使用gralloc_priv.h文件编译时出错

Question

编程的新手，所以对我容易。 我在为AOSP rom进行编译时收到错误。 我做这一切在Ubuntu 12.04内核3.2.0.29有没有什么帮助任何。

这是我收到的错误：

device / lge / c800 / include / gralloc_priv.h：在成员函数“ T＆Queue :: getHeadValue（）\\> const”中：device / lge / c800 / include / gralloc_priv.h：169：55：错误：没有参数到>取决于模板参数的'LOGE'，因此'LOGE'声明必须可用[-fpermissive] device / lge / c800 / include / gralloc_priv.h：169：55：注意：（如果使用'- fpermissive'，G ++将>接受您的代码，但已禁止使用未声明的名称）

这是与头文件相关的代码部分：

如果有人可以帮助解决此错误并向我解释，将非常有帮助。 如果需要更多信息，我将发布所需信息。 我可能会在这里发布更多错误，但想看看我如何处理第一篇文章。 在此先感谢所有。

您可以在gralloc_priv.h之前gralloc_priv.h在代码中包含#include <cutils/log.h>吗？

或根据错误输出提示使用参数-fpermissive编译。
