Error building vdk driver on linux

[achakraborty]

Hi,

I run make prepare and make scripts in the kenel source dirs, as documented in the README. But still I can't build the vdk driver for either 2.6.24.7 or 2.6.30-rc4 kernel. I get following errors for 2.6.24.7:

/usr/bin/make "V=0" -C /lib/modules/2.6.24.7/build SUBDIRS=/home/anirban/ptu32_001_lin_intel64/vdk/src modules

make: *** [default] Error 2

And I can't even go this far when I try to build it for 2.6.30-rc4. I get following errors right at the beginning:

checking for template makefile ... Makefile.in

checking for kernel headers ... /usr/src/linux-2.6.30-rc4/include

checking if C compiler is working ... yes

checking if C compiler supports anonymous structs and unions ... yes

checking architecture ... x86_64

checking kernel version ... 2.6.30-rc4

checking whether kernel modules can be built ... no

**

** ERROR: unable to build kernel module

**

** The kernel headers in /usr/src/linux-2.6.30-rc4

** are either inaccessible or not (properly) configured.

**

** The kernel headers must be accessible and configured prior

** to building the sampling driver (or any kernel module).

**

** Please see VDK doc/HOWTO-BUILD-VTUNE-DRIVER for help in

Any help will be highly appreacited.

Thanks,

Hi Anirban,

I suspect that PTU3.2 is too old - which can't support latest OSs and latest Intel processors.

Ihaven't seenin release notes thatlatest product can support kernel2.6.30-RC4, itmay not be tested! But it can support 2.6.27.5-117.fc10

Also make sure that you installed kernel source (consistent with running OS version)properly first. Then pay attention below in HOWTO-BUILD-VTUNE-DRIVER: (for example, you are working on not claimed supporting OS)

For 2.6-based kernels, the kernel sources can be configured as follows:

# boot into the kernel you wish to build driver for
# and make sure the kernel source tree is placed in
# /usr/src/linux-`uname -r`
#
cd /usr/src/linux-`uname -r`
vi Makefile # set EXTRAVERSION to a value corresponding to `uname -r`
make mrproper
cp /boot/config-`uname -r` .config
make oldconfig
make prepare
make scripts

Good luck!

Regards, Peter

Please remember that PTU is supported on the whatif.intel.com forums. This forum is for the VTune analyzer and it's features.
