[uClinux-dev] port of user app onto arm

[Marek Bykowski]

Hello All,

It's my first post so wanted to say hello to everybody. I'm doing a port of
user app "opennhrp" onto an arm platform and seems to be running into a
c-ares library problem (Ubuntu package: libc-ares-dev).

Part of my Makefile where I replace standard gcc with arm gcc looks as
below:
#CC := $(CROSS_COMPILE)gcc
#LD := $(CROSS_COMPILE)ld

# !!!!!!!!!!!!!! snapgear replacements !!!!!!!!!!!!!!!!!!!!!!!!!!
#
# snapgear cross-compilation
CC := ucfront-gcc arm-linux-gcc -mbig-endian # ucfront and arm
c compiler and big endian
LD := ucfront-ld arm-linux-ld # ucfront and arm
linker
AR := arm-linux-ar r # binary
utilities for subroutines in archived libs
STRIP := arm-linux-strip # strips the symbols
from object files


when compiling the following error apears:
CC nhrp/admin.o
CC nhrp/libev.o
CC nhrp/nhrp_address.o
nhrp/nhrp_address.c:22:26: ares_version.h: No such file or directory

Have anybody of you came across this problem before?

Thanks a million,
