Hello,
I try to install Xenomai on Ubunut Hardy 8.04. Versions used are:
- xenomai-2.4.6.1
- linux-kernel 2-6.24.6
- adeos patch: adeos-ipipe-2.6.24-x86-2.0-07.patch
I tried many .config files but it is always the same problem with Xeno-test. It seems that there is a problem with the "generate load" part of the script.
Attached, are two files. One is xeno-test without modifying it. The other is xeno-test results but with the "generate load'" part removed.
Latency (in user space and kernel) seem to be great. Around 7 us in user-space and 4 us in kernel for worst case.
Thanks in advance for your help,
Mathieu

Unfortunately, latencies obtained without loading the system are
meaningless. So, generating a load is mandatory. I am afraid you will
have to debug why the load generator does not work for you.

The thing is that as I had to compile many times my kernel in order to try many .config, I had time to try to run ./latency when compilation is made. And there is no problem with latencies for example.
What does make exactly the load generator ? How can I try to debug it ?
Mathieu

xeno-test is a script, so, debug it the way you would debug any script.
bash -x is your friend.
Also, since you seem to be running a localized Linux, you could try
export LANG=C before running the script.

Come on ! Debugging a script is not that hard.

You can find what is busybox with google or wikipedia. And in any case,
you can look in the script to see how this withBusybox variable is set.
Please use the mailing list.

I know this thread is a year old now, but there was never a solution
posted. I ran into the same problem a few months ago, solved it, ran
into it again yesterday, and forgot how I solved it before.
So, just to document the solution for posterity's sake (or for anyone
Googling for a solution):
The xeno-test script fails with "something died a <xxxx>" when it is run
under the dash shell for me. The xeno-test script specifies "/bin/sh" as
a shell, and under my distro (Ubuntu 9.10 now), /bin/sh => dash, not
bash. The dash shell is designed to be a fast, efficient,
non-interactive shell mainly for running scripts, and therefore has a
limited feature set when compared with bash.
It seems dash is not able to handle whatever xeno-test is asking it to
do at that moment. But the xeno-test script works fine (for me) when run
with "bash xeno-test".
There. Now I just need to sit back and let all the little web-crawling
robots index the heck out of this email. Soon, this solution will show
up in a half-dozen "mailing list archive" sites, and I'll never have to
re-solve it again! :-)
Sincerely,

That is not a good solution. bash is not available on embedded platform.
The real platform is to fix the script to run with dash. And it is far
from impossible. I mean come on, xeno-test runs with busybox' ash, I do
not see why it would not run with dash.
