bitfields!(Typedef!(uint,0u),"NameOffset",31,Typedef!(uint,0u),"NameIsString",1) test.d(11): Error: template instance std.bitmanip.bitfields!(Typedef!(uint,0u),"NameOffset",31,Typedef!(uint,0u),"NameIsString",1) error instantiating -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
