Where is the version.h?

Hi,

According to LDD3, the linux/module.h automatically includes the linux/version, which define some macros to help test the kernel version. But I search the source tree, and can not find version.h in include/linux. Where can I find it?

Thanks!

It lives in include/generated/uapi/linux/version.h

If you've never built a kernel in your tree you won't find it though, because it's created from the Makefile. Look for version_h and filechk_version.h.

Accroding to LDD3, version.h is included with the path "linux/version.h", therefore I think the
"include/generated/uapi/linux/version.h"
might be symbolic linked to
"include/linux/version.h"
during compilation. Is this the case?

No, the build gets done with a -Iinclude/generated/uapi

So, I get it. Thanks for your reply!

It's auto-generated. You need to run at least a 'make prepare' in the
kernel tree (though you'll probably want to go ahead and actually build and
boot a kernel to develop against).
