我想使用AA+ 天文类框架，我只想让示例应用程序运行（它包含在框架 zip 文件中AATest.cpp）

我打开 Xcode，为 C++ 应用程序创建了一个新项目，然后将AA+.h和stdafx.h文件添加到项目中，因为它们包含在内。然后，当我构建项目时，我收到很多链接器错误，因为它似乎无法找到与某些示例应用程序代码关联的符号。

我尝试在 Xcode 的 Build 设置中将路径AA+.h和stdafx.h文件添加到库和标头搜索路径，但这并没有改变任何东西，错误仍然存​​在。

我究竟做错了什么？这是我第一次在 Xcode 中使用 C++。我是否必须首先将 AA+ 框架构建为静态库，或者我可以以这种方式包含它吗？

通过 Xcode 编译：

    cd "/Users/me/Downloads/aaplus astronomy c++/Example/AAPlus"

代码

您可以在 XCode 中执行以下操作：

  1. 创建一个新项目AATest
  2. 将aaplus/包含框架代码的文件夹复制到项目文件夹中
  3. 在您的 XCode 项目中，按住control并单击Source
  4. 选择添加 > 现有文件...
  5. 选择aaplus/文件夹并将其添加到您的项目中
  6. 建造。

可执行文件将在build/Debug/AATest.

选择

由于项目包含一个文件CMakeLists.txt，您可以使用cmake. 在您的框架文件夹中，在终端上运行以下命令：

mkdir build/
cd build/
cmake ..
make
