[Xenomai-help] problem following 'xenomai quick build guide'

[Gregory Gosse]

[-- Attachment #1: Type: text/plain, Size: 1797 bytes --]

Hello all,

 

This is my first post . I'm from Toulouse France and absolute beginner in
Linux and Xenomai .

 

I try to install Xenomai on an Intel CORE i5 laptop.

 

I have installed Ubuntu 11.04 inside windows with wubi , and tried to follow
the 'Xenomai quick build guide'
http://www.xenomai.org/index.php/Xenomai_quick_build_quide 

 

Starting from scratch , to follow the quick build guide , I had to :

-          Log as root to paste files in /usr/tmp   ( 'sudo passwd root' to
define the root password in my initial guest session )

-          Install the 'patch' command with ' apt-get install patch' 

-          Install  libncure with 'apt-get install libncurses5-dev'

-          Get linux-2.6.25.tar.bz2  from www.kernell.org (
linux-2.6.25.11.tar.bz2 doesn't exist )

 

I have then get a x86_64 patch on adeos :

adeos-ipipe-2.6.23-x86_64-1.4-03.patch

and add it to /usr/src/xenomai-2.4.4/ksrc/arch/x86/patches/ 

 

I give the following informations in the 'prepare-kernel' script

> /usr/src/linux-2.6.25

> amd64

>
/usr/src/xenomai-2.4.4/ksrc/arch/x86/patches/adeos-ipipe-2.6.23-x86_64-1.4-0
3.patch

 

This step seems ok .

 

Then I enter 'menuconfig' and configure with the infos given on this
document "hard real time linux using xenomai on intel multi-core processors'
http://download.intel.com/design/intarch/papers/322386.pdf 

Save and exit

 

My problem is  in the step 'compile the kernel'

When I type 'Make' the compilation finishes with

 

gcc: erreur: elf_i386: Aucun fichier ou dossier de ce type               (in
English should give 'gcc : error :elf_i386 : no such file or directory' )

make[1]: *** [arch/x86/vdso/vdso32-int80.so.dbg] Erreur 1

make: *** [arch/x86/vdso] Erreur 2

 

What can I do to go further ?

 

Thanks for any help

Gregory

There is no point in starting with such outdated versions. Please
download the latest stable release of Xenomai (xenomai 2.6.0), and if
the quick build guide does not work, follow the not quick build guide
called "README.INSTALL" which ships with the sources.

Now i use more recent xenomai and kernel versions :

- xenomai 2.6.0   2011-11-05 ( latest )

- kernel 2.6.39 ( latest in 2.6 serie )

With the same patch :

- adeos-ipipe-2.6.23-x86_64-1.4-03.patch

 

I launch the command

scripts/prepare-kernel.sh --linux=/usr/src/linux-2.6.39 --adeos=/usr/src/xenomai-2.6.0/ksrc/arch/x86/patches/adeos-ipipe-2.6.23-x86_64-1.4-03.patch --arch=x86_64

 

And get

Unable to patch kernel 2.6.39 with adeos-ipipe-2.6.23-x86_64-1.4-03.patch

 

with many Hunk #xx FAILED at xx

- there is no support for 2.6.39/x86. Looking at ksrc/arch/x86/patches 
tells you so. Latest kernel release currently supported on this arch is 
2.6.38.8.

--arch=x86, not x86_64 which is for legacy patches when 32 and 64bit 
linux trees were not merged yet.

You need to unpack a vanilla linux 2.6.38.8 kernel tree, then

$ cd <linux-tree>
$ <xenomai-2.6.0>/scripts/prepare-kernel.sh --arch=x86

Nothing more.

Re: [Xenomai-help] problem following 'xenomai quick build guide'

[Gregory Gosse]

[-- Attachment #1: Type: text/plain, Size: 4011 bytes --]

Now I use:

- xenomai 2.6.0   2011-11-05

- kernel 2.6.38.8

- patch adeos-ipipe-2.6.38.8-x86-2.10-01.patch

 

The following command works well:

scripts/prepare-kernel.sh --linux=/usr/src/linux-2.6.38.8 --adeos=/usr/src/xenomai-2.6.0/ksrc/arch/x86/patches/adeos-ipipe-2.6.38.8-x86-2.10-01.patch --arch=x86

Then I enter the configuration menu with

Make menuconfig

 

I apply the changes suggested in 'hard real time linux using xenomai on intel Multi-Core processors'

Save and exit

 

When I try to compile the kernel with 'Make'  , the compilation finishes on:

CC      kernel/xenomai/nucleus/pod.o

Then do as the message says, disable "CONFIG_CC_STACKPROTECTOR" in the
kernel configuration. But are you sure you want to compile a 32 bits
kernel, not a 64 bits one?

Re: [Xenomai-help] problem following 'xenomai quick build guide'

[Gregory Gosse]

For the moment I use an Intel Core I5 as host and target .

Since I think I have to compile a  64bits kernel .

Do you know where is located CONFIG_CC_STACKPROTECTOR in the configuration menu ?

Then do as the message says, disable "CONFIG_CC_STACKPROTECTOR" in the kernel configuration. But are you sure you want to compile a 32 bits kernel, not a 64 bits one?

For x86_64 processors, you have the choice to compile a 32 bits or 64
bits kernels. If you have a 64 bits filesystem, you must compile a 64
bits kernel. If you have a 32 bits filesystem and want to compile a 64
bits kernel, you have to enable the 32 bits compatibility option.

Use ctrl-F to search if using "make xconfig" or "/" if using "make
menuconfig".

Thanks Gilles,

 

Well with “/” I found CONFIG_CC_STACKPROTECTOR that is in :

Processor type and features > Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)

 

I have disabled it

 

Then switching between different tutorials , I tried the following commands :

 

> make

ok ( take a moment )

>make modules

>make modules_install

>make install

>make bzImage

 

Here I get:

Root device is (7, 0)

Setup is 16220 bytes (padded to 16384 bytes).

System is 4238 kB

CRC 702aeac7

For x86_64 processors, you have the choice to compile a 32 bits or 64 bits kernels. If you have a 64 bits filesystem, you must compile a 64 bits kernel. If you have a 32 bits filesystem and want to compile a 64 bits kernel, you have to enable the 32 bits compatibility option.

Use ctrl-F to search if using "make xconfig" or "/" if using "make menuconfig".

rt-tests are testing real-time capabilities of the linux kernel, not of
xenomai.

If you are interested in a test which measures latency, run the
"latency" test.

The intel paper you cited contains a list of the tests xenomai contains.

Thanks Gilles,

 

Well with “/” I found CONFIG_CC_STACKPROTECTOR that is in :

Processor type and features > Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)

 

I have disabled it

 

Then switching between different tutorials , I tried the following commands :

ok ( take a moment )

>make modules

>make bzImage

 

Here I get:

Hi,

Is there just a way to avoid these 'undefined reference' errors ?

Before trying the examples, have you tried latency, switchtest,
switchbench, etc... or xeno-test?

No . What i wanted to do , starting from the examples, is write rapidly a simple program that perform periodically a task like writing on the serial port . And verify physically what happens.

Running the latency test under load an hour or two is recommended, to 
check if your platform has no issues.

Other than that, in order to compile the examples, you should read
this page:
http://www.xenomai.org/index.php/Examples

The following patch fixes some compilation issues, but even without 
this patch some of the examples do compile. The "unresolved references" 
you get are probably due to some missing arguments on make command line.
