problems building with dwgdirect 2.6.3
i've just upgraded our application from dwgdirect 2.2.0 to 2.6.3 and i now cannot seem to link
without errors.
when linking against debug 2.6.3 dwgdirect libraries and msvcrtd and mfc90ud i get:
msvcprtd.lib(msvcp90d.dll) : warning lnk4006: "public: __thiscall std::allocator
<char>::allocator<char>(void)" (??0?$allocator@d@std@@qae@xz) already defined in

when linking against nodebug 2.6.3 dwgdirect libraries and msvcrt and mfc90u i get:

system failed errno = 0
my locally compiled code (in cad_dwg.lib) is built debug (including exhostappservices.obj which is
built from the source file distributed with 2.6.3) in both cases.
the nodebug build used to work fine using the nodebug 2.2.0 dwgdirect libraries. in fact before 2.6.3 i used only the nodebug dwgdirect libraries to build all the time.
thanks in advance for any help anyone can provide,
barry
did you tried just delete ncb, clean/rebuild all?
