android - 静态链接OpenCV 2.4.3.2

Question

我想将OpenCV(2.4.3.2)静态链接到我的项目。现在我的Android.mk看起来像这样

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on

include /Users/jamiematthews/Documents/Android-Projects/OpenCV-2.4.3-android-sdk/sdk/native/jni/OpenCV.mk

LOCAL_MODULE    := jni_part
LOCAL_SRC_FILES := jni_part.cpp
LOCAL_LDLIBS +=  -llog -ldl
LOCAL_LDLIBS += -L$(SYSROOT)/usr/lib -llog 
include $(BUILD_SHARED_LIBRARY)

引发错误:

Android NDK: ERROR:/Users/jamiematthews/Documents/workspace/AuthentiGuard/jni/Android.mk:on: LOCAL_SRC_FILES points to a missing file    
/Users/jamiematthews/Documents/android-ndk-r8d/build/core/prebuilt-library.mk:43: *** Android NDK: Aborting    .  Stop.
Android NDK: Check that /Users/jamiematthews/Documents/Android-Projects/OpenCV-2.4.3-android-sdk/sdk/native/jni/../libs/mips/libon.so exists  or that its path is correct

有人知道“LOCAL_SRC_FILES指向丢失的文件”是什么意思吗？

PS，如果我删除线

OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on

它编译正常，但是我不能静态链接

Answer 1

找到了解决方案。信不信由你，这是Application.mk的问题，而不是Android.mk的问题。我已经设定

APP_ABI := all

以前，甚至没有考虑过它可能会静态影响此构建过程。我最终将其更改为

APP_ABI := armeabi-v7a

现在，一切正常。请注意，我最终不需要OPENCV_CAMERA_MODULES:= on，我相信仅当您从JNI调用摄像机时，我才不需要
