It sounds like you've done most everything right. You should also add
FLAGS='-xarch=v9', but that shouldn't kill you. On our Solaris 8
machines with LAM 7.0.3, I can do the following without problems:
% ./configure CFLAGS='-xarch=v9' CXXFLAGS='-xarch=v9'
FFLAGS='-xarch=v9' CC=cc \
CXX=CC FC=f77 --prefix=<DIR>
% make all install
% rehash
% mpicch -xarch=v9 foo.c -o foo
You may want to double check that you are using the mpicc that you
think you are - On more than one occasion, my problem has been that I
forgot to rehash (I'm a tcsh guy) and grabbed a random mpicc.
Hope this helps,
Brian
