How is a DLL linked to an application using the free command line compiler, BCC32 (version 5.5)? Both are written in ANSI C.

For example, if MyDLL.c is:

__declspec(dllexport) int __stdcall DLLFunction1(int num)
{ return(2*num); }

It is compiled to a DLL at the command line using: 

> bcc32 -WD MyDLL.c

to generate MyDLL.dll, MyDLL.obj. and MyDLL.tds. Then the lib file is generated using:

> implib MyDLL.lib MyDLL.dll

Both MyDLL.lib MyDLL.dll are added to the project directory. If the application, named test_MyDLL.c is:

__declspec(dllimport) void __stdcall DLLFunction1(int num);
int main(void){
	int ret_val=DLLFunction1(6);
	return 0; 
}

the compiler error is:

Error E2468 test_MyDLL.c 3: Value of type void is not allowed in function main
