我正在尝试将 XMP 工具包移植到 Android 设备。我能够成功构建 xmpcore,并拥有一个 libXMPCore.so。当我尝试使用 ndk-build 制作 libXMPFile.so 时,我遇到了几个我不明白的问题。

1) libXMPFile.so 似乎依赖于 libXMPCore.so。我设法在 libXMPFiles 的 Android.mk 中包含了 libXMPCore.so。我的 Android.mk 看起来像这样:

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_CPPFLAGS := -std=c++0x
LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../../../../../../android-ndk-r8e/sources/cxx- stl/gnu-libstdc++/4.6/libs/x86/include
LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../../../../../../android-ndk-r8e/sources/cxx- stl/gnu-libstdc++/4.6/include
LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../../../../../../

LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../XMPFilesPlugins/api/source

LOCAL_LDLIBS := $(LOCAL_PATH)/../obj/local/armeabi-v7a/libXMPCore.so

LOCAL_MODULE := xmpfile
LOCAL_MODULE_TAGS := optional
include $(BUILD_SHARED_LIBRARY)

但是,当我尝试运行 ndk-build 时,它会提示链接错误,例如:WXMPFiles.o: 在函数 WXMPFiles_GetXMP_1:/home/w18656/workspace/xline2/main-jb-qcpro-4.2-xline/motorola/hal/ispbypass/xmp/XMP-Toolkit-SDK-CS6/XMPFiles/jni/../source/WXMPFiles.cpp:288: 错误:对'TXMPMeta, std::allocator >>::TXMPMeta(XMPMeta*)' 的 undefined reference

对于 TXMPMeta 类的实现,我很困惑。似乎定义在 TXMPMeta.hpp 中,类的实现在 client-glue/TXMPMeta.incl_cpp 中。

但是,我检查了 XMPFiles.mak,TXMPMeta.incl_cpp 不是我们编译的文件之一。我们如何编译类 TXMPMeta 的实现? (与其他 TXMPxxx.incl_cpp 相同的问题)

我正在使用 8e android NDK,并尝试为 XMPCore 和 XMPFiles 构建本地共享库。

感谢您的帮助。

最佳答案

我想我设法通过对源代码的一些修改为 android 编译它,查看这个项目:

https://github.com/janrueegg/xmp

以下是如何为 android 编译它,确保将 ANDROID_NDK 设置为正确的路径。

git clone https://github.com/janrueegg/xmp.git
cd xmp/build
export ANDROID_NDK=~/my-android-ndk
make StaticReleaseAndroid
mkdir -p xmp/lib
cp -r ../public/include/ xmp/
cp ../public/libraries/i80386linux/release/*.ar xmp/lib

这应该会为您提供一个名为“xmp”的文件夹,其中包含静态库和一个包含 header 的包含文件夹。

只需使用此包含路径进行编译并链接到给定的库...
