everybody! I want to work with some mpi.h library in visual studio c++ 2010, but when i call function of the library, for example MPI_Init(), it gives me "error LNK2019 unresolved external symbol". In addition, compiler do not give the error on #include . How to fix this error?

Have you linked your .lib file using #pragma comment or project settings (linker->input) ? – CreativeMind Jan 22 '15 at 12:21

@Pavel You are doing `#include
`? – Jonathan Mee Jan 22 '15 at 12:21 -
I add msmpi.lib to the linker->include->additional dependencies – Pavel Jan 22 '15 at 12:24

@Pavel linker->include? – Luchian Grigore Jan 22 '15 at 12:25

Error is the same, as it was, i.e. "error LNK2019 unresolved external symbol" – Pavel Jan 22 '15 at 13:05

This link is helpful, however the post would be more valuable if you could paste the pertinent text in your answer as well. – Jonathan Mee Jan 22 '15 at 12:34

Thank you for the link, it is very useful, but nothing helps. May be it is compatibility problem, or something else - I don't know. I am gonna reinstall visual studio, hpc and all this staff again, may be it would help. – Pavel Jan 22 '15 at 14:49
