使用gralloc_priv.h文件编译错误 [英] Error compiling with gralloc_priv.h file

问题描述

新的编程，所以容易在我。我在编译AOSP rom时收到错误。我做所有这一切在Ubuntu 12.04内核3.2.0.29如果这有助于任何。

New to programming so be easy on me. I'm receiving an error while compiling for an AOSP rom. I'm doing all of this on Ubuntu 12.04 kernel 3.2.0.29 if that helps any.

这是我收到的错误：

device / lge / c800 / include / gralloc_priv.h：在成员函数'T& Queue :: getHeadValue（）\> const'：
device / lge / c800 / include / gralloc_priv.h：169：55：错误：没有参数'LOGE'>依赖于模板参数，所以必须提供一个LOGE的声明[-fpermissive]
device / lge / c800 / include / gralloc_priv.h：169：55：注意:(如果你使用'-fpermissive'，G ++会接受你的代码，但允许使用未声明的名称已弃用）

device/lge/c800/include/gralloc_priv.h: In member function 'T& Queue::getHeadValue()\ > const': device/lge/c800/include/gralloc_priv.h:169:55: error: there are no arguments to 'LOGE' that > depend on a template parameter, so a declaration of 'LOGE' must be available [-fpermissive] device/lge/c800/include/gralloc_priv.h:169:55: note: (if you use '-fpermissive', G++ will > accept your code, but allowing the use of an undeclared name is deprecated)

如果任何人可以帮助解决这个错误， 。如果需要更多信息，我会发布任何所需的。我可能会在这里发布更多的错误，但想看看我如何做这第一篇文章。感谢所有的提前。

If anyone can help with this error and explain it to me would be very helpful. If more info is needed I will post whatever is needed. I will probably be posting a few more errors here but wanted to see how I do with this first post. Thanks to all in advance.

推荐答案

您可以尝试并加入 #include< cutils / log.h>

或使用参数编译时，在代码 fpermissive 作为错误输出建议。

or compile with parameter -fpermissive as the error output suggests.
