使用 Stock Android (Froyo) 时出现编译错误？

Question

我正在尝试从 Nexus One 的源代码编译 Android (Froyo)。我几乎遵循了此处的所有说明。

虽然说明适用于 Gingerbread，但我并没有真正看到 Froyo 有多大区别。在我执行“make -j4”后，抛出以下错误：

有人可以帮我解决这个问题吗？

Answer 1

该函数在 Froyo 中名为 getCameraInfo()，但在 Gingerbread 中更改为 HAL_getCameraInfo()。因此，从 Froyo 机器提取的动态库 libcamera.so 在 Gingerbread 构建中无法工作。

我不确定你是否能够绕过这个......
