[Xenomai-help] Problem with RTDM

[Marco Rossi]

Hi every body. I have to test if xenomai support my multiport serial board 
with shared interrupt. To do this im using a program found at  
http://www.captain.at/xenomai-serial-port-example.php; when i run the 
program i get the error:
   relocation error: ./rt_serial_uprog: undefined symbol: rt_dev_read.
The version of Xenomai used is 2.2.4.

Thanks in advance

Matteo

Did you use the provided Makefile? It should like your application
against librtdm as required.

Hmm. What version is on the other PC? What else is different there? Can
you reproduce the same issue with this example (the template for Hannes'
page):

Hmm2: All I can say is that I tested with 2.2.0 and all worked fine.
Sorry, no time to test with 2.2.4...

Tanti saluti,

Ok. Take care to not mix up even more with RTAI, specifically kernel
patches...

I found the problem; in the same PC there is an installation of rtai and to 
avoid problem with dynamic library I modified the file /etc/profile adding 
the line "export LD_LIBRARY_PATH=/usr/realtime-rtai/lib"> Deleting this line 
all work ok.
Thank you for support
