[mpich-discuss] Configuration issues for mpich2-1.5b2

[Bharath Ramesh]

I hit an error while trying to build mvapich2-1.9a2 which I can 
reproduce with mpich2-1.5b2. When I try configuring mpich2 or mvapich2 
hwloc isnt configured properly and configure ends up detecting the sizes 
incorrectly which results in a build failure when compiling. I reported 
this issue with mvapich2 mailing list[1].

The error I am noticing for mpich2-1.5b2 is as follows:

###
### Configuring hwloc core
###
checking hwloc building mode... embedded
configure: hwloc builddir: 
/home/bramesh/ARC/apps/build/mpich2-1.5b2/src/pm/hydra/tools/topo/hwloc/hwloc
configure: hwloc srcdir: 
/home/bramesh/ARC/apps/build/mpich2-1.5b2/src/pm/hydra/tools/topo/hwloc/hwloc
checking if want hwloc maintainer support... disabled (embedded mode)

checking size of unsigned long... (cached) 8
checking size of unsigned int... 0
checking for the C compiler vendor... gnu

configure line:
./configure --prefix=/home/bramesh/apps/mpich2 --enable-shared 
--with-pbs=/opt/torque/torque

The error I am noticing for mvapich2 is as follows:

###
### Configuring hwloc core

configure: hwloc builddir: 
/home/bramesh/ARC/apps/build/mvapich2-1.9a2/src/pm/hydra/tools/topo/hwloc/hwloc

./configure --prefix=$HOME/apps/mvapich2 --enable-shared 
--with-ib-include=/opt/ofed/ofed/include 
--with-ib-libpath=/opt/ofed/ofed/lib64 --with-pbs=/opt/torque/torque

If I built hwloc-1.5 or hwloc-1.6 separately in embedded mode I dont see 
the error. I was wondering what is the way to fix this issue so that I 
can build mvapich2 to use in our IB cluster. I am not subscribed to the 
list so would appreciate it if I am copied on the replies.
