Question

How to resolve LNK 1169 and 20

Answer 1

It is basically impossible to solve linker errors withut seeing the code.

Here is some info from Microsoft on their results for those:
```
Linker Tools Error LNK1169
one or more multiply defined symbols found

The build failed due to multiple definitions of one or more symbols.
This error is preceded by error LNK2005.

The /FORCE or /FORCE:MULTIPLE option overrides this error.
```
and
```
Linker Tools Error LNK1120
number unresolved externals

Error LNK1120 gives you a count (number) of unresolved externals for
this link. The conditions that cause unresolved externals are described
with error LNK2001, which precedes this error message (once for each
unresolved external).
```

Are you using globals? Globals in a header file?
