Re: Linking an existing DLL

Re: Linking an existing DLL

[Joan M. Moss]

Hi -

        On my PC (Windows NT 4.0, Service Pack 5) I have a DLL which
resides in
\WINNT\system32\   I do not have the source for the DLL so I can NOT
build the DLL on cygwin B20.1.  However, I would like to access it under
cygwin B20.1.  Is this possible?
        I followed the instructions for "Linking Against DLLs" from the
"User
Guide", i.e.:

echo EXPORTS > UISERVER.DEF
nm UISERVER.DLL \ grep ' T _' | sed 's/.* T _//' >> UISERVER.DEF

When I do this I it seems to work fine, however, a .def file is created
with only one line:  

bash-2.02$ cat UISERVER.DEF
EXPORTS
bash-2.02$

Any suggestions regarding how to proceed?  How do I locate Mumit Kahn's
site?  Could you give me the URL  for it?

with the cygwin-1.0CD (and very likely with the latest snapshots, too)
i succeeded with just linking in the DLL in question like that:

probe: probe.c 
    $(CC) $(CFLAGS) -o probe probe.c /cygdrive/d/WINNT/foreign.dll

however, if the functions in the DLL are _stdcall, but they are
exported without the decoration (without ..@nn), you've got to create
an import-library manually.

contact me, if the above gives errors like

  undefined reference to `SomeFunction@8'

Sad to say, but it like your DLL is striped for import library information.
(assuming the backslash is a typo in the mail, it should be a pipe | to
grep)

What kind of DLL is this?
