Linking errors with libipps_t.a

[Bo_Fang]

Hi all,

I am having a problem with linking to IPP threaded libraries, particularly IPP signal processing library ( libipps_t.a and lippcore_t.a). The single thread versions work fine.

Here are the error message:

/opt/intel/ipp/lib/ia32/libipps_t.a(psmagn_split_p8_ownippsMagn_64fc64f_omp.o): In function `p8_ownippsMagn_64fc64f_omp':

psmagn_split_p8_ownippsMagn_64fc64f_omp.i:(.text+0x4f): undefined reference to `__kmpc_global_thread_num'

psmagn_split_p8_ownippsMagn_64fc64f_omp.i:(.text+0xb3): undefined reference to `__kmpc_serialized_parallel'

....

I am using GCC 4.4 and IPP 7.0 on Ubuntu 10.04. I have enabled openmp in the flags using -fopenmp. The single thread version was working fine with OpenMP but I have needs to enable threaded versions of FFTs, so I plan to use threaded IPP functions.

Thanks in advance
