Hi, I am trying to link a very old console program written in 1992 as I've
got to fix a bug (I haven't made any changes to it yet, just trying to build
the original source). I'm using Visual C++ 6.0 on Windows XP.

I'm getting the following unresolved externals:

Stop.

make1.exe - 9 error(s), 0 warning(s)


Any idea what libraries I need to add / change to resolve these? I've tried
internet searches but haven't found anything helpful.

I have compiled and linked this before succesfully, but that was 4 years ago
and an older PC, so something's changed in the mean time. I did try a build
in VS2010 but got *lots* of errors and warnings.

Thanks,

Michael

Michael,

From the presence of those "64" symbols it would appear that something
in your project has perhaps been built with a more recent version of
VS - I don't remember VC6 having the "64" variants of those library
functions.

You were right, I'd previously attempted a build using a newer version of
Visual Studio and was getting lots of errors + warnings about deprecated
functions. I then remember it was built with the old version so I switched
back. But it had left "new" object files behind and those were failing to
link under the old version, since I hadn't made any changes to the source the
object files hadn't got regenerated. Deleting everything and doing a
Rebuild all has fixed the problem and I'm now able to build the executable.


So now I can go ahead and try and fix the bug that started all this!

Thanks for your help.
