Unresolved external symbols in compiling 32 bit application in Windows 64

Question

So I am trying to compile legacy app from 32 bit to 64 bit.. I re-compiled all of the libs it used and made it look into WIN SDK6.0A x64 bit for libs..

I am using:

• Visual Studio Professional Edition 2008
• Visual C++
• dotNet Framework 3.5 SP1
• Windows Server 2008R2
• Windows SDK is 6.0A

Everythings finally coming up but I am getting these weird undefined symbol errors:

error LNK2019: unresolved external symbol InterlockedDecrement referenced in function ...
error LNK2019: unresolved external symbol InterlockedIncrement referenced in function ...
error LNK2019: unresolved external symbol GetModuleBaseName referenced in ...
error LNK2019: unresolved external symbol EnumProcessModules referenced in ...
error LNK2019: unresolved external symbol EnumProcesses referenced in ...
error LNK2019: unresolved external symbol GetProcessMemoryInfo referenced 

The problem is these are all win stuff from SDK. InterlockedDec and InterlockedInc are coming from kernel32.lib GetModuleBaseName, EnumProcessModules, EnumProcesses,GetProcessMemoryInfo are in psapi.h but also kernel32.lib or psapi.lib

I checked C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib\x64 and both libs kernel32.lib and psapi.lib are there.

It definitely looks up the libs at right spot. I turned on /VERBOSE:LIB and it points to the correct folder.

So I am really confused why isnt it finding them.

Any ideas???

Thanks

So I finally figured it out, kinda... It wasnt finding psapi.lib

In Project->Linker->Additional dependencies instead of just saying psapi.lib I gave full path to it and it worked... not really sure why it failed to find it before but oh well...
