安卓 OpenCV - "error: cannot find -lopencv_java"

Question

我正在尝试使用IntelliJ IDEA 13.1.4开发OpenCV本地代码。当我尝试ndk构建mixedprocessing示例中提供的代码时，我有这个错误:

[armeabi-v7a] Compile++ thumb: com_sample_jniLib <= com_sample_jniLib.cpp
[armeabi-v7a] SharedLibrary  : libcom_sample_jniLib.so
D:/Workspace/android-ndk-r10/toolchains/arm-linux-androideabi-4.6/prebuilt/windows-x86_64/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld.exe: error: cannot find -lopencv_java
make.exe: *** [obj/local/armeabi-v7a/libcom_voxar_tracker_TrackerLib.so] Error 1
D:Workspaceandroid-ndk-r10sourcescxx-stlstlportstlport

基本上，他找不到-lopencv_java。

这是我的Android.mk:

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
include jni/opencv/OpenCV.mk
LOCAL_SRC_FILES := com_voxar_tracker_TrackerLib.cpp
LOCAL_MODULE := com_voxar_tracker_TrackerLib
LOCAL_LDLIBS +=  -llog -ldl
include $(BUILD_SHARED_LIBRARY)

和Application.mk:

APP_STL := stlport_static
APP_CPPFLAGS := -frtti -fexceptions
APP_ABI := all

正如我之前所说的，我在Windows 8.1上使用IntelliJ IDEA 13.1.4， OpenCV 2.4.9和Android NDK r10 32位。有人知道这是什么吗?

你似乎忘记了OPENCV_INSTALL_MODULES:=on在你的Android.mk:

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
OPENCV_INSTALL_MODULES:=on
include jni/opencv/OpenCV.mk
LOCAL_SRC_FILES := com_voxar_tracker_TrackerLib.cpp
LOCAL_MODULE := com_voxar_tracker_TrackerLib
LOCAL_LDLIBS +=  -llog -ldl
include $(BUILD_SHARED_LIBRARY)
