Creating a customdylib

[apolo74]

I have created a customso of the IPP functions that I'm using in my application for linux 32 and linux 64, but I'm having problems creating the MacOS version of this. The non-threaded version for 32- and 64bit seems to be created after hundreds of warnings of the type:

ld: warning: could not create compact unwind for _m7_ippiConvValid_32f_C1R: register saved more than once (might be shrink wrap)

The threaded version fails after the same hundreds of warnings similar to the example above:

Undefined symbols for architecture x86_64:

"__intel_fast_memcpy", referenced from:

_m7_ippiCopyConstBorder_32s_C1R in libippi_t.a(piconstlbordca_split_m7_ippiCopyConstBorder_32s_C1R.o)

In my application I'm using functions from ipps, ippi and ippvm so I have modified the Makefile.intel64 and Makefile.ia32 to include those libraries:

ifdef THR_SFX

IPPLIB := ippi_t ipps_t ippvm_t ippcore_t

ILIB := $(LIBPTHREAD)

else

IPPLIB := ippi_l ipps_l ippvm_l ippcore_l

endif

Is there something else I should do for MacOS? Thanks in advance for your help,

Boris

Hello apolo74.

The error messsage

"Undefined symbols for architecture x86_64:

"__intel_fast_memcpy" looks familiar.

Would you like to try add libirc*.under compiler lib folderand see if you can work around the issue?
