Lior Ella said...Hi Antonio and Xingguang,
I ran into the same problem as Antonio, and after messing around with it for about an hour I figured it out. The problem was that I tried to create the *.lib files in the visual studio directory itself. Because admin privileges are required to add files to that directory, it failed.
The solution is to run lib.exe through the visual studio command prompt, but to do it in a "neutral" directory, where the *.def files are found. This will work.
Thanks a lot!

Solution:
As Lior Ella said, the reason for this error is 'Win7 admin privilege'. However, neither Libaray Manager nor Win7 gives the CORRECT debug info. It is easy to be confused here.
To solve this problem is easy, just COPY the files in /Program Files/MicrosoftVisual Studio 9.0/VC/bin to a ¡¯Neutual¡¯ path, i.e. D:/. Then execute the lib commandagainand theLNK1104 error is gone :)
Anyway, this issue is DISGUSTING:(
