i just tried building dolphin for the first time using the newly updated guide on the google code page. at the end of everything, the build failed and this error message was displayed:
LINK : fatal error LNK1181: cannot open input file 'iphlpapi.lib'
could someone please help?

It is included in the Windows SDK...perhaps people just need to add some more paths...I'll check into it in a few.
OK...I just setup a VM with Windows 7 and followed my own instructions (using VS Express)...dolphin built and linked fine (32bit, testing 64bit now...).
just tried building dolphin again, i get the error at the beginning now

Edit: tried building with latest revision, still same results:
13>LINK : fatal error LNK1181: cannot open input file 'iphlpapi.lib'
========== Build: 12 succeeded, 1 failed, 10 up-to-date, 0 skipped ==========
Ah yeah...the 7.0A files (the part of the Windows SDK which comes with Visual Studio) doesn't have x64 stuff...only 32bit. Quite annoying :|
so how would i fix this problem? reinstall it?
The only way that could get rid of that error for me was installing the Windows sdk like Xtreme said and changing the toolset for all Dolphin projects to Windows7.1SDK, but that will change vcproj files in the source, there should be another way to solve this...
Maybe the another way is getting a pro VS version :/

The annoying this about this is that I tried this in my test Visual Studio Express VM, and it didn't work for me. Instead, I got an error like
Code:
C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\Win32\Microsoft.Cpp.x64.Targets(58,5): error : Required file "" is missing.
