D compiler and phobos/object.d are mismatched?

Posted: 04/03/07 14:32:19 Hi, I tried Tango 0.96b2 a little bit with dmd.1.010/win32 in the last couple of days and found something strange. Tango works OK unless I define a class in my source code. If I do, the compiler stops at the line saying class CClass with the error message: class [source file name].[class name] D compiler and phobos/object.d are mismatched I first thought it was some kind of incompatibility of the binary distribution of tango and the current version of dmd, so I started over with a freshly installed dmd and dm and the source distribution of tango, but when I run build-dmd.bat, I get dmd -c -release -O -inline -w genobj.d -ofgenobj.obj genobj.d(83): class object.Object D compiler and phobos/object.d are mismatched genobj.d(237): class object.ClassInfo? D compiler and phobos/object.d are mismatched genobj.d(274): class object.TypeInfo? D compiler and phobos/object.d are mismatched genobj.d(344): class object.TypeInfo?_Typedef D compiler and phobos/object.d are mismatched genobj.d(373): class object.TypeInfo?_Enum D compiler and phobos/object.d are mismatched genobj.d(377): class object.TypeInfo?_Pointer D compiler and phobos/object.d are mismatched genobj.d(422): class object.TypeInfo?_Array D compiler and phobos/object.d are mismatched (...) This obviously is no common problem. If I enter the bug message into Google, I get two matches (unfortunately both in Japanese, so I don't understand). Has anybody any idea what's going wrong? Best regards, Dr_Vitus

At the very least, this happens if you have DMD 1.010 installed, along with the Tango Beta 2 installer. I reverted my DMD installation to 1.009 and re-ran the Tango installer. That seemed to do the trick. If it helps, you can find older DMD releases on the digitalmars FTP server: ftp://ftp.digitalmars.com/dmd.1.009.zip -- EricAnderton at yahoo

The runtime must also correspond to this size. With the changes from 1.009 to 1.010, a "defaultConstructor" field was added to ClassInfo?. This caused any runtime to become incompatible with the compiler. Personally, I think this is a design flaw.
