Question

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

OS：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LineageOS的官方源代码），并且每次我得到这些代码时：

WARNING: vmlinux.o(.data+0x10f40): Section mismatch in reference from the 
variable gdsc_driver to the (unknown reference) .init.data:(unknown)

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，因此我敢打赌我的PC出了点问题，但是我不知道如何调试它。

我遇到了相同问题！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，但这并不能解决我的问题。我必须通过将' CONFIG_DEBUG_SECTION_MISMATCH = y '放入' make '中来明确显示不匹配项。

然后，这些不匹配项将获得更令人满意的调试输出（错误日志），接下来，您将其中的一些复制并放到Google上，以希望有人越过相同的道路。我发现这个补丁 https://github.com/LIMYOONAOS/android_kernel_leeco_x2-msm8996/commit/736f808bfefde74fdc8f6294c44f5c77a8e1d741

证明我的成功

祝你好运！

如何解决这些不匹配问题？
