c++ - ResolveIt produces linker error

Hello,

the following code sample, included in a larger project, produces the
following linker result:

Has someone (Jan or Walter :-)) ) an idea, what's going wrong here. I don't
have the right conclusion.

Thanks a lot

I am not sure, but I think this one resides in UUID.LIB. So, include UUID.LIB into your project.

This is weird.

And so is this. Are you sure you didn't overwrite these files? Don't worry, be Kneppie! Jan

I tried it, and it compiles and links without error. I suggest that perhaps
your library files have been corrupted or the wrong ones are being linked
in. -Walter

P.S. I compiled with the following command:

sc
test.cpp -cpp -Aa -r -J -mn -C -WA -ff -5 -a1 -c -g -gg -DHLDRIVER -D_DEBUG=
1
