How to statically link the threaded IPP 6.0 libraries libipp*_t.a

"gcc -m32 -o test_static_mt -DIPP_MULTITHREAD_LZO test_static.c -lippdcemerged -lippdcmerged_t -lippsemerged -lippsmerged_t -lippcore_t -liomp5 -lpthread"

How to resolve the following link errors? Thanks in advance.

You need to add the following runtime libraries into the command line for static threaded libraries:
libimf.a libsvml.a libirc.a

For example,
-lippdcemerged -lippdcmerged_t -lippsemerged -lippsmerged_t -lippcore_t -limf -lsvml -lirc -liomp5 -lpthread

Thanks,
Chao
