AndroidNDK，两个静态库和链接

我开始创建共享库，但我认为创建一个共享库和其他静态库更有效。当它被全部共享时，它被编译并链接得很好，但转到静态，我开始链接“未定义的引用”

编辑：我在一个

Android.mk

Android.mk：

MY_LOCAL_PATH := $(call my-dir)
MY_LOCAL_CFLAGS := -DDEBUG

TARGET_PLATFORM := 'android-4'

LOCAL_PATH := $(MY_LOCAL_PATH)/../../Base

include $(CLEAR_VARS)

LOCAL_MODULE     := Base
LOCAL_SRC_FILES  := <Base src files>
include $(BUILD_STATIC_LIBRARY)

MY_LOCAL_STATIC_LIBRARIES := Base

MY_LOCAL_C_INCLUDES := $(MY_LOCAL_PATH)/../../Base

LOCAL_PATH := $(MY_LOCAL_PATH)/../../Framework

include $(CLEAR_VARS)

LOCAL_MODULE     := Framework
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)
LOCAL_SRC_FILES  := <Framework src files>
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)

include $(BUILD_STATIC_LIBRARY)

MY_LOCAL_STATIC_LIBRARIES += Framework

MY_LOCAL_C_INCLUDES += $(MY_LOCAL_PATH)/../../Framework

LOCAL_PATH := $(MY_LOCAL_PATH)/Graphics

include $(CLEAR_VARS)

LOCAL_MODULE    := Graphics
LOCAL_SRC_FILES := <Graphics src files>
LOCAL_EXPORT_LDLIBS := -lGLESv1_CM
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)

include $(BUILD_STATIC_LIBRARY)

MY_LOCAL_STATIC_LIBRARIES += Graphics

MY_LOCAL_C_INCLUDES += $(MY_LOCAL_PATH)/Graphics

LOCAL_PATH := $(MY_LOCAL_PATH)/Platform

include $(CLEAR_VARS)

LOCAL_MODULE := Platform
LOCAL_SRC_FILES := <Platform src files>
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)

include $(BUILD_STATIC_LIBRARY)

MY_LOCAL_STATIC_LIBRARIES += Platform

MY_LOCAL_C_INCLUDES += $(MY_LOCAL_PATH)/Platform

LOCAL_PATH := $(MY_LOCAL_PATH)

include $(CLEAR_VARS)

LOCAL_MODULE    := Final
LOCAL_SRC_FILES := <Final src files>
LOCAL_STATIC_LIBRARIES := $(MY_LOCAL_STATIC_LIBRARIES)
LOCAL_LDLIBS    := -llog
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)

include $(BUILD_SHARED_LIBRARY)

Edit2:TextureRenderer包含在图形中，包括在内

有人知道它为什么不工作以及如何修复吗？

在您的

Android.mk

中，请确保使用正确的调用引用静态库：

LOCAL_STATIC_LIBRARIES := mystaticlibproj

调用include

$（构建共享库）

之前

然后，在文件的末尾，调用导入静态lib模块

$(call import-module, mystaticlibproj)

---

如果您仍然有问题，请发布详细的构建日志（

ndk build V=1-B

）和您的

Android.mk

，这看起来像是链接问题的顺序

您的命令行是：

arm-linux-androideabi-g++ -Wl,-soname,libFinal.so -shared \
  libBase.a libFramework.a libGraphics.a libPlatform.a -o libFinal.so

错误是

libPlatform.a(ATexture.o): In function `ATexture':
ATexture.cpp:9: undefined reference to `TextureRenderer'
ATexture.cpp:9: undefined reference to `TextureRenderer'

TextureRenderer在图形中。但是libGraphics在命令行中位于libPlatform之前。g++将在命令行中按照给定的顺序搜索每个库，加载函数以解析外部引用。它将读取一次libGraphics，加载解析外部引用的函数，然后移动到libPlatform

---

尝试将

LOCAL\u STATIC\u库：=$（MY\u LOCAL\u STATIC\u库）

更改为

LOCAL\u STATIC\u库：=Platform Graphics Framework Base

，看看你的进展如何。

我应该提到，我在一个Android中编译了所有库。首先，我要仔细检查Texturenderer是否确实在libGraphics.a中，虽然可能是。使用/Users/robbie/Library/Frameworks/Android NDK/toolschains/arm-linux-androideabi-4.4.3/prebuild/darwin-x86/bin/arm-linux-androideabi-nm在库中转储符号一个共享库比多个共享库有什么好处，除了必须键入更多的System.loadLibrary（）？我没有你的问题，我只是不知道如何生成链接的静态库。谢谢你的例子。

libPlatform.a(ATexture.o): In function `ATexture':
ATexture.cpp:9: undefined reference to `TextureRenderer'
ATexture.cpp:9: undefined reference to `TextureRenderer'
