ifort: error #10031

[drimago]

Hi all,

First of all I have to say that I am a complete newbie when it comes to fortran on linux. I have used fortran before but not in a complex environment like a cluster and definitely not with lapack and all that.

So what I have now is a server running debian which i want to use to run some fortran code. the problem i am having is the following:

I want to compile a program called test.f90 so i write:

ifort test.f90 -o -lmkl_lapack -lmkl_blas

and i get the following error

ifort: error #10031: could not write to argument file '/tmp/ifortegHH3Earg'

and I have ho clue why or what to do about it.

Can anyone steer me in the right direction as to how to solve this issue?

Cheers,

Lucian

Ok it turns out that test.f90 had errors. But now I have other problems:

it seems that the way I was trying to use lapack and blas libraries is not the right way. the command

ifort test.f90 -o-lmkl_lapack -lmkl_blas

yelds: cannot find lmkl_blas. I did a search and there is a libmkl_lapack95 and same for blas. Modified the command but the same result: cannot find...

What am I doing wrong?

Cheers,

Lucian

The MKL libraries are in different directories than the compiler runtime and other libraries. By default, the compiler will not search for libraries in the MKL lib directory. Use the -mkl compiler option for simple jobs, and use the MKL Link Line Advisor for more intricate jobs.

Do not attempt to use the LAPACK-95 and BLAS-95 libraries unless your code calls the Fortran-95 interface routines.

Hi mecej4,

Thank you for your reply. After a lot of pushing and prodding I managed to figure out what the comand for ifort was supposed to be.

ifort -mkl test.f90 -o test

This created an executable file which ran my test program with no problem. This means that the mkl option tells the compiler to look for the libraries itself. I thought that I was supposed to tell the compiler which libraries to use like I was trying to do with the previous command. Eh well I am glad is working now.

AS for the lapack95 and blad95 this was a desperate attempt to make it working so no worries there. I will be making code that only calls for the mkl routines since this seems like the simple option.

Thank you very much for your help and excuse my newbie-ness!
