Thanks for fast reply.
I had already read the chapter 5, but building the solution "Berkeley_DB.sln" (just db sub-solution) in the "build_windows" directory with VC++ 2008 Express, I got the error "mut_win32.obj : error LNK2019: unresolved external symbol ___emit__ referenced in function _func_mutex_pause".
I'm not familiar with VC++ because I'm Embarcadero C++ Builder user.
Therefore I used the dll in the "Berkeley DB 6.0.30.msi" installer,
What the above error is?
