Hi Katie and others,

I am responding to nersc and trilinos-users, since I raised 
this question with both.

My problem appears to be related to using the link flags that
I get from trilinos.  Our build system greps those out of
the trilinos file, Makefile.export.aztecoo.macros.  That
leads to a link line fragment,

-lessl  /usr/common/usg/LAPACK/3.0/liblapack.a -llapi_r -L/usr/lpp/ppe.poe/lib/threads -L/usr/lpp/ppe.poe/lib -L/usr/lpp/ppe.poe/lib/ip -L/lib/threads -lmpi_r -lvtd_r -lxlf90 -L/usr/lpp/xlf/lib -lxlopt -lxlf -lxlomp_ser -lpthreads -lm_r -lm -lc_r /usr/lpp/ppe.poe/lib/libc.a

from

b0301.cary$ AZTECOO_FLIBS=`grep AZTECOO_FLIBS $TRILINOS_INCDIR/Makefile.export.aztecoo.macros | sed 's/^.* = //'`
b0301.cary$ echo $AZTECOO_FLIBS
/usr/common/usg/LAPACK/3.0/liblapack.a -llapi_r -L/usr/lpp/ppe.poe/lib/threads -L/usr/lpp/ppe.poe/lib -L/usr/lpp/ppe.poe/lib/ip -L/lib/threads -lmpi_r -lvtd_r -lxlf90 -L/usr/lpp/xlf/lib -lxlopt -lxlf -lxlomp_ser -lpthreads -lm_r -lm -lc_r /usr/lpp/ppe.poe/lib/libc.a

When I remove the -L items from this and the last absolute library, it links.

So it looks I will need to do more postprocessing on the AZTECOO_FLIBS
variable before I can use it.

Thanks.....John
