Hello! I am beginner with Gentoo and absolute rookie about writing drivers, but I am trying to write one. I hope I have choose the right mailing list for my questions :-)
You should try the kernel-newbies mailing list, or the linux kernel mailing list.
I have encountered following error: I have a simple char driver. Everything is working like should be, I can compile functional driver, which after inserting into system appears in the sys file system. But when I add this lines in order to create my own attribute in directory of my module: #include <linux/sysfs.h> #include <linux/kobject.h> sysfs_create_file(&device->cdev.kobj,&pid_sfs); I can not insert module. Kernel says something like this: Error inserting module -1: unknown symbol sysfs_create_file
sysfs_create_file is only available to GPL modules. Is yours MODULE_LICENSE("GPL")?
