Abhängig von meiner ersten question, habe ich versucht, die fanotify.h
Header in meiner Anwendung zu integrieren. Die Anwendung basiert auf fsmon (eine kleine Anwendung, die fanotify syscall zu verwenden), änderte ich einige Code-Zeilen für meine Zwecke und schuf eine Android.mk Make-Datei:Android ndk Build kann nicht 32bit ausführbare Datei erstellen
APP_PLATFORM := android-23
TARGET_PLATFORM := android-23
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# Enable PIE manually. Will get reset on $(CLEAR_VARS). This
# is what enabling PIE translates to behind the scenes.
LOCAL_CFLAGS += -fPIE -DHAVE_FANOTIFY=1 -DHAVE_SYS_FANOTIFY=0
LOCAL_LDFLAGS += -fPIE -pie
# give module name
LOCAL_MODULE := fsmon
# include fanotify by api 23:
LOCAL_C_INCLUDES := /home/fabian/Android/Sdk/ndk-bundle/platforms/android-23/arch-arm/usr/include
# include fanotify by sysroot ->
# LOCAL_C_INCLUDES := /home/fabian/Android/Sdk/ndk-bundle/sysroot/usr/include/
# list your C files to compile
LOCAL_SRC_FILES := inotify.c fanotify.c util.c main.c
# this option will build executables instead of building library for android application.
include $(BUILD_EXECUTABLE)
Ich brauche die linux/inotify.h
und die linux/fanotify.h
Header enthalten .
Auf ndk-build
Ausführung nur die arm64-v8a
, mips64
und x86_64

Ursache inotify.c
die signal.h
Header enthält, die die Wieder enthält linux/signal.h
und dies wiederum die platforms/android-9/arch-arm/usr/include/asm/signal.h
, wo der Fehler auftritt. (plötzlich von Android-9).
Ich kann nicht herausfinden, wo das Problem ist .. Ich habe versucht, den Include-Ordner von Sysroot - aber ähnliche Fehler erscheinen.
Quelldatei: inotify.c fanotify.c
Wow, vielen Dank !! Ja das war das Problem ... diese einfache Zeile war in der Application.mk notwendig. Jetzt funktioniert es! – Fabman22
