[lustre-discuss] Compiling from sources with Debian 8

The 2.3.64 version means you are using the in-kernel Lustre client (confirmed by the waning messages about "staging"), and not the 2.7.x version from the Lustre master branch.
It looks like Ubuntu is building the in-kernel client, and your modules are not being loaded.

We run lustre 2.6/2.7 on our Centos 6.6 (servers) and 7 (clients) cluster. We have a few webservers running Debian that need to access the storage. I followed the procedure given by Thomas Stibor about Ubuntu 14 last year.
I could successfully compile the binaries and modules after some digging. He also left an already compiled lustre 2.7.63 and modules for kernel 3.16.0-4 online.
If I install his binaries, it works well. If I install the one generated by the procedure, the modules don't load and a weird thing happen. Running dmesg warns me about one surprising thing :

I pulled the master git branch, and coul obtain
linux-patch-lustre_18.104.22.168-16-g8524994_all.deb lustre-client-modules-3.16.7-ckt11-lustre-my-build_22.214.171.124-16-g8524994_amd64.deb lustre-tests_126.96.36.199-16-g8524994_amd64.deb

I just don't get it. Why the shown version of the module is 2.3 ?
I tried to compile from the 2.7 branch but the 2.7.0 version doesn't compile with kernel 3.16, as suggested in LU-7042
I probably miss something. Sorry I'm not familiar with compilers (usually the ./configure && make && make install works or warns you about missing dependencies and i don't go farther).
PS : Here is the procedure followed to compile
apt-get install linux-headers-3.16.0-4-amd64 libtool automake linux-source-3.16
git clone git://git.whamcloud.com/fs/lustre-release.git
tar xf linux-source-3.16.tar.xz
vi debian/rules (edit so it doesn't stop with autogen because it doesn't find the kernel sources)
(modify --with-linux= option with current path --with-linux=/usr/src/linux-3.16 in kdist_config section)
aptitude install module-assistant libreadline-dev debhelper dpatch libsnmp-dev quilt devscripts
(modify the dependency for unsatisfied linux-headers called linux-headers-something in jessie)
export DEBFULLNAME="Niemand Nobody"
export EMAIL="npcomplete at example.com<http://example.com>"
# Extract lustre version, replace "_" by "." and remove leading letter "v".
LUSTRE_VERSION=$(echo `git describe` | sed -e "s/_/\./g" | cut -c2-)
# Add entry into debian/changelog such that packages have proper version names.
dch --newversion $LUSTRE_VERSION --distribution unstable --nomultimaint -t "Build from official master upstream."
# Build debian packages.
# Build modules.
#make-kpkg modules_image --append-to-version -lustre-my-build --revision `date +"%Y%m%d"`
Then i got stuck on "checking for external module build target" for a while, fixed by running "make scripts" in the kernel source folder
It finally compiled !
