关于promessage的问题

bluevincent

vc总是抱错，参照修改方法中写了个宏
#define PRO_USE_VAR_ARGS
  
extern ProError ProMessageDisplay(
#ifdef PRO_USE_VAR_ARGS
          ProFileName file_name,  
          ProCharLine message_name
#endif
);
编译通过了，但是link 的时候却出了问题
LINK : warning LNK4098: defaultlib "LIBCD" conflicts with use of other libs; use /NODEFAULTLIB:library
wild.obj : error LNK2001: unresolved external symbol "enum ProErrors __cdecl ProMessageDisplay(unsigned short * const,char * const)" (?ProMessageDisplay@@YA?AW4ProErrors@@QAGQAD@Z)
Debug/wild.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
