Error while loading shared libraries: libiomp5.so

[ederman]

Hello,

First, please let me say that I've searched the knowledge base for the similar questions before posting this, and I couldn't find a solution.
I installed IPP 7.0.7.319_ia32 under Ubuntu 10.04 LTS Lucid. And I am using Eclipse to compile my code. I've added the library paths:

/opt/intel/composer_xe_2011_sp1.10.319/compiler/lib/ia32
/opt/intel/composer_xe_2011_sp1.10.319/ipp/lib/ia32
/home/vavlab/Desktop/Ekber/Exa-tech/OpenCV-2.4.2/build/lib

to the "C/C++ Linker Libraries" path, and included the following libraries:

opencv_calib3d241d.lib

opencv_contrib241d.lib

opencv_core241d.lib

opencv_features2d241d.lib

opencv_flann241d.lib

opencv_gpu241d.lib

opencv_highgui241d.lib

opencv_imgproc241d.lib

opencv_legacy241d.lib

opencv_ml241d.lib

opencv_nonfree241d.lib

opencv_objdetect241d.lib

opencv_photo241d.lib

opencv_stitching241d.lib

opencv_ts241d.lib

opencv_video241d.lib

opencv_videostab241d.lib

ippac.lib

ippcc.lib

ippch.lib

ippcv.lib

ippdc.lib

ippdi.lib

ippi.lib

ippj.lib

ippm.lib

ippr.lib

ipps.lib

ippsc.lib

ippvc.lib

ippvm.lib

ippcore.lib

But while compiling, I get this error:

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

I use Eclipse SDK 3.7.2 Indigo, and each and everytime I restart my computer, I have to do "source /opt/intel/composer_xe_2011_sp1.10.319/ipp/bin/ippvars.sh ia32" to get a response for "echo $IPPROOT".

I am quite new to ipp, so please help me solve this. Many thanks in advance.

Regards.

you have to add the path to the libiomp5 libraries which is located into/opt/intel/composer_xe_2011_sp1.10.319/compiler/lib/ia32/

or just to source/opt/intel/composer_xe_2011_sp1.10.319/bin/compilervars.sh ia32

regards

[ederman]

Thanks for your answer.

I've already added that path, and mentioned in my thread. But it still doesn't work.
Any ideas?

[Ying_H_Intel]

Hi Ederman,

The libiomp5.so is from OpenMP threading library, from Intel Compiler. You should be right thathave the library 's path /opt/intel/composer_xe_2011_sp1.10.319/compiler/lib/ia32 specified in linked library path.

But i had some question about the library yourinclude:

opencv_videostab241d.lib

ippac.lib

ippcc.lib

ippch.lib

ippcv.lib

ippdc.lib

ippdi.lib

ippi.lib

ippj.lib

ippm.lib

ippr.lib

ipps.lib

ippsc.lib

ippvc.lib

ippvm.lib

ippcore.lib
why they are suffix are *.lib, under /opt/intel/composer_xe_2011_sp1.10.319/ipp/lib/ia32

should they be libippi.so or libippi.a?

Anyway, the error while loading shared libraries: libiomp5.so: cannot open shared object file: No such file or directory. looks be a run-time error, not compiling error.

So the solution still is to set right run -time environment: LD_LIBRARY_PATH. (not IPPROOT or set C/C++ Linker Libraries" path,which is for compiling phase).
Not sure how to doin Eclipse SDK.
Could you please try under command line to run your exe with command
> source /opt/intel/composer_xe_2011_sp1.10.319/ipp/bin/ippvars.sh ia32
> your exe

Or
>Export LD_LIBRARY_PATH=opt/intel/composer_xe_2011_sp1.10.319/compiler/lib/ia32:/opt/intel/composer_xe_2011_sp1.10.319/ipp/lib/ia32
:$LD_LIBRARY_PATH
>your exe.

Best Regards,
Ying

Hello Ying,

Thank you for your reply.

Actually, those libraries are ended with ".so" as you said, I wrote with ".lib" just wanted to indicate them as library names, anyway.

I tried your suggestion in the command line, but still get the same error. Seems like IPP is not working well under linux.
Any ideas?

[TimP]

Normal linux way is to use the LD_LIBRARY_PATH setting such as the compilervars script would give you. If you wish to have your own path for shared objects, you could place a symlink or actual copy of the .so there. Maybe that causes problems in choosing among updated versions.

[Ying_H_Intel]

Hi Ederman,

As we haven't your exe file, Could you please show some of command results to us
>ldd yourexe

>echo $LD_LIBRARY_PATH

Thanks
Ying

Hi Ying,

I did it as you said, and the output of command "ldd myexe" is:

And the output of "echo $LD_LIBRARY_PATH" is totally nothing, empty. Then I tried your previous answer as first do "export LD_LIBRARY_PATH=opt/intel/composer_xe_2011_sp1.10.319/compiler/lib/ia32:/opt/intel/composer_xe_2011_sp1.10.319/ipp/lib/ia32:$LD_LIBRARY_PATH", and then the output of "echo $LD_LIBRARY_PATH" is this:

Hi Ederman,

Could you please check ifthe libiomp5.so isin the path "opt/intel/composer_xe_2011_sp1.10.319/compiler/lib/ia32"?

or copy it to/opt/intel/composer_xe_2011_sp1.10.319/ipp/lib/ia32
then see if it can be found.
