Dear All,

     I am new to Xenomai. But I am already using RTAI. I referred this page, http://www.xenomai.org/index.php/RTnet:Installation_%26_Testing and tested RTNet in RTAI. Its working fine. However now I would like to test the same RTNet in Xenomai. According to the wiki page, i could not able to start the rtnet successfully. When I tried to start the rtnet, I am getting the segmentation fault error. The errors clearly shows that the dependent modules are not loaded. 



Like RTAI dependent modules rtai_hal, rtai_lxrt, rtai_sem and rtai_rtdm, I did not loaded any modules in Xenomai. Even I never found any "modules" folder in my xenomai installation directory, /usr/xenomai/. I would like to know whether my xenomai is not properly installed or what are the other reasons rtnet is not started?. Kindly give me more about about from this wiki page, "If you have built the RTDM support of Xenomai into the kernel, nothing has to be done.". Do I no need to insert any modules?. Help me to resolve the above issues.

To install Xenomai, please follow the installation instructions. You
will find them in the README.INSTALL file in Xenomai sources
distribution, or online:
http://www.xenomai.org/documentation/xenomai-2.5/README.INSTALL

Dear Gilles,

     Thanks for the info. I justed followed the document, http://download.intel.com/design/intarch/papers/322386.pdf Coz I am also testing in the same ARCH. I followed the steps. Everything was fine without any issues and tested the xenomai-2.4.6 as they mentioned in the doc.

     But I have doubt that there is no modules created after it was installed successfully in /usr/xenomai/. I just like to know whether xenomai installation will create any "modules" folder in /usr/xenomai/ or not?. Like in RTAI mechanism(loading .ko modules one by one manually) is not necessary in xenomai?. Since I am new to xenomai, I found that I have zero .ko modules in my installation directory, /usr/xenomai. In other words I am not aware of Xenomai installed file structure. Do I need to load any modules to test RTNet in xenomai?.

You ask me a question.
I answer you: "read README.INSTALL".
You tell me: "I did not read README.INSTALL", then proceed to ask your
question again.
Are you kidding me?

Xenomai is integrated into the kernel tree and you have the option to
link Xenomai interfaces and drivers statically or dynamically (as
modules). So it depends on your kernel configuration. By default
everything is compiled statically! You should see Xenomai related output
when your system boots. Then, you just need to load the RTnet modules.

Yes. But I am sure, it was irrelevant to my query.

I never said, "I did not read README.INSTALL". I referred both of the files, the README.INSTALL and pdf file What I mentioned.    



>Are you kidding me?



Never. I guess you are kidding me. But whatever it may be, We are not sitting here for kidding each others. May be you misread my queries or my words were not clear. If you think I am kidding you, I would like to apologies for that. I dont like to waste your valuable time. So dont take my topics seriously in future and kindly ignore my threads.   



I got the expected info from wolfgang.



Thanks for your reply anyway.

And you are wrong. It answers exactly your question. It explains that
the build was split in two, a user-space part and a kernel-space part,
which is why, in particular, you will not get any module when compiling
the user-space part. It also explains that you have the possibility to
compile Xenomai support to be built-in the kernel, in which case you
will not get any Xenomai modules at all. How is that irrelevant to your
query.

Including me, most of the beginners are reading the README/INSTALL file first. But they are struggling at the begging coz of not clear about this documents. I referred both of the documentations. But I was not clear.



Now I got the clear idea about it. Thanks for the info.
