Hi, I'm a bit of a newbie to C and embedded programming. I'm using the ARM Crossworks IDE right now and trying to get the HRM_RX example working on my PCA10028 board. I've imported the code and when ever I attempt to compile it, I get the following errors from the retarget.c file.

error: storage size of '__stdout' isn't known

error: storage size of '__stdin' isn't known

From my reading I understand I have to define the size of these two as Crossworks doesn't do it for me, but I'm at a bit of a loss as to how to do that correctly. Any help is appreciated!
