[mpich-discuss] MPICH2 1.3: Problem with building several acrchitectrues from same source directory

[Reuti]

Hi,

why not build in two different directories? You don't have to untar  
the source tree twice, but create two directories on the same level  
where you untarred MPICH2 like "mpich2-32" and "mpich2-64" and after  
changing into each of them you execute "../mpich2-1.3/configure ... 
32flags..." resp. in the other directory for 64 bits.
