我目前無法編譯dirent.h函數，如opendir（）。我做了什麼？我相信我有這個工作。Android dirent.h opendir（）不會編譯
Android_Utils.cpp：
#include <dirent.h>
void Test1237(void)
{
struct DIR *dir = opendir("blah");
}
我Android.mk文件：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := SDL2-prebuilt
LOCAL_SRC_FILES := /work/SDL2/lib-android/$(TARGET_ARCH_ABI)/libSDL2.so
include $(PREBUILT_SHARED_LIBRARY)
# --------------------------------------------------------------------------------------------------
JNI_LIBPATH := /work/TT/android-TT/jniLibs
include $(CLEAR_VARS)
LOCAL_MODULE := libfreetype2
LOCAL_SRC_FILES := /work/FreeType2/Android/$(TARGET_ARCH_ABI)/libfreetype2-static.a
include $(PREBUILT_STATIC_LIBRARY)
# --------------------------------------------------------------------------------------------------

LOCAL_MODULE := main

ifeq ($(TARGET_ARCH_ABI),$(filter $(TARGET_ARCH_ABI), armeabi-v7a x86))
LOCAL_CFLAGS := -DHAVE_NEON=1 $(MY_CFLAGS) -Wno-write-strings -Wno-trigraphs
