DSS linking problem

[xpisani]

Im trying to compile and link a program that uses the direct sparse solver.
The compiler switches Im using are:

icc -O3 -fno-alias -tpp2 -mcpu=itanium2 -IPF_fma -openmp -D_USE_MKL_ -D_USE_SPARSE_ -LI/opt/intel/mkl/8.0.1/include /opt/intel/mkl/8.0.1/lib/64 -lmkl -lmkl_solver -lmkl_lapack -lguide -lpthread pruebadss.cpp

It compiles,but when linking these errors come:

/tmp/iccAnGUr6.o(.text+0x13d2): In function `main':
: undefined reference to `dss_create_'
/tmp/iccAnGUr6.o(.text+0x1822): In function `main':
: undefined reference to `dss_define_structure_'
/tmp/iccAnGUr6.o(.text+0x1852): In function `main':
: undefined reference to `dss_reorder_'

I've tried using the full path to the libraries (just in case), but it didn't work either.

Can anyone help me ?

Thank`s in advance.

Ximena.

Wouldn't you normally designate the include file path by -I ?
As you are using icc -openmp, -lguide and -lpthread should be taken care of, and it is preferable to do as you mentioned, simply give the full path names of the MKL libraries you want linked. That will avoid guesswork about whether libguide comes from MKL or icc. The newer of the two is generally preferable.
But here is your most likely problem:
Using linux, you must put the files in the order in which search is required. Your command searches the MKL libraries before the dependenencies from your .cpp are seen, and you search the dynamic libmkl before you have set any dependencies from your application or the other (static) mkl libraries. It should be OK to mix static and dynamic MKL libraries, if that's what you want, and you do it in order.

[xpisani]

Thank you Tim.

I tried ordering the libraries in almost every possible way, but icc still can't find the routines I listed. I also tried using all static libraries, except libmkl_solver, for wich I don't have a shared library (I'm using MKL 8.0.1, is this ok? could this be the problem?).
What else can I try? Any ideas?

Yes, you should try to link with mkl_solver.lib.I find them in mkl_solver.lib.
If you use C codes, these functions should be upper case.
For examples:
DSS_CREATE
DSS_DEFINE_STRUCTURE
DSS_FACTOR_COMPLEX
DSS_SOLVE_REAL
...................

dss_creat_ is wrong.

[p4top]

In mkl_solver.lib, they are maped into _DSS_CREATE, _DSS_DEFINE_STRUCTURE, _DSS_REORDER.

You should define them as C call.

extern "C" DSS_CREATE ....

Then compiler will generate _DSS_CREATE.

If you use fortran, please review the manual of fortran and define the name of funtion correctly.

[p4top]

Sorry, I don't notice that you are under linux, not win32. It maybe differ.
I only know that they exist in mkl_solver.

int void *




You can try the below C call definition for dss_create, dss_define_structure and dss_reorder functions, and link with mkl_sovler.

#undef DSS_CREATE
#undef DSS_DEFINE_STRUCTURE
#undef DSS_REORDER
extern "C" int DSS_CREATE(void *handle, int const *);
extern "C" int DSS_DEFINE_STRUCTURE(void *handle, int *opt, int *rowIndex, int *nRows, int *rCols, int *columns, int *nNonZeros);
extern "C" int DSS_REORDER(void *handle, int const *, int const *);
d
If compiler reports errors, you can delete #include "mkl_dss.h" firstly and try again with following codes.

typedef void * _MKL_DSS_HANDLE_t;
typedef char _CHARACTER_t;
typedef char _CHARACTER_STR_t;
typedef int _INTEGER_t;
#if !defined( _WIN64 )
typedef long _LONG_t;
#else
typedef long long _LONG_t;
#endif
typedef float _REAL_t;
typedef double _DOUBLE_PRECISION_t;
#define _DoubleComplexType struct { double r, i; }
typedef _DoubleComplexType _DOUBLE_COMPLEX_t;

@p4top:
Yes I'm under Linux, but I also tried under Windows. The funny thing is I'm not
having any kind of trouble linking in Windows. Even though I use dss_create() instead of what you said. The header takes care of that. Thanks for your help
anyway.

[p4top]

I know that gnu cc maybe map dss_create_ into _dss_create_.
Maybe libmkl_solver use _dss_create_ instead of dss_create_?
Why do you not open libmkl_solver and find it? Let's see what is the final symbol?

Hi there,

Unfortunately, I don't have an answer to this problem...however, as it's been a while since you posted this, I thought I'd ask if you found the solution yet, as I find myself in the exact same place as you!

Any help you could provide would be appreciated.
