unresolved external symbol _GetLblAddress@0 ...

[sukratu]

Hi,
I am getting a linker error like
error LNK2019: unresolved external symbol _GetLblAddress@0 referenced in function _callasm@0..
where GetLblAddress is defined in separate asm file.
I am using VS 2013 project and compiling it as win32 project ("/TC")

.asm code
-----------------------------------------------------------
.586
.model flat, c

.code

PUBLIC GetLblAddress

GetLblAddress PROC
   
    //some assembly code
    //some assembly code

           ret

GetLblAddress ENDP

END

.C code
-----------------------------------------------------------
extern int GetLblAddress();
void callasm()
{
    int lbl = GetLblAddress();
    printf(...);
}

in compilation I am getting linker error.
I tried changing the name to _GetLblAddress but still getting same error.

Try extern int __stdcall GetLblAddress(void);

In C code define

Code Select Expand

extern int __cdecl GetLblAddress(void);
Because of your code

Code Select Expand

.model flat, c
...
GetLblAddress PROC
GetLblAddress ENDP

oops, that's right: model flat, C

Hi,

__cdecl worked! :t

Thanks TWell.
