将 cocos2d-x win32 项目移植到 Android 时出错？答案

【问题标题】：error porting cocos2d-x win32 project to Android?将 cocos2d-x win32 项目移植到 Android 时出错？
【发布时间】：2014-04-10 09:11:07
【问题描述】：

我在 cocos2d-x win32 项目上工作了很长时间。新的我想将我的项目移植到 Android 项目。我将proj.android 导入Eclipse 并解决了一些错误。不幸的是，我不小心删除了project properties>C/C++ general>Paths and Symbols>Includes 下的一些includes。现在我遇到了这个错误。我该如何解决。我正在使用 cocos2d-x 2.1.5 和 Android NDK r8e。

【解决方案1】：

error: undefined reference to 可能是由于您的Android.mk 中包含不正确的内容

我相信你在包含静态库的地方犯了语法错误：

LOCAL_WHOLE_STATIC_LIBRARIES += cocos2dx_static

应该是：

LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_static

【讨论】：

您在声明APP_CFLAGS += -Wno-error=format-security 中也有问题。在此处将 + 替换为 :。您是使用 eclipse 构建项目还是仅使用命令构建 NDK 项目？在构建项目之前，您是否清理了所有旧的 obj 文件？
