OpenWRT make 失败，因为内核以交互方式请求配置选项

Question

我在 chaos calmer 存储库中，我有一个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

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

我试过运行 make kernel_menuconfig 也未能解决问题。

运行时的错误消息：

$ 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 并完成菜单交互。我讨厌不得不依赖一个处理器来编译整个 buildroot。

这仅在我使用自定义内核配置时发生，默认内核在 make 下运行良好。

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

内核用于特定的 32 位 x86 架构（非通用）。

这是详细输出：

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，它们被覆盖了，或者其他一些问题。

我通过将此插入 config-3.18 文件的最后一行解决了错误：

CONFIG_X86_DECODER_SELFTEST=n

这可能没什么区别，但我也运行 make kernel_menuconfig，加载并保存了配置文件，以防万一运行 menuconfig 做了任何自动操作。

您还需要关心一个内核配置文件：

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

这适用于所有平台。

OpenWRT make is failing because kernel is asking for config options interactively
