Problems with spresense

Hi

I'm trying to compile some configs for my spresense board.

"spresense:nsh" runs without problems, but when I try to compile some 
configurations for the *camera* I have the following error:

CC:  video/v4l2_cap.c In file included from 
/home/bucher/sviluppo/NUTTX/nuttx/include/nuttx/video/v4l2_cap.h:29,

I tried nuttx from official git and from the spresense sdk, but the 
results are identical
