在Windows上编译我自己的PHP扩展，但得到了LNK 2005错误

I am using VC 2008 express, and tried to compile my own PHP extension with that. Any idea about the following error?

    Where did you get this libcpmtd.lib from?

    • Was it compiled with the same /Mx settings as your .dll project?
    • Did you use function level linking in one or both projects?
