I am trying to compile a program (gcc, using some functions from intel's ipp library). It is my first use of ipp, so I think I might be doing some not very clever mistake. Anyhow:

g++ -o inteltrial inteltrial.cpp -I/home/me/Desktop/work/p1/geqw4/vi3/out/sp/ccode/eigen -I/opt/intel/composerxe/ipp/include -L/opt/intel/composerxe/ipp/lib/intel64/ -libipps_l.a -libipps_t.a


/usr/bin/ld: cannot find -libipps_l.a
/usr/bin/ld: cannot find -libipps_t.a

now, -libipps_l.a -libipps_t.a are in /opt/intel/ipp/lib/intel64

How to point gccto the right location?


This post seems to be related, but I can't find on the internet how to add a line to ld.so.conf....

What the error you see is saying is that the program ld cannot find those files. The /usr/bin/ld: part identifies what is throwing the error, not where the checks for the files are occurring.

ok thanks.....now, how to show gcc where those files are? –  user2413 Jul 19 '12 at 13:48
@user2413 I am not familiar with how to fix the gcc compiler's options, so don't mark my answer as the correct answer. I would recommend that you amend your question to say "How can I get the system to find the files?", and just leave this answer as a "This was helpful to explain the error" answer. –  Thomas W.

this did the trick:

export IPPROOT
cd /home/me/Desktop/work/p1/geqw4/vi3/out/sp/ccode
icpc -O3 -o inteltrial inteltrial.cpp -I/home/me/Desktop/work/p1/geqw4/vi3/out/sp/ccode/eigen -I$IPPROOT/include -L$IPPROOT/lib/intel64 -lipps -lippcore
