Unreferenced function even if it's in a linked library

Hi guys.
I'm blocked with this error:

target StaticExecutable: sdcard (/home/Ubuntu/javier/dati/download/part-tree/out/target/product/y991/obj/EXECUTABLES/sdcard_intermediates/LINKED/sdcard)
/home/Ubuntu/javier/dati/download/part-tree/out/target/product/y991/obj/STATIC_LIBRARIES/liblogwrap_intermediates/liblogwrap.a(logwrap.o): In function `do_log_line':

This is the interesting part of the Android.mk for liblogwrap

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

# ========================================================
# Static library
# ========================================================
include $(CLEAR_VARS)
LOCAL_MODULE := liblogwrap
LOCAL_SRC_FILES := logwrap.c
LOCAL_SHARED_LIBRARIES := libcutils liblog
LOCAL_EXPORT_C_INCLUDE_DIRS := $(LOCAL_PATH)/include
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include
LOCAL_CFLAGS := -Werror
include $(BUILD_STATIC_LIBRARY)

This is the grep matching the function not found inside ./target/product/y991/obj/SHARED_LIBRARIES/libcutils_intermediates/LINKED/libcutils.so

nm -C ./target/product/y991/obj/SHARED_LIBRARIES/libcutils_intermediates/LINKED/libcutils.so | grep klog_write
000000000000a504 T klog_write

Why it can't find that?
