error while loading shared libraries: libiomp5.so

[pierre96321478]

Dear all,

I want to run a subroutine written in FORTRAN within an engineering software package. The compilation went well but apparently a shared library is missing as I have this error message:

error while loading shared libraries: libiomp5.so: cannot open shared object file: No such file or directory

I am using a Linux OS.

Any help would be appreciated.

If you are running on the platform where the compiler and libraries are installed, the usual compile environment variable setting script, e.g.
source /opt/intel/bin/compilervars.sh intel64
will add the library path to LD_LIBRARY_PATH.
If running where the shared library isn't present, you may install the redistributable library package, or take other remedies such as copying the library over and adding it yourself to LD_LIBRARY_PATH, or linking libiomp5.a (in your final link, preferably not when making a .so).

[pierre96321478]

Thanks a lot for your answer. Actually, I can locate the shared library libiomp5.so under the Intel directory but the compiler cannot find it on its own. Do you know how to add the library to LD_LIBRARY_PATH?

[TimP]

I suppose you mean that you are running without sourceing compilervars, and the run-time loader doesn't have the LIBRARY_PATH; you must repeat the LIBRARY_PATH setting in the compilervars script e.g.
export LD_LIBRARY_PATH=/opt/intel/composer_xe_2011_sp1.7.256/compiler/lib/intel64:$LD_LIBRARY_PATH
(use the path where you found it)

One way is to issue the following command to the shell:

$ export LD_LIBRARY_PATH=directory containing shared library>:$LD_LIBRARY_PATH

Note the colon separating the components of LD_LIBRARY_PATH

[pierre96321478]

I issued exactly this command in the terminal:

$export LD_LIBRARY_PATH=home/tph201/intel/Compiler/11.0/081/lib/intel64:$LD_LIBRARY_PATH

and the Bash replied:

LD_LIBRARY_PATH=home/tph201/intel/Compiler/11.0/081/lib/intel64:: No such file or directory

I have double-checked that the path is correct. Should I try to re-install Intel compiler?

[TimP]

The correct entry should have been visible in LD_LIBRARY_PATH after you sourced the ifortvars script to set up for compiling. If the libraries aren't actually present there, then uninstall and re-install would be advisable. But you said you were able to find the library, so it should be found if your LD_LIBRARY_PATH has a match.

[mecej4]

>$export LD_LIBRARY_PATH=home/tph201/intel/Compiler/11.0/081/lib/intel64:$LD_LIBRARY_PATH

There should be a slash character ('/') preceding home.

[pierre96321478]

Thanks a lot Tim and Mecej for your patience. I managed to export the LD_LIBRARY_PATH as followed this steps:

me:~$ /home/tph201/intel/Compiler/11.0/081/lib/intel64

bash: /home/tph201/intel/Compiler/11.0/081/lib/intel64: is a directory

me:~$ export LD_LIBRARY_PATH=/home/tph201/intel/Compiler/11.0/081/lib/intel64

me:~$ echo $LD_LIBRARY_PATH

bash: /home/tph201/intel/Compiler/11.0/081/lib/intel64

But the shared library is still missing when I run the code afterwards. I will try to reinstall ifort.

Cheers,

Pierre

The same thing happened to me and I tried reinstallation but it still doesn't work

Hello,

assuming you have installed the latest Intel Composer XE 2011 Update 8. Could you please verify that libiomp5.so is present in
/composer_xe_2011_sp1.8.273/compiler/lib/[intel64|ia32]

Also, after sourcing the environment like this (as described in an earlier post)
source /composer_xe_2011_sp1.8.273/bin/compilervars.sh [intel64|ia32]

$LD_LIBRARY_PATH should point to the same directory containing libiomp5.so.

This has to be set every time you're executing your application (or you install the library to a system wide library directory).

Best regards,

Georg Zitzlsberger

same kind of error while running the matrix multiplication for mic ...sample code from vtune amplifier. 

and my bashrc 

export PATH=/opt/intel/composer_xe_2013.0.079/bin/intel64_mic/:$PATH
export INCLUDE=/opt/intel/composer_xe_2013.0.079/compiler/include/mic/:$INCLUDE
export LD_LIBRARY_PATH=/opt/intel/composer_xe_2013.0.079/compiler/lib/mic/:$LD_LIBRARY_PATH

export PATH=/opt/intel/impi/4.1.0.018/mic/bin/:$PATH
export INCLUDE=/opt/intel/impi/4.1.0.018/mic/include/:$INCLUDE
export LD_LIBRARY_PATH=/opt/intel/impi/4.1.0.018/mic/lib/:$LD_LIBRARY_PATH

./matrix.mic: error while loading shared libraries: libiomp5.so: cannot open shared object file: No such file or directory

[kiran_s_]

just copy that  libiomp5.so file to mic card 

scp  libiomp5.so username@mic0:/tmp

and then run that executable.

Thank you
