Hi everybody,

I made an object file ("general.obj") including only a function ("Routine1(void)") and I would like to use this object file on an other project.

So I create an header file including the prototype of Routine1, and I call "Routine1" in "main.c".

 RLSTM8 LINKER/LOCATOR V2.44.12.199 - Lite (32 Kb code limited)  
 Copyright (c) Raisonance S.A.S. 1987-2012. All rights reserved.  
 ***ERROR 100 : UNRESOLVED EXTERNAL  
 SYMBOL : ?Routine1(MAIN)  
 LINK/LOCATE RUN COMPLETE, 1 ERROR  FOUND. 
  Error Code: 1

I don't understand why it declare an error.
Thank you for your help.

Hi,

Declaring the function prototype is not enough. You must also give the code to the linker.

Just include the obj file in the calling project, like if it was a source file.

Best Regards,

Vincent
