Hi,
I'm trying to recompile a program originally done with VC6, with VC++
Express plus the Platform SDK. I'm an embedded C programmer... I
know next to next to nothing about programming Windows applications.
So, I got some unresolved external link errors about security_cookie,
which I found I could resolve by adding "bufferoverflowU.lib" to
Project | [projectname] Properties | Configuration Properties | Linker
| Command Line
I am also getting some unresolved external errors about various RTC
things, like:
....
error LNK2019: unresolved external symbol @_RTC_CheckStackVars@8
....
error LNK2019: unresolved external symbol __RTC_CheckEsp
....
error LNK2001: unresolved external symbol __RTC_Shutdown
....
error LNK2001: unresolved external symbol __RTC_InitBase
....
error LNK2019: unresolved external symbol __RTC_UninitUse
....
I looked in the directory where bufferoverflowU.lib exists for
something with rtc in the name, but came up empty. I searched and
found some good descriptions of the RTC flags, and now I know
what they're for, but I don't know how to fix this. How do I resolve
these errors?
Thanks,
JeanneP

It looks like you're linking againt a different verison of the runtime
libraries than what you're compiling against.
Check your library paths and make sure that the VC6 libary directory is NOT
on the library path before the VC8 library path. You might try a simple
experiment of renaming the root directory of the VC6 installation to see
what effect that has. Of course, if VC6 is no longer installed on the
machine....

Yes, VC6 (or, rather, VC98, part of VS6) is still installed on my
machine, and you correctly identified the problem. Thanks!
