[Xenomai-help] xenomai 2.6.0:Linkage Error.

Hello;

   I was using Xenomai 2.4.8 .  My applications were running and I had no
linkage or run time errors.

   Due to some necessities ,xenomai 2.6.0. But I can even not  run
xenomai-2.6.0 default examples such as latency:

robotlab@domain.hid$ sudo
./latency
/usr/src/xenomai-2.6.0/src/testsuite/latency/.libs/lt-latency: symbol
lookup error: /usr/src/xenomai-2.6.0/src/skins/native/.libs/libnative.so.3:
undefined symbol: xeno_current


Also I get errors in rtdm in xenomai-head examples  :

robotlab@domain.hid$
./tut01-skeleton-app
./tut01-skeleton-app: symbol lookup error: /usr/xenomai/lib/librtdm.so.1:
undefined symbol: xeno_bind_skin_opt

I get same error from my own application too,

*I am sure, my flags are correct !

The makefiles finds all rtdm and native *libraries or what else required..

So it is not a xeno-config fault. I also tried by hand and edited makefiles
properly.


My last option is recompilation of xenomai-2.6.0 and the kernel, then
reinstallation...


Can anybody help, what else can I try to solve the problem, my platform is
2.6.38.8-xenomai-2.6 ?


Regards..



Teoman.

Do you have the same problem if you run make install and run the
installed latency?

You are trying to compile xenomai-head examples with xenomai 2.6. This
will not work. You should try and compile xenomai 2.6 examples. Please
pick them from the git repository as the makefiles were broken in
xenomai 2.6.0 as well. Alternatively, you can apply the following patch:
http://git.xenomai.org/?p=xenomai-2.6.git;a=commitdiff;h=689e0433ab907958f162181d9b8c3b49012dd67a;hp=b10443b256dcc57a6a200572def4adda567d473a

It is the makefiles fault: the xeno-config usage has changed in xenomai
2.6. So, you should, as I already told you in three separate mails,
some of which even private, run xeno-config --help to understand the syntax.

The next time you ask the same question, you will either be flamed, or
simply ignored, depending on my mood at the time.
