我尝试使用以下链接将 HockeyApp 集成到我的 cocos2d-x 项目中：- http://support.hockeyapp.net/kb/client-integration-android/hockeyapp-for-android-ndk-early-access

但是当我尝试运行 ndk-build 命令时出现以下错误

【问题讨论】：

能否告诉我您在哪个平台上调用了 ndk-build？你用的是哪个编译器？我仍在尝试重现您的问题，我会尽快回复您。同时，也许您可以尝试在 ndk 上启用 c++11 支持，通过在 Application.mk 文件中添加“APP_CPPFLAGS += -std=c++11”来编译您的应用程序。

【解决方案1】：

GCC 4.6.3 不支持 C++11 类型别名：

在

Breakpad\src\client\linux\log\log.cc

替换

using AndroidLogBufferWriteFunc = int (*)(int bufID, int prio, const char *tag,const char *text);

与

typedef int (*AndroidLogBufferWriteFunc)(int bufID, int prio, const char *tag,const char *text);
