Found recently with the compilation of strange problems especially attached, last week was not done! But now found himself but fell in love with him, at least now met better than ever! The problem today is fatal error LNK1169: find one or more multi-definition symbols. At first I thought it was similar to what I had encountered before, so I changed it to a precompiled form, but it didn't work, but it was a little bit. Found a lot of people's posts. One of them is a solution to the 2005, but I still try it out and find that I can, but I don't understand. On the post: Add/force/force to the Add-on option in the command-line, such as the item, properties , and so on. But it 's not that good. Later, it was said that the reason for the head file, In fact, it is not very clear. But you can't torture yourself, just think: If you define a variable in a header file, either the class member variable is either defined as a local extern or static variable, and the result is all pass!
