Missing system.h

[VikCyc]

Greetings,

I think I've found a problem, but I don't have a bug report account, so I'm hoping someone here can help tell me if it is real and report it, or tell me it's not a problem...

Yesterday, I "yum update"d my Fedora 16 x86_64 system and picked up the new kernel version 3.4.4-4. I've also got kernel-headers and kernel-devel installed on my system.

Today, I attempted to install a HW driver that requires system.h, but make gave an error saying it couldn't be found. Doing a locate system.h shows that I do not have a system.h for kernel 3.4.4-4. It says I do have one for the previous two kernels, in /usr/src/kernels/3.3.x-x.fc86_64/arch/x86/include/asm/.

I uninstalled kernel-headers and kernel-devel and tried to re-install, but system.h is still missing. Is this a real problem with the 3.4.4-4 rpm, or is there something I don't understand about distributions? If a real problem, how can it be fixed? (I tried copying system.h from an old kernel src directory to the new one, but that caused additional compile errors).

By the way, I re-booted to the 3.3.7-1 kernel, and the driver seems to have installed correctly.

Regards,
VikCyc

Well, I don't have that file anywhere on my system either.

The current kernel from the update server is: 3.4.4-5.fc17.x86_64.

I did a quick google search and no one else is squawking about that file missing. Not sure what to tell you now.

You will need to edit the HW driver files to suit the 3.3 kernel changes

-            #include <asm/system.h>
+	    #include <linux/version.h>
+#if LINUX_VERSION_CODE > KERNEL_VERSION(3, 3, 0)
+	    #include <asm/switch_to.h>
+#else
+	    #include <asm/system.h>
+#endif

Okay, so where is the system.h file you referred to? Nowhere under the /usr/src/kernels/3.4.4-5.fc17.x86_64 is there a folder named asm/ with a file named system.h located in it.

Maybe I a missing something here.

The output posted is patch fomat, the lines prefixed with - are removed and the + lines are added.


asm/switch_to.h is the replacement for asm/system.h in 3.3 + kernels

Cool, thank you Yellowman, that is nice to know. I am not a programmer, only ever rebuilt one or two kernels and just followed the instructions (with fingers crossed) and it all worked out.

From what I see above it is a conditional statement that says if the kernel version is greater than 3.3.0 then we will use a file named switch_to.h otherwise it will have a file named system.h, is that correct?

Yes.........

Short story - your driver is out-of-date and may well require more changes to be made to work on a modern kernel.

Thank you Yellowman very much for the info - Very helpful!

I consider this one "solved".
