I don’t remember when it happened, but sometime in the past four years,
the Makefiles for the kernel named Linux changed. I can’t remember
exactly, but I do recall sometime “recently” that the
kernel build output stopped looking like what I remember from 1991,
and started looking like this:

CC arch/i386/kernel/semaphore.o CC arch/i386/kernel/signal.o

This is a heck of a lot easier to read, but there was something cool
about having make display the whole gcc
command lines, like this:

gcc -m32 -Wp,-MD,arch/i386/kernel/.semaphore.o.d -nostdinc -isystem /usr/lib/gcc/i486-linux-gnu/4.0.3/include -D__KERNEL__ -Iinclude -include include/linux/autoconf.h -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -ffreestanding -Os -fomit-frame-pointer -pipe -msoft-float -mpreferred-stack-boundary=2 -march=i686 -mtune=pentium4 -Iinclude/asm-i386/mach-default -Wdeclaration-after-statement -Wno-pointer-sign -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(semaphore)" -D"KBUILD_MODNAME=KBUILD_STR(semaphore)" -c -o arch/i386/kernel/semaphore.o arch/i386/kernel/semaphore.c gcc -m32 -Wp,-MD,arch/i386/kernel/.signal.o.d -nostdinc -isystem /usr/lib/gcc/i486-linux-gnu/4.0.3/include -D__KERNEL__ -Iinclude -include include/linux/autoconf.h -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -ffreestanding -Os -fomit-frame-pointer -pipe -msoft-float -mpreferred-stack-boundary=2 -march=i686 -mtune=pentium4 -Iinclude/asm-i386/mach-default -Wdeclaration-after-statement -Wno-pointer-sign -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(signal)" -D"KBUILD_MODNAME=KBUILD_STR(signal)" -c -o arch/i386/kernel/signal.o arch/i386/kernel/signal.c

I never gave it much thought, since the new form was easier to read. I
figured that those folks who still eat kernel code for breakfast knew
about this change well ahead of time. Of course, they were the only
ones who needed to see the verbose output of the gcc
command lines. I could live with seeing the simpler CC
lines for my purposes, until today.

I was compiling kernel code and for the first time since this change in
the Makefiles, I was using a non-default gcc to build
Linux. I wanted to double-check that I’d given the right options to
make throughout the process. I therefore found myself
looking for a way to see the full output again (and for the first
time). It was easy enough to figure out: giving the variable setting
V=1 to make gives you the verbose version.
For you Debian folks like me, we’re using make-kpkg, so
the line we need looks like: MAKEFLAGS="V=1" make-kpkg kernel_image.

It’s nice sometimes to pretend I’m compiling 0.99pl12 again and not
2.6.20.7. 🙂 No matter which options you give make, it is
still a whole lot easier to bootstrap Linux these days.

Es ist vollbracht! Today, at 10:54 am — 66 min before deadline — I
handed in my diploma thesis ^[1]. In a few weeks time you may call me
Diplom-Informatiker… Herr Diplom-Informatiker.

That’s all.

Footnotes:

[1] Thesis title is Diensteverwaltung in Ad-Hoc-Netzwerken
(which roughly translates to Service Discovery in Ad-Hoc Networks).
Basically, the thesis is about “Mesh-DNS”, a protocol akin to Multicast DNS (mDNS), which scales
better, fixes a few things and takes Mesh network architectures into account.
It is intended to be integrated into Avahi and
to be used as service discovery protocol in OLPC. It is compatible with DNS-SD, but replaces mDNS. Due to that all
existing software linking against Avahi can make use of it without any major
changes. It adds a zone .mesh which is organized by Mesh-DNS side-by-side to the mDNS-maintained zone .local. You will be able to enable support for Mesh-DNS at Avahi
compile time. Most likely most distros won’t enable it in their default builds,
although it offers quite a few features even outside OLPC, such as
automatic, idiot-proof router transparency.

What’s going on with LinuxTag?

Does anybody know what’s going on with LinuxTag? I submitted a presentation
proposal a few months ago. I haven’t yet received an email whether my talk has been
accepted or not. According to their
website notification emails should have been sent out on march 13th. Which
is nearly a month ago now. When I login to the “virtual conference
center” I see that my paper is still “In Review”. They didn’t respond to my emails (twice).

Does anyone have an idea what is going on?
