Following wiki at the end I get:
`user@machine ~/projects/esp8266/esp-open-rtos/examples/punyforth/arch/esp8266/rtos/user $ make CC /home/user/projects/esp8266/esp-open-rtos/open_esplibs/libmain/user_interface.c /home/user/projects/esp8266/esp-open-rtos/open_esplibs/libmain/user_interface.c:14:23: fatal error: lwip/dhcp.h: No such file or directory
include "lwip/dhcp.h"
compilation terminated. make: *** [../../../../../../open_esplibs/component.mk:17: build/open_esplibs_libmain//user_interface.o] Error 1 `
Do I need to set other environment variables?
