Hey - what's up with Ubuntu

I recently upgraded my Ubuntu install from 6.x to 8.04. I'm trying to setup
the machine the way it was before and I need to install some software that
needs to compile it's own kernel modules. No problem since I have gcc
installed - or so I think. Because when the installer attempts to build the
kernel module it gives this error:

- 'Your kernel was built with "gcc" version "4.1.3", while you are
trying to use "/usr/bin/gcc" version "4.2.3". This configuration is not
supported.'

So what's up with this? Isn't a bug/error for Ubuntu to ship 8.04 with a
different compiler than what the kernel was built with? I never explicitly
upgraded my gcc version. After the initial install I downloaded the 158
required updates that update manager told me that I needed. But what's the
point of Ubuntu installing a version of the compiler that isn't compatible
with the compiler the used to build the kernel?

After takin' a swig o' grog, Ezekiel belched out
this bit o' wisdom:

That's to be expected, really. It happens in Debian, too.

But you may be able to workaround it. I had to do this at work,
as I update my system quite frequently, while the other developers working
on Linux apparently do not. I run the build from the command line. Before
starting it, though:

$ export CC="gcc-4.1"
$ export CXX="g++-4.1"

The make process then uses this older compiler.

On the desktop system, I have versions 3.3, 3.4, 4.1, 4.2, and 4.3
installed.

Ooops. Accidentally sent the old post before I was ready. This is a new
Ubuntu 8.04 install and I don't recall running into this before.

Question for you - If I do this will my installed gcc (4.2.x)
automatically use the 4.1.x "compatibility mode" or do I also need to
install the older compiler as well?

Since I need to manually launch the install/build script from the CLI
exporting these env-vars isn't a problem.

No previous installs here. Just what came with Ubuntu. And now I noticed
there's another unrelated issue. The 'Update manager' keeps notifying me
that I have updates to install. They all installed but these 6 keep
failing with the same error (Below). Have you run into this? What's up...
did these updates get pulled from the site for some reason?

I think the latter. I have 5 gcc executables installed, and a plain gcc
soft link to the latest version.

I installed the 3.x version explicitly, IIRC. You can do the same in
synaptic, I'd bet.

Cache problem? Beats the hell out of me. (And don't you tell that sounds
like a good idea!!!)

Most apps, and I'm guessing gcc usually create a link from the generic (ie
gcc, db2, etc) to the latest version. If you upgrade then the old version is
still there but you need to call it explicitly. Right now for example
/usr/bin/gcc is a link to gcc-4.2.

I'll have to try this all later. I'm in the middle of a huge backup right
now (remember how I was earlier talking about ESXi and virtualization) so I
need to let that finish before I retry building the kernel modules. (It's a
network driver and part of the build is to restart the network which would
disconnect the backup client.)

See if it goes away in a couple days

Just got it "working" but this is weird. From the GUI Synaptic Package
manager this fails every time. But I just went to the CLI and typed in:

sudo apt-get update

sudo apt-get upgrade

And it worked the first time. Looking at the output there's:

Get:5 [url]http://us.archive.ubuntu.com[/url] hardy-updates/main libgvfscommon0
0.2.5-0ubuntu3 [33.0kB]

Get:6 [url]http://us.archive.ubuntu.com[/url] hardy-updates/main gvfs-backends
0.2.5-0ubuntu3 [684kB]

So there's a difference in the URLs. The GUI is trying to fetch from
..../ubuntu/pool/main... and apt-get got it from .../hardy-updates/main/...



DAMN - Another problem. I can't post this from pan. This is a new install
and I was able to make a few posts. And then some failed. And then some
worked again. And now this one is failing with a error 441 - No valid
newsgroups. So I need to remote desktop into my Windows box to send this.

ERRR!!!!! I set the RDP screen resolution a bit too high for this laptop so
I can't see the entire bottom of the screen. But there's *no* scrollbars on
the terminal services. You got to have scrollbars!!!

I like aptitude (the console "GUI").
