Problems linking ACE in VC++

Question

Hi,

I've built ACE.dll and ACE.lib of the ACE library. But when I link it to my program, I get several errors like

Error 2 error LNK2019: unresolved external symbol "void * __cdecl ACE_OS::memcpy(void *,void const *,unsigned int)" (?memcpy@ACE_OS@@YAPAXPAXPBXI@Z) referenced in function "public: void __thiscall ACE_String_Base::set(char const *,unsigned int,bool)" (?set@?$ACE_String_Base@D@@QAEXPBDI_N@Z) client_handler.obj Server

Error 3 error LNK2001: unresolved external symbol "void * __cdecl ACE_OS::memcpy(void *,void const *,unsigned int)" (?memcpy@ACE_OS@@YAPAXPAXPBXI@Z) Server.obj

I've set include paths,lib paths, lib dependencies etc etc. I dont know what I'm missing :(

The linker is unable to find a definition for ACE_OS::memcpy. Check the documentation and see if you need to provide a suitable definition or not (or if there is one in the sample, if any samples are present at all).

This could also be because you've not defined a platform specific macro that would enable the default definition of this function. Please check the readme.
