There is something wrong when I use the function "ippiRGBToRGB565_8u16u_C3R" in Linux. I compile it with "-L /opt/intel/ipp/6.1.0.039/lp32/lib/ -lippccemerged", but the output is :


/opt/intel/ipp/6.1.0.039/lp32/lib//libippccemerged.a(ippcc00470as.o): In function `ippiRGBToRGB565_8u16u_C3R':

Can anybody help me?Thanks in advance for your answer

It looks that you missed libippccmerged.a and libippcore.a libraries.

please check if the following linkage command line works:
-L/opt/intel/ipp/6.1.0.039/lp32/lib/ -lippccemerged -lippccemerged -lippcore

note, the library order is important in Linux. *merged libraries need to be after *emerged libraries.
