[DRBD-user] Could not determine uts_release

[Stef Morrell]

Hello,

I'm "Building against a kernel source tree" from the documentation at:

http://www.drbd.org/users-guide-emb/s-build-from-source.html

If you follow it through as

tar xvf linux.ver.bz
cd /path/to/linux.source
make mrproper
make .config (by whatever method)

cd /path/to/drbd
make clean
make KDIR=/path/to/linux.source

You will end up with

        Userland tools build was successful.
Could not determine uts_release
make: *** [module] Error 1

This is because version.h and utsrelease.h are not yet generated in the
kernel tree.

These files are generated at kernel compile time, or can be built by
issuing the command

make prepare

in the kernel source top level directory. 

make modules_prepare 

may be a better choice. 

Having said that, I'm struggling to find actual documentation for the
'prepare' and 'modules_prepare' targets for the kernel makefile, having
stumbled over them when trying different (documented) makefile targets
and getting some interesting error messages, so it might not be
something reliable. Building the complete kernel could be a better
recommendation.

In any event, the summary is: An additional step needs including in the
documentation to ensure utsrelease.h & version.h are generated in the
kernel source, as part of the 'Preparing the kernel source tree'

Hopefully this is useful :)
