Can anyone answer a question I have about creating libraries in C/C++? I am new to programming in Visual C++ and am trying to work through learning how to create external libraries for VFP. I am using Borland C++ 5.01 and am unable to link my libraries. Currently, I have been trying to do a simple "Hello, World" function, following the explanations in the Professional Features Guide. This is my code ; // include the library construction header file #include void hello(ParamBlk *parm) // the function definition { _PutStr("\nHello, World!\n"); //print the message }; // the FoxInfo structure registers the function FoxInfo myFoxInfo[]={ {"HELLO",(FPFI) hello, 0, ""}, }; //the FoxTable structure FoxTable _FoxTable={ (FoxTable *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo }; The source compiles okay, but when I try to link the file, I get this message... Error: Unresolved external '__PutStr' referenced from module mhello.c Is there something I'm doing wrong other than using Borland???
