我正在尝试在一个新的应用程序中使用Mecab，但我无法使该库正常工作。最初，我尝试了以下应该与iOS 6兼容的存储库:
https://github.com/gumob/mecab
我尝试构建通用二进制文件，然后添加库和头文件，以及简单地将整个项目添加为依赖项，但是在两种情况下，我最终都遇到很多错误。所以，我放弃了那个，回到原来的分支:
https://github.com/FLCLjp/iPhone-libmecab
我相信它最初是为iOS 3制作的。但是，如果您对该存储库中包含的示例应用程序进行了以下更改，则该应用程序将在iOS 9.3模拟器和设备上构建并运行:
将应用程序委托(delegate)中的第26行更改为
[self.window addSubview:viewController.view];
至
[self.window setRootViewController:viewController];
将“其他来源”文件夹中的mecab.xcodeproj中找到的LibMecabSample目标和mecab库目标的“build设置-体系结构”选项更改为“标准体系结构(armv7 arm64)”。
由于此版本似乎可以正常工作，因此我尝试将在该存储库中找到的mecab.xcodeproj实现到我的应用中。我基本上只是尝试重新创建它在LibMecabSample应用程序中的实现方式，而且一切似乎都是相同的。我什至在文本程序中对xcode项目文件进行了差异化处理，以确保build设置没有任何差异。有几个区别(ARC，启用模块和用户定义的PREBINDING-无设置)，但是更改它们似乎并没有影响，并且在尝试构建时仍然出现以下错误:

我不确定这仅仅是链接器问题还是与C编译器有关，但是我已经花了几天的时间进行修补，但似乎无法弄清楚。如果有人可以提供提示，我将非常感激。
最佳答案
花了几个小时弄清楚了，但我知道了。一旦知道了步骤，实际上并没有那么困难。
好的，首先，手动将mecab文件夹复制到您的项目文件夹(否则将无法正常工作。然后右键单击项目的顶部树对象，然后选择“添加文件”。
在mecab文件夹中选择mecab.xcodeproj文件。它应该已经添加到您的项目树中，以及它的子文件夹，然后是所有类。
然后将Mecab.h/.m和Node.h/.m文件拖到您的项目中，确保选择复制它们。
然后转到项目的目标，并在build phases中添加这三个库。
然后转到build settings中的“标题搜索路径”，并将路径添加到您的mecab文件夹中。如果像我一样将其复制到项目的文件夹中，则它将看起来像这样。
然后将IPADic文件夹拖到您的项目中，注意不要将其放在mecab.xcproj子文件夹下。您希望在主捆绑包中找到它，否则mecab将找不到它。
然后清理并构建。它应该工作。我刚刚将其添加到应用程序委托(delegate)中，并向其提供了测试字符串，然后设置了断点。有效!
关于c++ - 将较旧的Mecab库实现到现代iOS应用中，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/37405004/
