如何修复这些不匹配

Question

使用的GCC：Linaro GCC 4.7/4.8/4.93/6.4/7.3，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。

我试着编译了一些源代码(例如官方LineageOS源代码(，每次我得到它：

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代码，所以我打赌我的电脑有问题，但我不知道如何调试。

我遇到过同样的问题！您可以先尝试将'CONFIG_NO_ERROR_ON_MISMATCH=y'添加到'make中，然后看看会发生什么，但它并没有解决我的问题。我不得不通过将">CONFIG_DEBUG_SECTION_ISMATCH=y"放入">make中来解释不匹配。

然后，这些不匹配会得到一个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谷歌上，希望有人能找到同样的路径。我的补丁是成功的，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！
