我有一个正在尝试交叉编译的第 3 方设备驱动程序。当我构建驱动程序时，一切都很顺利，但我没有看到任何 driver.ko 文件，但是 driver.o 文件生成正常，并且在构建过程中我没有看到任何错误。我也尝试使用选项 V=1 并且看到以下错误
echo;
echo " ERROR: Kernel configuration is invalid.";
echo " include/generated/autoconf.h or include/config/auto.conf are missing.";
echo " Run 'make oldconfig && make prepare' on kernel src to fix it.";
echo;
但是我的内核配置是正确的，我已经尝试了一个简单的 hello world 模块，在这种情况下，我可以构建我的模块，但仍然看到这个错误消息。我还可以在内核源代码中看到文件 include/generated/autoconf.h 和 include/config/auto.conf 。仍然为什么我无法构建我的驱动程序模块。
这是构建的输出。

正如您在上面看到的 ar6000.o 正确构建而没有任何错误，但为什么没有构建 ar6000.ko 否则它应该报告“MODPOST 1 模块”。由于在完整构建过程结束时未构建 ar6000.ko，因此我也收到以下错误
cp: cannot stat `/home/farshad/Work/CSP/boards/imx6q/ar6k3/ar6003_3.1_RC_Linux_release_[posted_2011_8_19_olca3.1RC_553/imx6build/host/os/linux/ar6000.ko': No such file or directory
2404 make[1]: *** [install] Error 1
这是显而易见的。我的问题是为什么我一开始就没有得到 ar6000.ko。在谷歌上搜索有人也遇到了这个问题，并提到用 sudo 运行 make 解决了它，但它没有给我带来运气！
我在徘徊我的内核配置是否有任何问题（即驱动程序正在寻找一些我尚未在我的内核中启用的配置设置，但在这种情况下它应该给编译器错误寻找所需的#define），另一点可能是驱动程序构建系统存在问题，我正在努力解决这个问题。我的交叉编译环境很好，因为我在为我的（Ubuntu x86）机器构建相同的驱动程序时看到了完全相同的问题！
有什么想法吗。问候， Farrukh Arshad
更新 #1 它是一个第 3 方驱动程序包，它还与驱动程序模块一起构建其他实用程序。这是驱动模块构建过程的输出
