Question

我在chaos calmer repo上，我有一个我需要使用的自定义内核配置。

内核配置文件位于

/opt/OpenWRT/target/linux/x86/config-3.18

我尝试过运行make kernel_oldconfig，但这并没有解决问题。

我尝试过运行make kernel_menuconfig，但也无法解决问题。

运行make时出现错误消息：

$ make
make[1] world
make[2] target/compile
make[3] -C target/linux compile
make -r world: build failed. Please re-run make with -j1 V=s to see what's going on
/opt/OpenWRT/include/toplevel.mk:181: recipe for target 'world' failed
make: *** [world] Error 1

解决此问题的唯一方法是使用make V=s -j1并浏览菜单互动。我不得不依赖一个处理器来编译整个buildroot。

仅当我使用自定义内核配置时才会出现这种情况，默认内核与make运行良好。

我复制（覆盖了）config-3.18目录中的target/linux/x86/文件。

内核适用于特定的32位x86架构（非通用）。

这是详细的输出：

有什么想法吗？

编辑：写这个问题时解决了......

Answer 1

我以为我之前已经将CONFIG_...行写入内核，但显然它们没有被保存，被覆盖或者其他一些问题。

我通过将其插入config-3.18文件的最后一行来解决错误：

CONFIG_X86_DECODER_SELFTEST=n

它可能没什么区别，但我也运行make kernel_menuconfig，加载然后保存配置文件，以防运行menuconfig做任何自动化。

Answer 2

还需要关注一个内核配置文件：

/opt/OpenWRT/target/linux/generic/config-3.18

适用于所有平台。

OpenWRT make失败，因为内核以交互方式请求配置选项
