为什么没有列出Pod？

Question

有没有人成功地将Cocoapods与Boost pod一起使用？

我不明白它似乎没有完全安装。 pod安装到空白项目后，我得到以下内容。我缺少一步吗？

这是我安装的输出

pod install --verbose

为什么没有列出Pod？

这是boost不是Xcode项目的工件，只是一组文件。此外，您会发现boost内部目录位于${PODS_ROOT}/boost内，在构建设置的标题搜索路径中引用。这是你使用Pod获得的。

Pod＆amp;提升层次结构

需要在boost中嵌套../Pods/boost/boost才能允许库中的文件引用自身，如下所示：

#include "boost/date_time/posix_time/posix_time_config.hpp"

如果让操作完成:(压缩时boost库的数量超过100 MB）

Integrating client project

...当你在项目中没有看到它时，你会发现它在源代码树中：

您可以参考：

#import "boost/date_time.hpp"

并开始处理其他紧迫问题，例如找到#include <cstdlib>，这完全是另一个主题。

Objective-C ++编译

为了编译boost，这是一个 C ++ 库，您需要从 C ++ 源文件中显式引用它（不是 C 来源，.m）中的默认值，或采用compiling a C++ class in Xcode: error during compilation: stl vector中列出的替代解决方案。

从.mm文件中，包括以下两个测试行：

#include <cstdlib> // Proof of concept
#import "boost/date_time.hpp"

为了这个例子，我已将main.m重命名为main.mm。由于Pod未导入任何.ipp文件，因此您可以在构建设置中的预处理器宏中添加NO_BOOST_DATE_TIME_INLINE=1。这样做，您将获得大约十几个警告，如下面的警告，以及成功的编译，无需手动导入。

隐式转换失去整数精度：＆＃39; long＆＃39;到＆＃39; hour_type＆＃39; （又名＆＃39; int＆＃39;）

编辑：删除了非主题手动导入，不是必需的
