Application.mk文件：
APP_ABI := armeabi-v7a
#APP_ABI := armeabi
APP_PLATFORM = android-19
Android.mk文件：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := poison
LOCAL_SRC_FILES := poison.c
LOCAL_LDLIBS += -L$(SYSROOT)/usr/lib -llog
include $(BUILD_EXECUTABLE)
使用ndk-build编译后，输出文件为poison，把程序push到虚拟机，chmod 0777执行，提示"not executable: magic 7F451"
IDA自带的android_server在虚拟机中可以执行，用readelf查看文件信息发现android_server和poison文件的Type类型一个是"EXEC (Executable file)"一个是"DYN (Shared object file)"，不知道是否由于这个问题导致poison无法执行，如果是的话，请问该如何修改才能让程序可执行呢？
