Same thing here.

ippsLn_32f

is not included in the library, while ippsLn_64f is there.

This is not new, this is in 8.0 and was also in 7.1.1 !

how did you link this example? please look at the ippi.h file - you can find there the declaration of this natural logarithm -- therefore you need to add ippi.lib or ippimt.lib into linking line ( depends on what dynamic or static version you would like to have )

For the 1st one -

you should  also link ippVM library - ippSP and ippIP libraries depend on it.
