gcc ipp1.c -o ipp1.o -I$(IPPROOT)/include/ $(IPPROOT)/lib/libippmmergedem64t.a $(IPPROOT)/lib/libippmemergedem64t.a $(IPPROOT)/lib/libippiemergedem64t.a $(IPPROOT)/lib/libippsemergedem64t.a $(IPPROOT)/lib/libippimergedem64t.a $(IPPROOT)/lib/libippsmergedem64t.a $(IPPROOT)/lib/libirc.a $(IPPROOT)/lib/libsvml.a $(IPPROOT)/lib/libimf.a $(IPPROOT)/lib/libiomp5.a $(IPPROOT)/lib/libippcoreem64t.a -lm -lpthread

The error message is as follows :

I am using the method 'ippmAdd_mm_64f' for marix-matrix addition.

Kindly help me on this.

Thanks & Regards.

Hello,

as far as I know the order of libraries in linker command line does matter for Linux linker. So I would suggest you to change the order of ippm libraries - please try to set first libippmemerged.a and set libippmmerged.a as a second library.

Regards,
Vladimir

Hi prakrati!

"emerged" library have to set before corresponded "merged" library, please try this line:

gcc ipp1.c -o ipp1.o -I$(IPPROOT)/include/ $(IPPROOT)/lib/libippmemergedem64t.a $(IPPROOT)/lib/libippmmergedem64t.a $(IPPROOT)/lib/libippiemergedem64t.a $(IPPROOT)/lib/libippimergedem64t.a $(IPPROOT)/lib/libippsemergedem64t.a $(IPPROOT)/lib/libippsmergedem64t.a $(IPPROOT)/lib/libirc.a $(IPPROOT)/lib/libsvml.a $(IPPROOT)/lib/libimf.a $(IPPROOT)/lib/libiomp5.a $(IPPROOT)/lib/libippcoreem64t.a -lm -lpthread

It should work

Hi,

Pavel is right, we are also mentioned same in the Simplified Link Instructions for the IPP Library article.

the order of the link list is important for static libraries in a Linux environment, since many of the linkers used in this environment default to operating in a single-pass mode. In this case it is best to order the library files according to the following rule: *emerged.a first, followed by *merged.a and ending with ippcore.a.
