I used Visual C++ 2015. I received the following errors when I tried to build my g2o sample code.

Error   LNK2001 unresolved external symbol __imp_fflush 
Error   LNK2001 unresolved external symbol __imp_fflush
Error   LNK2001 unresolved external symbol sqrt 
Error   LNK2019 unresolved external symbol METIS_NodeComputeSeparator referenced in function cholmod_metis_bisector 
and so on.

About 172 errors are relative to LNK2001 and LNK2019. When I checked the file, it showed up most of the errors are relative to the Libs in SuiteSparse. I have already checked the library directories and additional library directories. But it still popped up these errors. I am new in the field of g2o. If someone can give me your kind hands, I'll very appreciate.

I add some Libs below: msvcmrtd.lib mscoree.lib It works, but it popped out the exception during the running time.
