Helo,
I'm running ubuntu 10.04 and I use intel fortran 11.1.069 with the latest MKL version. I want to use superLU library but I don't know how to link it with BLAS and how to call the routines in my programs. I have also installed superLU 3 which was in the ubuntu repositories but I don't think it is linked with intel fortran. I attach the readme and the make.inc file in order to make clearer what I ask.
Thanks in advance!!

SuperLU (Version 4.0)

SuperLU contains a set of subroutines to solve a sparse linear system
A*X=B. It uses Gaussian elimination with partial pivoting (GEPP).
The columns of A may be preordered before factorization; the
preordering for sparsity is completely separate from the factorization.
SuperLU is implemented in ANSI C, and must be compiled with standard
ANSI C compilers. It provides functionality for both real and complex
matrices, in both single and double precision. The file names for the
single-precision real version start with letter "s" (such as sgstrf.c);
the file names for the double-precision real version start with letter "d"
(such as dgstrf.c); the file names for the single-precision complex
version start with letter "c" (such as cgstrf.c); the file names
for the double-precision complex version start with letter "z"
(such as zgstrf.c).
SuperLU contains the following directory structure:
SuperLU/README instructions on installation
SuperLU/CBLAS/ needed BLAS routines in C, not necessarily fast
SuperLU/DOC/ Users' Guide and documentation of source code
SuperLU/EXAMPLE/ example programs
SuperLU/FORTRAN/ Fortran interface
SuperLU/INSTALL/ test machine dependent parameters; the Users' Guide.
SuperLU/MAKE_INC/ sample machine-specific make.inc files
SuperLU/MATLAB/ Matlab mex-file interface
SuperLU/SRC/ C source code, to be compiled into the superlu.a library
SuperLU/TESTING/ driver routines to test correctness
SuperLU/Makefile top level Makefile that does installation and testing
SuperLU/make.inc compiler, compile flags, library definitions and C
preprocessor definitions, included in all Makefiles.
(You may need to edit it to be suitable for your system
before compiling the whole package.)
Before installing the package, please examine the three things dependent
on your system setup:
1. Edit the make.inc include file.
This make include file is referenced inside each of the Makefiles
in the various subdirectories. As a result, there is no need to
edit the Makefiles in the subdirectories. All information that is
machine specific has been defined in this include file.
Example machine-specific make.inc include files are provided
in the MAKE_INC/ directory for several systems, such as
IBM RS/6000, DEC Alpha, SunOS 4.x, SunOS 5.x (Solaris), HP-PA and
SGI Iris 4.x. When you have selected the machine to which you wish
to install SuperLU, copy the appropriate sample include file (if one
is present) into make.inc. For example, if you wish to run
SuperLU on an IBM RS/6000, you can do
cp MAKE_INC/make.rs6k make.inc
For the systems other than listed above, slight modifications to the
make.inc file will need to be made.
2. The BLAS library.
If there is BLAS library available on your machine, you may define
the following in the file SuperLU/make.inc:
BLASDEF = -DUSE_VENDOR_BLAS
BLASLIB =
The CBLAS/ subdirectory contains the part of the C BLAS needed by
SuperLU package. However, these codes are intended for use only if there
is no faster implementation of the BLAS already available on your machine.
In this case, you should do the following:
1) In SuperLU/make.inc, undefine (comment out) BLASDEF, and define:
BLASLIB = ../lib/blas$(PLAT).a
2) Go to the SuperLU/ directory, type:
make blaslib
to make the BLAS library from the routines in the CBLAS/ subdirectory.
3. C preprocessor definition CDEFS.
In the header file SRC/slu_Cnames.h, we use macros to determine how
C routines should be named so that they are callable by Fortran.
(Some vendor-supplied BLAS libraries do not have C interface. So the
re-naming is needed in order for the SuperLU BLAS calls (in C) to
interface with the Fortran-style BLAS.)
The possible options for CDEFS are:
o -DAdd_: Fortran expects a C routine to have an underscore
postfixed to the name;
o -DNoChange: Fortran expects a C routine name to be identical to
that compiled by C;
o -DUpCase: Fortran expects a C routine name to be all uppercase.
4. The Matlab MEX-file interface.
The MATLAB/ subdirectory includes Matlab C MEX-files, so that
our factor and solve routines can be called as alternatives to those
built into Matlab. In the file SuperLU/make.inc, define MATLAB to be the
directory in which Matlab is installed on your system, for example:
MATLAB = /usr/local/matlab
At the SuperLU/ directory, type "make matlabmex" to build the MEX-file
interface. After you have built the interface, you may go to the MATLAB/
directory to test the correctness by typing (in Matlab):
trysuperlu
trylusolve
A Makefile is provided in each subdirectory. The installation can be done
completely automatically by simply typing "make" at the top level.
The test results are in the files below:
INSTALL/install.out
TESTING/stest.out
TESTING/dtest.out
TESTING/ctest.out
TESTING/ztest.out

The references to the G77 I/O routines (do_fio, etc.) and the double underscore after "c_fortran_dgssv" in hbcode1.o and f77main.o indicate that you have some left-over object files that were compiled with a different compiler than Intel Fortran. Please delete the object files, and do "make" again.
