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

[Jayesh Krishna]

Hi,
 You need to uninstall your 32-bit version and install the 64-bit version of MPICH2 (http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads).

Regards,
Jayesh

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



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?
