I'm seeing some commonblock warnings. I see similar stuff in some nightlybuilds [in the past few days]. http://ftp.mcs.anl.gov/pub/petsc/nightlylogs/archive/2014/10/06/filtered-mak...

Looking at the build - I see some funny stuff "--enable-shared --disable-shared"

This must be related to using gnupackage - and then adding extra options. Removing '--disable-shared' appears to get rid of the warnings. So easy thing to do [to fix this issue] is strip out shared library options from MPICH.py. [and prefer the ones from package.py]. However do we still want to support the following? help.addArgument('MPI', '-download-mpich-shared=<bool>', nargs.ArgBool(None, 1, 'Install MPICH with shared libraries')) Satish On Wed, 8 Oct 2014, Barry Smith wrote:

Satish,

Can you please upgrade to this. You can also remove the def MPICHInstall(self): and just call the parent GNUPackageInstall.

Thanks
