Mark, This is a bit surprising. Before we go chasing this, can you try out the latest release of mpich (3.0.4) to make sure the problem still exists? -- Pavan On 03/28/2013 02:23 PM US Central Time, Mark E. Lee wrote:

To whom it may concern,

I have failed to compile MPICH-3.0.2 on 32 bit Arch Linux with both single and multiple make threads. My configure options are :

====BEGIN CONFIGURE OPTIONS====

./configure --prefix="/usr" \ --exec-prefix="/usr/lib" \ --bindir="/usr/bin" \ --sbindir="/usr/sbin" \ --sysconfdir="/etc/mpich" \ --includedir="/usr/include/mpich" \ --libdir="/usr/lib/mpich" \ --enable-shared \ --enable-fast=all,O3

====END CONFIGURE OPTIONS====

See below for the error:
