I have been asked quite a few times by individuals and companies about our project history, so FWIW, here it is: http://www.xenomai.org/index.php/Xenomai:History -- -- Philippe.
The roadmap to Xenomai 3 has been updated: http://www.xenomai.org/index.php/Xenomai:Roadmap -- -- Philippe.

If you are interested in writing a new skin, then you will find these links useful: http://rtai.dk/cgi-bin/gratiswiki.pl?How_To_Implement_A_New_Skin (BTW, I wonder if we should not copy this page in Xenomai wiki) http://www.xenomai.org/documentation/branches/v2.4.x/html/api/group__nucleus.html If you want the documentation of already existing skins, then you may have a look at: http://www.xenomai.org/documentation/branches/v2.4.x/html/api/group__native.html http://www.xenomai.org/documentation/branches/v2.4.x/html/api/group__posix.html http://www.xenomai.org/documentation/branches/v2.4.x/html/api/group__rtdm.html Other RTOS skins are not documented on the xenomai site, since they already have a documentation anyway. More generally, you should find a lot of information on Xenomai website: http://www.xenomai.org So, it would be really nice if you could read what is there. Bear in mind that our resources are limited. -- -- Gilles.
Hello, are there any news related to this topic? If ELDK 3.1.1 with kernel 2.4 works on your system there must be something wrong with our configuration...

Hi,
the simulator README tells you how to build it:

Please note that gcc 2.95 will not compile on x86_64, so, if you are running an x86_64, you should pass -m32 to gcc CFLAGS. -- -- Gilles.
Hi,
When the Xenomai is built, there is a segmentation fault. What are the possible scenarios that would cause this error? There is an “ld terminated with signal 11” error associated with this fault.
