Re: [Linux-gpib-general] RHEL 9 build failing

[Cris C. <clc...@gm...>]

Solved.
RHEL 9's 5.14 kernel must be showing up as greater than 6.4
Changed device.h from:

#if LINUX_VERSION_CODE < KERNEL_VERSION(6,4,0)

#define CLASS_CREATE(owner, name) \

        class_create(owner, name)

#else

#define CLASS_CREATE(owner, name) \

        class_create(name)

#endif


To:

#define CLASS_CREATE(owner, name) \

        class_create(name)
