[uml-user] Problems building UML from 2.6.16: cannot set up thread-local storage

John Zavgren Fri, 16 Jun 2006 14:51:58 -0700

Greetings:

I'm trying to build UML from the stable release of the 2.6.16 kernel sources by doing the minimal number of steps... All I'm trying to do is prove that I can build a UML kernel from source code, that will mount a root file system. I'm taking my instructions directly from the new UML book, Chaper 11.

FYI: The root file system I'm using works fine with a precompiled UML kernel that I downloaded from the net that was built from the 2.6.17 sources:

-------------- motd and login information

Fedora Core release 5 (Bordeaux)
Kernel 2.6.17-rc1 on an i686

localhost login: root
Last login: Fri Jun 16 16:52:33 on tty0
[EMAIL PROTECTED] ~]# uname -a
Linux localhost 2.6.17-rc1 #89 Mon Apr 3 15:47:47 EDT 2006 i686 i686 i386 GNU/Linux
[EMAIL PROTECTED] ~]#

--------------------------------------------------

(I've used the file /proc/config.gz from this working example to configure my 2.6.16 kernel code... but that doesn't work.)

First, I configure the kernel code for UML:

make mrproper

make mrproper ARCH=um

make defconfig ARCH=um

make ARC=um

After "linux" is built, I use the command: ./linux

The root file system gets mounted, but I get an error about thread-local storage

VFS: Mounted root (ext3 filesystem) readonly.
cannot set up thread-local storage: set_thread_area failed when setting up thread-local storage

Kernel panic - not syncing: Attempted to kill init!

Then I do this:

./linux init=/bin/sh LD_ASSUME_KERNEL=2.4.1

...

VFS: Mounted root (ext3 filesystem) readonly.
/bin/sh: error while loading shared libraries: libdl.so.2: cannot open shared object file: No such file or directory

I read the instructions in http://user-mode-linux.sourceforge.net/faq.html

I followed the directions in cannot set up thread-local storage.

The kernel still dies after it mounts my root file system.

Any ideas?

Thanks!

I've tried building the kernel with configuration files from http://www.stearns.org/uml/. This doesn't help either.
