Error while loading shared libraries: libiomp5.so

ederman — Tue, 17 Jul 2012 07:44:24 GMT

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

Thanks for your answer.

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

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?

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.

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
