编译Linux内核模块时报：WARNING: Symbol version dump "Module.symvers" is missing.

问题描述

我在OpenSUSE Linux中运行make构建一个自定义驱动程序，用于与一些外部设备进行通讯，Makefile在其他Linux系统中make都正常，但就在Open SUSE中编译报警告：WARNING: Symbol version dump “Module.symvers” is missing. 和错误：/bin/sh: scripts/mod/modpost: No such file or directory，详细如下：

~/p/func > sudo make -k
make -C /lib/modules/`uname -r`/build M=/home/name/programs/func/driver
make[1]: Entering directory '/usr/src/linux-5.14.21-150400.22-obj/x86_64/default'
WARNING: Symbol version dump "Module.symvers" is missing.
         Modules may not have dependencies or modversions.
         You may get many unresolved symbol warnings.

解决办法

在内核目录/usr/src/linux-5.14.21-150400.22-obj/x86_64/default中执行以下命令：

sudo make scripts

然后执行安装：

sudo zypper install kernel-default-devel

再编译就能够正常生成.ko模块了。
