Cannot load libmkl_def.so (Linux in C++ and Fortran)

[aurora]

Hi,

This message is being shown during the execution of my application.

I have a copy of libmkl_def.so in the same directory of the executable and the LD_LIBRARY_PATH variable pointing to the same folder. I've also tried to EXPORT LD_LIBRARY_PATH to the ...../mkl/lib/intel64 directory where all the mkl libs are.

There is only one version of mkl in the computer and only one Intel Compiler

The version of the icpc compiler is

$ ifort -v

ifort version 12.1.0

$ icpc -v

icpc version 12.1.0 (gcc version 4.1.2 compatibility)

Thanks in advance!

Check the file permissions on the shared library. If they are OK, you will need to provide more details on your OS, machine details, etc.

To add a directory to the search path for dynamic libraries, do this as root user:

1. add the line '/XYZ/mkl/lib/intel64' to the file '/etc/ld.so.conf'
   (replace XYZ with path to mkl lib)
2. run ldconfig

Permissions are OK, and the ld.conf solution didnt work :( Some additional info:

What is the output of the shell command

$ ls -l $LD_LIBRARY_PATH

?

[aurora]

$ echo $LD_LIBRARY_PATH
/opt/intel/composer_xe_2011_sp1.7.256/mkl/lib/intel64/:/home/aurora/Desktop/installs/full

The second one is the path of my executable

The first one contains:

What is the output of 'ldd FILE' (replace FILE with your application binary)?

[aurora]

Hi,

I think that disabling SELINUX all is working already... It is normal that SELINUX blocks dynamic libraries loaded at runtime?

Thanks!
