Question

我在为 lineageos 项目构建 ROM 时遇到以下异常，需要一些帮助来诊断和解决问题：

Answer 1

问题是我缺少内核 uapi 包含的定义。一旦我添加了这些定义，我就能够通过构建问题。我从 Lenovo 导入了一个内核，它不包含 xiami 内核的定义。

https://github.com/redmidevs/android_kernel_xiaomi_msm8917/commit/b33b025abaf5213ccfe1b5e17f75785163eb696a

#define SND_AUDIOCODEC_DSD                   ((__u32) 0x00000021)
#define SND_AUDIOCODEC_MAX                   SND_AUDIOCODEC_DSD

和
