This is not case with your message, which is a case of MySQL library linkage with third libraries with unknown build process.

I am linking a Win32 project using MSVC++ 6.0 and get the following:

Linking... pthreadVC.lib(pthreadVC.dll) : error LNK2005: _pthread_create already defined in mysqlclient.lib(my_winthread.obj) Debug/wordnet.exe : fatal error LNK1169: one or more multiply defined symbols found Error executing link.exe.

This happens in mysql 4.0.12/3.23.56 with prebuilt libs from both debug and opt.

The problem appears to be that my_winthread.obj exports _pthread_create. However, the Red Hat pthreads library, pthreadVC.lib, also exports this symbol. Hence, the libraries are incompatible?
