android - 如何解决这些不匹配问题？

问题描述

使用的 GCC：Linaro-GCC 4.7/4.8/4.9.3/6.4/7.3 但版本似乎没有意义

操作系统：更新了 Linux Mint 19 和 4.17.2-ext73-57.2 内核。

我试图编译一些源代码（例如官方 LineageOS 源代码），每次我得到：

To build the kernel despite the mismatches, build with:
'make CONFIG_NO_ERROR_ON_MISMATCH=y'
(NOTE: This is not recommended)
/home/laptopfalcon/android_kernel_motorola_msm8226-oreo-turbo/scripts/Makefile.modpost:98: recipe for target 'vmlinux.o' failed
make[1]: *** [vmlinux.o] Error 1
Makefile:961: recipe for target 'vmlinux.o' failed
make: *** [vmlinux.o] Error 2

我应该怎么办？我试图搜索返回的变量，但没有找到任何提示。我无法正确编译任何源，所以我打赌我的电脑有问题，但我不知道如何调试它。

解决方案

我有同样的 问题！您可以先尝试将“ CONFIG_NO_ERROR_ON_MISMATCH=y ”添加到您的“ make ”中，然后看看会发生什么，但这并没有解决我的问题。我必须通过将“ CONFIG_DEBUG_SECTION_MISMATCH=y ”放入“ make ”来明确不匹配。

然后这些不匹配将得到更令人愉快的调试输出（错误日志），接下来你复制其中的一些并将其放在 Google 上，希望有人越过相同的路径。我的结果是成功的，因为我发现了这个补丁 https://github.com/LIMYOONAOS/android_kernel_leeco_x2-msm8996/commit/736f808bfefde74fdc8f6294c44f5c77a8e1d741

祝你好运！
