LNK2001: unresolved external symbol

I recently joined a C++ project and I had to make the build process with no hard-coded paths to dependencies and I decided to use the References. Everything is good and nice until one of the projects gives the error from the title: linker error - some external symbol could not be found. If you want to get more information on linker, you can use /verbose option.
In my case, at the setting Project Properties->Linker->General->Link Library Dependencies was set to No. Setting it on Yes, fixed all the linker errors.

Hopes it helps!

On VC++ 2005 Express intellisense

When working with a large codebase in VC++ 2005 Express SP1, the IDE might crash when updating intellisense.
It looks like there are a couple of hotfixes for this problem: KB913377 and KB947315.
After installing, the IDE did not crush anymore (tested on Webkit).
