[uml-devel] Problems compiling any 2.6.x UML

[uml-devel] Problems compiling any 2.6.x UML

[Dominik Jürgens]

I have a problem with compiling user-mode-linux on my debian sarge
system. Some importent package versions:
 
Hostkernel 2.6.8.1
gcc (GCC) 3.3.4 (Debian 1:3.3.4-6sarge1)
GNU Make 3.80
GNU binutils version 2.14.90.0.7 20031029 Debian GNU/Linux

Problem: When I try to compile any 2.6.x UML-Kernel I get following
message:

make ARCH=um linux \n
...
<--zip-->
  LD      init/built-in.o
  LD      .tmp_vmlinux1

</--zip-->

I googled for it a longer time and found nothing. 

Thanks for helping me :-)

Re: [uml-devel] Problems compiling any 2.6.x UML

[Ralph Paßgang]

Hi,

I have builded debian packages for 2.6 umls, or better I made the original 
debian sourcepackage include a 2.6 kernel and compile cleanly.

You can get the source-package at:
deb http://packages.debianbase.de/sources/uml-exp/ ./

and the binaries for sarge at:
deb http://packages.debianbase.de/sarge/i386/uml-exp/ ./

The last version available there is 2.6.8, but I would suggest that you test 
the 2.6.6 package, because I know that this version works without any problem 
on more than just my machine. The 2.6.7 should be fine, too.

I have problems myself with the 2.6.8 package, but I have to take a closer 
look at this, because I don't know if its a debian packaging problem or 
something like this or actually a uml bug. But any of these source packages 
compiles cleanly without any problem.

Ah, before I forget it: with skas patch in the host kernel the umls are 
running very smoothly... Without skas patch the umls sometimes doesn't start 
(diffrent kernel panics).  I don't know why, but I am a bit confussed because 
the uml kernel doesn't always hang at the same point... Maybe there is 
something broken in the uml or in the debian system...

Hope this helps a bit...

If /bin/sh is not bash, this is the problem.

Re: [uml-devel] Problems compiling any 2.6.x UML

[Dominik Jürgens]

Thank you very very much, that really fixed the problem!

But why does anyone use the /bin/sh in any script, when he wants to use
the bash? That is in my opinion a very bad fault!!

My /bin/sh was linked to the /bin/dash, not because I linked it, but
anything else! It does not seem to be very failure tolerant to suppose
that /bin/sh is the bash...

/bin/sh is by UNIX standard a "UNIX compatible shell". It does not need to 
be bash, but it needs to implement the UNIX standard shell syntax.

So any shell script using the UNIX shell syntax should be using /bin/sh

Any shell script explicitly written for bash only shold be using /bin/bash

Assuming /bin/sh understands bash specific extensions to the UNIX shell 
syntax is wrong.

Henrik

I thought that any script in the build process uses such an extention,
so I wanted to report this. If not, I agree to you!

1) Someone else got a similar problem, because he used a Debian, too, and he 
had /bin/sh -> /bin/dash. Why and when does Debian do this?

2) Well, I'm attaching the patch to fix this.

Debian doesn't do this, but Debian users are permitted to do so if they
desire, in order to have a more lightweight /bin/sh.  The only requirement
is that /bin/sh be POSIX compliant, so scripts which specify #!/bin/sh must
be written with only POSIX syntax.

Someone has already answered this, but here is a more detailed answer:

When you install the dash package it will ask you if you want to use 
this as your default shell. This should be OK, since dash is posix 
compliant, and if you ask for /bin/sh you should only expect posix 
compliance. Under debian, any package that specifies /bin/sh and then 
uses bash extensions will normally get a level 3 bug raised, which is a 
violation of packaging policy. I.e. Only use /bin/sh if you want a 
posix shell, otherwise use /bin/bash.

As to when, dash is the only package that I know of that will do this 
for you, and then only if you ask it to. Why? Dash is faster than bash, 
and could save up to a second of boot time! ;-) Seriously, some people 
use it to ensure package compliance, some people do it because it seems 
right. I do it because it has a very low overhead, and it helps me to 
ensure that my scripts are cross platform compatible.

Much appreciated :-)

Cheers,
Paul
