problem with RTAI

[brice BABAR]

Hello,
I try to test a simple application "hello world" to test RTAI3.1 ....
When I type "make" I get the following errors:


/lib/modules/2.6.8.1-adeos/build/include/linux/adeos.h:310: error: 
conflicting types for 'adeos_test_pipeline_from'
/lib/modules/2.6.8.1-adeos/build/include/linux/adeos.h:276: error: previous 
definition of 'adeos_test_pipeline_from' was here
/lib/modules/2.6.8.1-adeos/build/include/linux/adeos.h:317: error:

definition of 'adeos_test_and_stall_pipeline_from' was here
make: *** [hello.o] Erreur 1

What is the problem?
Are some modules missing?
Have someone any idea? Or an other simple program to test RTAI?

Thanks for help
