the winecfg confused me about DLL overriding. In the 'libraries'

know where to load the native file when need? does it mean i also

directory? if so, why i have to bother with the winecfg, why not
directlly copy files into the "c:\windows\system[32]' and hope it

and, i found there are still many DLLs in the "c:\windows\system[32]"

does this mean?
From Wine's point of view, there are two kinds of windows dll's:
1. One that is actually a Linux .so and implements the stuff you expect
to find in the dll. The wine devs write this stuff. How this happens is
black magic and you don't need to worry about it. What you do need to
know is that wine calls these things "builtin"
2. Actually real Windows .dll files that you pinched off a windows
install somewhere, or were installed by a third party package/app. You
can make these things happen by copying a .dll from somewhere else to
the appropriate directory in ~/.wine/drive_c/<somewhere>. Wine calls
these things "native". They look like windows binaries becuase they are
windows binaries in every respect. Forget for now that they are living
on a disk being run by a Linux install - wine knows what to do with
them.
Enter winecfg. Some .dlls work better as builtin than as native, and
some work better as native. For example, there's a builtin called
gdi.<something_or_other> that will never in a brazillion years work as
What you mean whyt
"never in a brazillion years"

a native. These things are tagged as builtin in winecfg. For the rest,
the normal way of doing things is to say that everything is a builtin,
and adjust if and when you realize that the builtin doesn't have some
essential functionality. The wine devs want you to use builtins as much
as possible, then you can tell them what is broken so they can fix it.
This is the default in winecfg.
Wine will never use a native .dll unless you say it must in winecfg. To
do this you must:
1. Copy the native .dll (which you often steal from a Windows install)
into .wine/windows/system32,or let the program's installer do it for
you.
2. Tag it as a native in winecfg. You can do this on a glocal or per-app
basis, do you know how to do this?
The main trick is that wine will only use natives if you told it to do
so in winecfg, and then the .dll must exist on disk in the palce
windows expects it to be.
