If it would be so easy, no one would have problems....

The easiness claim was made with two explicit conditions:

1. "These new options will work for the cases used by most users."

AND

2. The current Intel compilers are used.

I have found no example for which the /Qmkl (-mkl on Linux/OSX) option did not work. If you have such examples I am sure that they will be given adequate attention if you divulge them here.

As a matter of fact, I think I found an example (literally from the mkl/examples directory) where these options were unsuccessful.

I'm using (ifort -V):

Intel Fortran Intel 64 Compiler XE for applications running on Intel 64, Version 12.1.4.319 Build 20120410

which I think is the latest version.

Take a look at my post here:

http://software.intel.com/en-us/forums/showthread.php?t=105667&o=a&s=lr

This thread was about using MKL with simple C and Fortran-77 codes.

Using the Fortran 95 interfaces requires the MKL Lapack95 and Blas95 libraries to be specified at link time, and requires specifying the path for the module files when calling from Fortran-9X.

Earlier releases of MKL came with no prebuilt Lapack95 and Blas95 libraries.

Can anyone tell me how to use command line argument for compilation of c program.

at the very top of this thread Todd already gave two simpliest examples for windows and linux

Hi

I used the Link line advisor, to build a link line for my application, with PARDISO, it gave this line

 -L$(MKLROOT)/lib/intel64 -lmkl_scalapack_ilp64 -lmkl_cdft_core -lmkl_intel_ilp64 -lmkl_intel_thread -lmkl_core -lmkl_blacs_intelmpi_ilp64 -lpthread -lm

With this compiler option :

 -openmp -DMKL_ILP64 -I$(MKLROOT)/include

I created this makefile :

CFLAGS = -Wall -O3  -I ../../../SPOOLES-2.2_Intel -I /opt/intel/mkl/include -DMKL_ILP64 -DARCH="Linux" -DSPOOLES -DARPACK -DPARDISO -DMATRIXSTORAGE -DUSE_MT=1
FFLAGS = -O3 -nofor-main -openmp

CC=icc
FC=ifort

.c.o :
        $(CC) $(CFLAGS) -c $<
.f.o :
        $(FC) $(FFLAGS) -c $<

include Makefile.inc

SCCXMAIN = ccx_2.5.c

OCCXF = $(SCCXF:.f=.o)
OCCXC = $(SCCXC:.c=.o)
OCCXMAIN = $(SCCXMAIN:.c=.o)

ccx_2.5.a: $(OCCXF) $(OCCXC)
        ar vr $@ $?

when i type Make this gives me an error :

alex@iskandhar:~/Desktop/Buildfactory/Calculix/CalculiX/ccx_2.5_Intel_Pa/src$ make
make: *** No rule to make target `-L/opt/intel/mkl/lib/intel64', needed by `ccx_2.5'.  Stop.
alex@iskandhar:~/Desktop/Buildfactory/Calculix/CalculiX/ccx_2.5_Intel_Pa/src$

Where is my mistake..?

I understand nothing of makefiles, all i know is that i have to link with Intel compiled Spooles, Arpack, and Pardiso, all the sources have been compiled with icc and ifort

Can someone help me in this..?

BR

Alex

Hi,

In the makefile you need the only two `$(OCCXMAIN) ccx_2.5.a' dependencies for target ccx_2.5. So the line should be as follows:

ccx_2.5: $(OCCXMAN) ccx_2.5.a

Also please double check used MKL libraris. E.g. there is incorrect  -lmkl_blacs_intelmp$ in your post

How to reference these from a Fortran program?

I looked under PROJECT PREPERTIES, under FORTRAN,

and I jet FOUR possible choices. How would I know which one ?

Pr does it matter?

In some C/C++ project ( still in R&D state ) I decided to use runtime binding of MKL functions instead of dynamic linking. Here is a small example how I do it:
...
hMklRtDll = ::LoadLibrary( RTU("mkl_rt.dll") );
if( hMklRtDll == NULL )
break;

CrtPrintf( RTU("Dynamic library mkl_rt.dll loaded\n") );

pfMklGetVersionString = ( void ( * )( char *, int ) )::GetProcAddress( hMklRtDll, "MKL_Get_Version_String" );
if( pfMklGetVersionString == NULL )
break;
...
MKLVersion Ver = { 0x0 };
int iLenData = 256;
char szVerData[256] = { 0x0 };

pfMklGetVersionString( szVerData, iLenData );
CrtPrintfA( "\t%s\n", szVerData );
...
The most important things are that at a compilation phase I don't use any C++ compiler options related to MKL and at a linker phase I don't use any MKL libraries.
