Subject: [OMPI devel] 1.7.4rc2r30168 - warnings for pointer/integer of different size
From: Paul Hargrove (phhargrove_at_[hidden])
Date: 2014-01-09 04:07:22


The following three warnings occur on 32-bit targets, and can each be
avoided by adding an intermediate cast to uintptr_t or intptr_t:

-bash-4.2$ grep -B2 'different size' make.log

The following additional warnings show up on a 32-bit Solaris system with
InfiniBand.
I've not looked at whether or not an (u)intptr_t cast is appropriate for
these.
