Hi,

I've recently installed Intel Parallel Studio XE 2015, here is the output:

icc --version
icc (ICC) 15.0.0 20140723
Copyright (C) 1985-2014 Intel Corporation.  All rights reserved.

how do I check what version of MKL?

How do I update to MKL 11.2 Update 1?

Here is the error output:

.../mkl/lib/intel64/libmkl_intel_thread.so: undefined reference to `__isoc99_sscanf'

 

Thanks

Tam

Since MKL is not a required part of ICC, you have to compile and link a small program to MKL and run it to get the version. See https://software.intel.com/en-us/node/471128 .

Regarding the undefined reference: please provide more details including, if possible, a small program that shows the linker error when a build is attempted.

Hi LCDM and Mecej4, 

Thanks for the reports.  Right, the issue was in MKL 11.2.0 and was fixed in MKL 11.2.1.  Please see 

https://software.intel.com/en-us/articles/intel-mkl-112-bug-fixes

DPD200547167 Fixed the problem of "ibmkl_core.so: undefined reference to `__isoc99_fscanf'" with MKL 11.2 on RHEL5

 You can check the MKL versions by check the MKL header file.  for example,  C:\Program Files (x86)\Intel\Composer XE 2013 SP1\mkl\include\mkl.h

#define __INTEL_MKL_BUILD_DATE 20140416

#define __INTEL_MKL__ 11
#define __INTEL_MKL_MINOR__ 1
#define __INTEL_MKL_UPDATE__ 3

or call function : 

 mkl_get_version
A C function that returns the Intel MKL version.
Syntax
void mkl_get_version( MKLVersion* pVersion);
Include Files
• C: mkl.h

or check the webpage: https://software.intel.com/en-us/articles/which-version-of-the-intel-ipp-intel-mkl-and-intel-tbb-libraries-are-included-in-the-intel

Best Regards,
