Using Lapack with ifort on linux

notmuchnoise — Wed, 03 Feb 2010 20:40:38 GMT

Hello,

I was wondering if someone could help me please?

Im trying to access some of the routines in the lapack

In my f90 code i have

program a
use mkl95_lapack
implicit none

etc

call steve(variables here)

Normally I would compile a program with "ifort program.f90"

i use this to set ifort up prior to compiling "source /opt/intel/Compiler/11.1/064/bin/ifortvars.sh intel64"

The ifort files are located along the file tree "/opt/intel/Compiler/11.1/064"

with the mkl directory at "/opt/intel/Compiler/11.1/064/mkl"

I'm unsure as to what commands I would use now that I require the use of lapack?

at the moment i get the following error:

a.f90(2): error #7002: Error in opening the compiled module file. Check INCLUDE paths. [MKL95_LAPACK]
use mkl95_lapack
----^
compilation aborted for a.f90 (code 1)

Thanks for any help

(sorry about the very beginner question)

Compiler makes it clear, can't find module you specified. check your LD path first, to make sure compiler knows where to find it (/include folder). On the other hand, you say that you set the environmen already. What about location for *.mod files?

Hello,

The mkl95_lapack.mod is in /opt/intel/Compiler/11.x/0xx/mkl/include/[32|em64t]

Assume 32bit,the command may like

ifort -I//opt/intel/Compiler/11.x/0xx/mkl/include/32 main.f

-L/opt/intel/Compiler/11.1/059/mkl/lib/32 -lmkl_intel_c -lmkl_intel_thread -lmkl_core -liomp5
