I'm trying to test a C source code file that contains several separate functions, one function at a time. To do this, I need to stub out the other functions by linking in stub functions of the same name. I have not been able to determine how to do this as the linker returns a multiply defined symbol error. There should be a way to tell the Link Editor to ignore any previous definitions and use the last one. I do not want to touch the existing source file. I would appreciate any help in this matter. Thank you.

The .o file formats commonly found on Unix systems do not have sufficiently detailed information to permit loading only the relevant function(s) and data. Instead, the linker must read the entire .o file. If you want to replace any particular function, you must supply all symbols needed by the time ld gets around to noticing that .o file (which must be an archive entry; ld loads all files whose names end in .o whether needed then or not). -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7163) Domain: chris@mimsy.umd.edu Path: uunet!mimsy!chris
