From: Drew on 30 Jun 2006 15:44 I recently rewrote some code to compile and link on VS2005 from VS6, call it version 1 of the program. It now compiles and links under both VS6 and VS2005. I then branched this code to version 2 and now get errors in version 2 under VS6: D:\Program Files\Microsoft Visual Studio\VC98\Include\new(34) : error C2732: linkage specification contradicts earlier specification for 'delete' D:\Program Files\Microsoft Visual Studio\VC98\Include\new(34) : see declaration of 'delete' D:\Program Files\Microsoft Visual Studio\VC98\Include\new(35) : error C2732: linkage specification contradicts earlier specification for 'new' D:\Program Files\Microsoft Visual Studio\VC98\Include\new(35) : see declaration of 'new' D:\Program Files\Microsoft Visual Studio\VC98\Include\new(42) : error C2733: second C linkage of overloaded function 'new' not allowed D:\Program Files\Microsoft Visual Studio\VC98\Include\new(41) : see declaration of 'new' D:\Program Files\Microsoft Visual Studio\VC98\Include\wchar.h(700) : error C2733: second C linkage of overloaded function 'wmemchr' not allowed D:\Program Files\Microsoft Visual Studio\VC98\Include\wchar.h(699) : see declaration of 'wmemchr' D:\Program Files\Microsoft Visual Studio\VC98\Include\wchar.h(702) : error C2733: second C linkage of overloaded function 'wcschr' not allowed D:\Program Files\Microsoft Visual Studio\VC98\Include\wchar.h(701) : see declaration of 'wcschr' D:\Program Files\Microsoft Visual Studio\VC98\Include\wchar.h(704) : error C2733: second C linkage of overloaded function 'wcspbrk' not allowed D:\Program Files\Microsoft Visual Studio\VC98\Include\wchar.h(703) : see declaration of 'wcspbrk' D:\Program Files\Microsoft Visual Studio\VC98\Include\wchar.h(706) : error C2733: second C linkage of overloaded function 'wcsrchr' not allowed D:\Program Files\Microsoft Visual Studio\VC98\Include\wchar.h(705) : see declaration of 'wcsrchr' D:\Program Files\Microsoft Visual Studio\VC98\Include\wchar.h(708) : error C2733: second C linkage of overloaded function 'wcsstr' not allowed D:\Program Files\Microsoft Visual Studio\VC98\Include\wchar.h(707) : see declaration of 'wcsstr' D:\Program Files\Microsoft Visual Studio\VC98\Include\iosfwd(24) : error C2894: templates cannot be declared to have 'C' linkage D:\Program Files\Microsoft Visual Studio\VC98\Include\iosfwd(71) : error C2894: templates cannot be declared to have 'C' linkage D:\Program Files\Microsoft Visual Studio\VC98\Include\iosfwd(76) : error C2894: templates cannot be declared to have 'C' linkage D:\Program Files\Microsoft Visual Studio\VC98\Include\iosfwd(215) : error C2894: templates cannot be declared to have 'C' linkage D:\Program Files\Microsoft Visual Studio\VC98\Include\iosfwd(218) : error C2894: templates cannot be declared to have 'C' linkage D:\Program Files\Microsoft Visual Studio\VC98\Include\iosfwd(220) : error C2894: templates cannot be declared to have 'C' linkage D:\Program Files\Microsoft Visual Studio\VC98\Include\iosfwd(222) : error C2894: templates cannot be declared to have 'C' linkage D:\Program Files\Microsoft Visual Studio\VC98\Include\iosfwd(224) : error C2894: templates cannot be declared to have 'C' linkage D:\Program Files\Microsoft Visual Studio\VC98\Include\iosfwd(226) : error C2894: templates cannot be declared to have 'C' linkage D:\Program Files\Microsoft Visual Studio\VC98\Include\iosfwd(228) : error C2894: templates cannot be declared to have 'C' linkage etc. etc. etc. I have verified that the offending file and the project file are identical (I copied from version 1).

Yes. It was included indirectly in a nested header of a nested header in an extern "C" block. Thanks Igor.
