[petsc-dev] SuperLU link error on BGP FEN

[John R. Cary]

I am trying to link facets on a FEN of surveyor.alcf.anl.gov.  It ends
with the error,

/gpfs/home/projects/facets/surveyor/contrib-xlc-9.0/petsc-3.1-p4-ser/lib/libsuperlu_4.0.a(dldperm.o): 
In function `dldperm':
/gpfs/home/cary/facetspkgs/builds/petsc-3.1-p4/ser/externalpackages/SuperLU_4.0/SRC/dldperm.c:127: 
undefined reference to `mc64id_'
/gpfs/home/cary/facetspkgs/builds/petsc-3.1-p4/ser/externalpackages/SuperLU_4.0/SRC/dldperm.c:134: 
undefined reference to `mc64ad_'

which indicates that the SuperLU compiled with PETSc did
not get the fortran underscoring flag correct (which should
be no underscore with xlf).  nm shows

login1.surveyor$ nm 
/gpfs/home/projects/facets/surveyor/contrib-xlc-9.0/petsc-3.1-p4-ser/lib/libsuperlu_4.0.a

that the underscored symbol is being called, but the
underscore-free symbol is what was defined.

My PETSc configure line was

#!/bin/sh
/gpfs/home/cary/facetspkgs/builds-surveyor-xlc/facetspkgs/petsc-3.1-p4/ser/configure 
\
   
--prefix=/gpfs/home/projects/facets/surveyor/contrib-xlc-9.0/petsc-3.1-p4-ser 
\
   --with-mpi=0 \
   --with-debugging=0 \
   --with-x=0 \
   --with-cc='xlc_r' \
   --with-cxx='xlC_r' \
   --with-fc='xlf_r' \
   --COPTFLAGS='-O2 -g' \
   --download-superlu \
   
--with-lapack-lib=/home/projects/facets/intrepid/contrib/lapack-ser/lib/liblapack.a 
\
   
--with-blas-lib=/home/projects/facets/intrepid/contrib/lapack-ser/lib/libblas.a 
\
   
PETSC_DIR=/gpfs/home/cary/facetspkgs/builds-surveyor-xlc/facetspkgs/petsc-3.1-p4/ser 
\
   PETSC_ARCH=facets-ser \
   --CFLAGS='-q64 -qlanglvl=redefmac' \
   --CXXFLAGS='-q64 -qlanglvl=redefmac' \
   --FFLAGS='-q64 -qextname=flush' \
   --with-shared=1

so I think that PETSc had enough info to figure out the underscoring.
Perhaps this is a bug.

But regardless, is there a workaround?

Thx....John
