IPP 8 legacy code sample link issue

Mark_H_9 — Wed, 20 Nov 2013 12:59:34 GMT

Dear all

I am trying to build a linux speech codec program based on intel IPP 8 code samples.

My code is quite simple and only include "usc.h" and "usc_objects_decl.h"

The compile is successful, but when trying to do the link, I can't find the libspeech.a library

My question is how to static link my code with intel speech codec samples library?

I had stuck on this issue for several days, and not clues to complete the linkage job, and the code is very very important to me.

Thank you very much, Sir!

I built code samples followed by below steps:

-----------------------------------------------------------------------------------------------------------------------------

! winscp copy l_ipp_8.0.0.061.tgz to /tmp

cd /tmp
tar -zxvf l_ipp_8.0.0.061.tgz

setsebool allow_execmod on
setsebool allow_execstack on

./install.sh

setsebool allow_execmod off
setsebool allow_execstack off

Hi Mark,

Hi Mark,

How do you link your application? Could you show the command line?

Regards,
Sergey

Hi Mark,

Ying_H_Intel — Thu, 21 Nov 2013 08:12:33 GMT

Hi Mark,

You can link the static library as the below two test cases. . The libspeech.a is from old versions. ( archive all of *.a into speech.a). The 8.0 use seperate codec, thus if you need one kind of codec (i.e g729fp), you can just link one libspeech_g729fp.a.

Best Regards,
Ying

Thank you very much, Sergey and Ying!

Hi Ying

Hi Ying

I know how to link now.

Hi Mark,

Sergey_K_Intel — Fri, 22 Nov 2013 04:30:11 GMT

Hi Mark,

It can be a workaround. There should be no object files with the same names, so this extract/combine operation should be safe.

Otherwise, you need to experiment with command line to linker "g++ -static -o ...", specifying the required libraries with "-l" option.
BTW, there's something wrong with the linker command line. It must be

g++ -static -o main main.o Packets_Processing.o codec.o -L. -l$libspeech -L $ippdir $IPPLIB

i.e. "-l" (lower L) before $libspeech. Or, add "-l" to export command.

Regards,
Sergey

Hi Sergey

Mark_H_9 — Fri, 22 Nov 2013 08:56:00 GMT

Hi Sergey

-L. followed with dir + filename ==== -L dir -l library-name

It at least works for g++.

Finally, I got my link working!

Thank you very much!
