SHARE_EASYLOGGINGPP is causing link errors #392

Hi, When I try using SHARE_EASYLOGGINGPP instead of the INITIALIZE_NULL_EASYLOGGINGPP + setStorage combination in the DLLSample, I obtain the following link error (compiling on VS2012):

error LNK2001: unresolved external symbol "class std::basic_string<char,struct std::char_traits,class std::allocator > el::base::utils::s_currentUser" error LNK2001: unresolved external symbol "class std::basic_string<char,struct std::char_traits,class std::allocator > el::base::utils::s_currentHost"

It seems related to the fact that SHARE_EASYLOGGINGPP does not call the macro ELPP_INITI_BASIC_DECLR, but I have not investigate any further.

Encountered the same issue, there was a possible fix posted here: https://github.com/easylogging/easyloggingpp/issues/386

I had this issue when using a library I wrote(which also used easylogging) which used a different version of easylogging than the executable using my library.

So, please ensure you're using the exact same easylogging header + source for both your dll and your exe.
