我要编译delegate在带有 NDK 构建器的 Android 中(在 Windows 中)。
DeleGate是一个多用途代理服务器，用于在多个平台上运行的多个应用程序协议(protocol)。本文档的目的是通过一系列使用示例和针对初学者的简短教程来介绍如何使用 DeleGate。
我是 NDK 的新手，任何线索都会有所帮助。
这是完整的错误:

最佳答案
这不是 NDK 独有的:可执行文件需要有一个 main 函数。您是要构建库还是可执行文件？对于 NDK，您几乎总是需要一个库。为此，您应该使用 BUILD_SHARED_LIBRARY 而不是 BUILD_EXECUTABLE。如果你想要一个可执行文件，添加一个 main 函数。
