After I figuerd out my ubuntu 12.10 amd64 with 3.5.X Kernel does not fill some queuing, and they've fixed that in kernel 3.8.x, I upgraded the kernel of my Ubuntu to v3.10-saucy with installing deb files from the mainline Kernel archive and things went well.
uname -r
3.10.0-031000-generic
And the
sudo apt-get install linux-image-3.10.0-031000-generic
says me things already installed.
But after I come to compile my C code with gcc, it still claims that the piece of code that suppose to work on > 3.8.x, is undeclared!
The problem is the new installed kernel header is in
/usr/src/linux-headers-3.10.0-031000-generic/include/
but /usr/include still holds the old headers. Gcc still reads from /usr/include for header files.
Then, I came with this:
gcc --verbose -I /usr/src/linux-headers-3.10.0-031000-generic/include/ -o test.out test.c

Then, I did:
gcc -nostdinc -I /usr/src/linux-headers-3.10.0-031000-generic/include/
to don't let gcc to access /usr/include. But it claims again some include files like <net/if.h> not found and by removing that header files, it gives some other not found crap inside the found include files either.
If <net/if.h> is related to c library, it could be right, because make the gcc not to read other include folders.
But it reports some not found inside
<linux/if_tun.h>

So how do I suppose to get over this?
