[mpich-discuss] 64bit mpich2 compling with vs2008 on 64bit win7

[李朕]

I used 32bit mpich2 with vs2008 on 64 bit win7. It worked well. Now I want to use 64 bit mpich2. I compile the code with vs2008 as what I do with 32bit mpich2.  The errors like this: error LNK2001:error lnk2001 unresolved external symbol  __MPI_Allreduc.
Does anybody give me some help?
