I wrote a assembly procedure to implement selection sort.
When I call this procedure from selectionSort.cpp file, I got an error
like this.
* ) Error 1 error LNK2019: unresolved external symbol _selectionSort referenced in function _main selectionSort.obj
**) Error 2 fatal error LNK1120: 1 unresolved externals selectionSort.exe
I USED LOCAL VARIABLES IN THE PROCEDURE. (for example : maxIndex)
IS A PROBLEM USING LOCAL VARIABLES
MASM HELP !!!!!!!!!!!!!!!1

look at:
PUBLIC [[langtype]] name [[, [[langtype]] name]]...
langtype must match function type in app file types ie the .cpp ,c ect.
langtype types are C, BASIC, FORTRAN, PASCAL, SYSCALL, or STDCALL
thus:
public _selectionSort
should be one of:
public C _selectionSort
public BASIC _selectionSort
public STDCALL _selectionSort
get it LOL

Right done do public _selectionSort -> _ <- is a problem
do: public [langtype] selectionSort
langtype can be one of:C, BASIC, FORTRAN, PASCAL, SYSCALL, or STDCALL
ie. public C selectionSort
or public STDCALL selectionSort
MASM will automaticly put the '_' in.
get it LOL

In addition to linking in the obj file, a few things to try (via process of elimination):
1. don't try to decorate your function using _. I think MASM might do that on its own.
2. remove the near keyword on your SelectionSort proc line
3. try adding % in front of public:
% public SelectionSort
