Linux - No shared libraries were found in the Waterfall procedure

Hi!
I'm a Linux user. In my bashrc there is:

"export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/intel/ipp/sharedlib"

that has the same semantics than your command, but I always get this error at RUNTIME (not compile-time):

"Error at loading of ippCV library: No shared libraries were found in the Waterfall procedure"

further info:

[bash]ls /opt/intel/ipp/sharedlib/
libiomp5.so libippcc.so.7.0 libippcore.so.7.0 libippcv.so.7.0 libippi.so.7.0 libipps.so.7.0
libippcc.so libippcore.so libippcv.so libippi.so libipps.so[/bash]
I also noticed that the directory structure seems to be different from the usual (i.e. the structure that comes with previous versions of ipp). I thinked that it's related to newer version 7.0. It's this true or I did something wrong installing ipp? I used all default options!

Other useful informations:

1. typing "ldd myprogram" (zdfMod is my program) returns this:
[bash]ldd zdfMod 
linux-gate.so.1 => (0xb77cd000)
libippi.so.7.0 => /opt/intel/ipp/sharedlib/libippi.so.7.0 (0xb775c000)
libipps.so.7.0 => /opt/intel/ipp/sharedlib/libipps.so.7.0 (0xb771c000)
libippcc.so.7.0 => /opt/intel/ipp/sharedlib/libippcc.so.7.0 (0xb7708000)
libippcore.so.7.0 => /opt/intel/ipp/sharedlib/libippcore.so.7.0 (0xb76f1000)
libippcv.so.7.0 => /opt/intel/ipp/sharedlib/libippcv.so.7.0 (0xb76d8000)
libgsl.so.0 => /usr/lib/libgsl.so.0 (0xb74e1000)
libgslcblas.so.0 => /usr/lib/libgslcblas.so.0 (0xb74ae000)
libACE-5.6.3.so => /usr/lib/libACE-5.6.3.so (0xb7343000)
librt.so.1 => /lib/tls/i686/cmov/librt.so.1 (0xb733a000)
libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7336000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7240000)
libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb721a000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb71fa000)
libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb70a0000)
libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0xb7087000)
libiomp5.so => /opt/intel/ipp/sharedlib/libiomp5.so (0xb6ffc000)
/lib/ld-linux.so.2 (0xb77ce000)[/bash]
so, my program correctly find libraries that it needs to run, but the runtime error remains there!

2. moreover, the paths in LD_LIBRARY_PATH are correct:

[bash]echo $LD_LIBRARY_PATH 
/opt/intel/ipp/sharedlib:[/bash]

Hello,

It looks that the CPU optimized libraries are missed in your folder:

For example, libipps.so.7.0 is dispatch library, which will dynamically load the following CPU optimized library according the CPU types at runtime:

libippsg9.so.7.0
libippsv8.so.7.0
ibippsp8.so.7.0
libippsw7.so

....

Similarly, libippi.so.7.0 libippcc.so.7.0 libippcv.so.7.0 also needs their CPU optimized library.
Copy others libraries at /ipp/lib/ia32 folder, and check if it can resolve the problem.

Thanks,
Chao

Hello. I have the same problem - my application depends on ippcore, ipps, ippsc, all paths are correct, but I receive "Error at loading of ippSC library ...". I didn't copy any libraries from ipp/lib/ia32 anywhere after the installation.

Here's the list of ippcore, ipps and ippsc libraries in this folder. Is there anything missing?

So, now I found out that my processor must support "p8" libraries, and they are on their place. Maybe something caused wrong architecture detection?

Hello,

What is the processor you are running?

If you use the following command line:
>export LD_LIBRARY_PATH

Do you see similar IPP library path is included?

/opt/intel/composerxe-2011.x.xxx/ipp/lib/ia32

If not, please try to use the command line like the following to set the IPP environment?

>source /opt/intel/composerxe-2011.x.xxx/ipp/bin/ippvars.sh ia32

Thanks,
Chao

My processor is i3 330M.

I tried to use this script, so now I have this path included in /etc/ld.so.conf, but this error still occurs.

Hi,

Could you attach the executable file here? I am tryingtoreproduce the problem here.

Hello,

Thanks for the test file. I can saw the Waterfall error. It is likely that the compiler runtime libraries are missed there. The libraries at the folder /opt/intel/composerxe-2011.x.xxx/ipp/../compiler/lib/ia32 are also needed by your application:

For example, whenadding the environment:

export LD_LIBRARY_PATH=/opt/intel/composerxe-2011.1.036/ipp/../compiler/lib/ia32:/opt/intel/composerxe-2011.1.036/ipp/lib/ia32:/opt/intel/composerxe-2011.1.036/ipp/lib/ia32

The code works fine. But when usingthe following environment, it got the waterfall error:

export LD_LIBRARY_PATH=/opt/intel/composerxe-2011.1.036/ipp/lib/ia32


Thanks,
Chao
