【问题描述】：

我将 MailCore2 用于邮件 Android 应用程序。我按照文档 (https://github.com/MailCore/mailcore2/tree/master/build-android) 中提供的构建说明进行操作。

$ export ANDROID_SDK=/path/to/android-sdk
$ export ANDROID_NDK=/path/to/android-ndk
$ cd build-android
$ ./build.sh

我收到这些消息：

CMake Error at CMakeLists.txt:80 (message):

它生成二进制文件mailcore2-android-version.aar，如文档中所述，但我不能在我的项目中使用它。每次我尝试使用 mailcore 库的功能时它都会崩溃。

有什么想法吗？

【问题讨论】：

你必须得到 ctemplate: "ERROR: Could not find ctemplate"
是的，我找不到它的来源。我搜索了很长时间，但似乎没有人有类似的问题。我不知道 ctemplate 是什么以及它的用途。所以，如果有人能在这个特定的错误上给我一个线索，那就太好了......

标签： android android-library mailcore2

【解决方案1】：

如果这是在 Mac OS X 上，您可以下载缺少的组件 CTemplate (here) 和 Libetpan (here；如果稍后弹出该错误）。安装这些组件为我解决了这些错误。

【解决方案2】：

有点晚，但可能对未来的用户有用：

在build-android/includes 中创建一个“MailCore”目录。然后从src/ 目录执行（对于 OS X）：

cp `find . -name '*.h'`  ../build-android/includes/MailCore/

它对我有用！

【讨论】：

感谢您的提示，但我必须将所有头文件复制到“include”文件夹中，而不是“includes”。然后它起作用了。
