"FATAL: Module not found error" using modprobe
提问by Ravi Gupta
I have a problem with modprobecommand... I compiled the hello world module and loaded it with insmod, it works fine and when I do lsmod, I can see it in the output list. But when I insert this module using modprobeI am getting a FATAL error:
我的modprobe命令有问题...我编译了 hello world 模块并加载了它insmod，它工作正常，当我这样做时lsmod，我可以在输出列表中看到它。但是当我使用插入这个模块时，我modprobe收到了一个致命错误：
root@okapi:/home/ravi# modprobe ./hello.ko
FATAL: Module ./hello.ko not found.
root@okapi:/home/ravi#
Here is the module code:
下面是模块代码：
#include <linux/init.h>
#include <linux/module.h>
MODULE_LICENSE("Dual BSD/GPL");
static int hello_init(void)
{
printk(KERN_ALERT "Hello, world\n");
return 0;
}
static void hello_exit(void)
{
printk(KERN_ALERT "Goodbye, cruel world\n");
}
module_init(hello_init);
module_exit(hello_exit);
and Makefile
和生成文件
obj-m += hello.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
采纳答案by che
The reason is that modprobelooks into /lib/modules/$(uname -r)for the modules and therefore won't work with local file path. That's one of differences between modprobeand insmod.
原因是modprobe查找/lib/modules/$(uname -r)模块，因此不适用于本地文件路径。这之间的差异的一个modprobe和insmod。

Try insmodinstead of modprobe. Modprobe
looks in the module directory /lib/modules/uname -rfor all the modules and other
files
尝试insmod代替 modprobe。Modprobe 在模块目录 /lib/modules/ 中uname -r查找所有模块和其他文件

The best thing is to actually use the kernel makefile to install the module:
最好的办法是实际使用内核 makefile 来安装模块：
Here is are snippets to add to your Makefile
这是要添加到 Makefile 的片段
around the top add:
在顶部周围添加：
PWD=$(shell pwd)
VER=$(shell uname -r)
KERNEL_BUILD=/lib/modules/$(VER)/build
# Later if you want to package the module binary you can provide an INSTALL_ROOT
# INSTALL_ROOT=/tmp/install-root
around the end add:
在最后添加：
install:
$(MAKE) -C $(KERNEL_BUILD) M=$(PWD) \
INSTALL_MOD_PATH=$(INSTALL_ROOT) modules_install
and then you can issue
然后你可以发出
sudo make install
this will put it either in /lib/modules/$(uname -r)/extra/
这将把它放在 /lib/modules/$(uname -r)/extra/
or /lib/modules/$(uname -r)/misc/
或 /lib/modules/$(uname -r)/misc/
and run depmod appropriately
并适当地运行 depmod
回答by Gouse
Insert this in your Makefile
$(MAKE) -C $(KDIR) M=$(PWD) modules_install
it will install the module in the directory /lib/modules/<var>/extra/
After make , insert module with modprobe module_name (without .ko extension)
OR
或者
After your normal make, you copy module module_name.ko into directory /lib/modules/<var>/extra/
then do modprobe module_name (without .ko extension)
然后做 modprobe module_name （没有 .ko 扩展名）

Ensure that your network is brought down before loading module:
在加载模块之前确保您的网络已关闭：
sudo stop networking

i think there should be entry of your your_module.ko in /lib/modules/uname -r/modules.dep and in /lib/modules/uname -r/modules.dep.bin for "modprobe your_module" command to work
我认为应该在 /lib/modules/ uname -r/modules.dep 和 /lib/modules/ uname -r/modules.dep.bin 中输入 your_module.ko 以使“modprobe your_module”命令起作用
