System.map: No such file or directory

During a make, I get this error:

Code:

mahmood@lcoalhost:sample$ sudo make install
test -d /lib/modules/2.6.32-25-generic/kernel/drivers/hwmon || mkdir /lib/modules/2.6.32-25-generic/kernel/drivers/hwmon
cp k10temp.ko /lib/modules/2.6.32-25-generic/kernel/drivers/hwmon
depmod -a -F /lib/modules/2.6.32-25-generic/build/System.map 2.6.32-25-generic
FATAL: Could not open '/lib/modules/2.6.32-25-generic/build/System.map': No such file or directory
make: *** [modules_install] Error 1

I have install linux headers

Code:

mahmood@localhost:k10temp$ sudo apt-get install linux-headers-2.6.32-25-generic

So what is the problem?

The problem is you are missing a file in the path it expects to find it:

Quote:

FATAL: Could not open '/lib/modules/2.6.32-25-generic/build/System.map

What happens if you type?:

Code:

ls -l /lib/modules/2.6.32-25-generic/build/System.map

If it says "not found" it means you don't have that file in that directory. Either you need to find where System.map or you need to install a separate package that includes System.map. If the file DOES exist on your system but is in a another directory you can create a symbolic link in /lib/modules/2.6.32-25-generic/build to where it really exists OR you could modify the makefile to point to the correct path.

There is no System.map in the required folder or anywhere else:

Code:

mahmood@localhost:k10temp$ ls -l /lib/modules/2.6.32-25-generic/build/System.map
ls: cannot access /lib/modules/2.6.32-25-generic/build/System.map: No such file or directory
mahmood@localhost:k10temp$ sudo find / -name "System.map"
mahmood@localhost:k10temp$

Personally I have no idea... I think it is a file that must come with linux headers. I installed linux headers but there is no such file

The Wikipedia article at http://en.wikipedia.org/wiki/System.map
says that System.map is generated at build time of the kernel.

This says in part:

Quote:

After building the Linux kernel, System.map is located in the root of the source directory. However, some further software installation steps expect to locate the file elsewhere:

* as /boot/System.map-$(uname -r)
* Building SVGALib expects to find /lib/modules/$(uname -r)/build/System.map

Do an "ls -l /boot/System.map*" and see if you have any files appended with the System.map. If so do a symbolic link of that to the location your make is looking for it in. e.g.
"ln -s /boot/System.map-2.6.32-25-generic /lib/modules/2.6.32-25-generic/build/System.map"

Also based on above it may be you need to install the kernel source package to be able to do your make. You don't mention what it is you're trying to make.

Yes thanks you. "System.map" was there. I am trying to make the k10temp module which is a driver from lm-sensors for AMD k10 CPUs
