[mpich-discuss] Undefined references to MPL, seems to be caused by --if-needed

[chan at mcs.anl.gov]

Hi Jed,

I can't reproduce the undefined MPL symbols error after configuring 1.3.1
with your options except --with-python=python2 under linux.  AFAIK, I don't
think mpich2 added "-Wl,--hash-style=gnu -Wl,--as-needed" in mpicxx.  Could
you check if you have LDFLAGS or CXXFLAGS somehow set in your environment ?
Or what platform are you building mpich2 on ?
