I forgot to include
#include
for some strange reason it was no problem when compiling against the
corba-disabled version of orocos-rtt

Probably. You should define ORO_main yourself, it will never be in RTT.
Or maybe you forgot to pass the correct arguments?
ps. @peter There appears to be an answer without a question in the faq.
Q:
The first message I get is 'LXRT NOT INITIALISED IN THIS THREAD
pid=1234, BUT TRIES TO INVOKE LXRT FUNCTION >>rtos_mutex_init<<
ANYWAY'. What did I do wrong ?
A:
You tried to use RTAI's functions while RTAI was not yet initialised.
This happens if you use global objects which contain Mutexes. Examples
are Event and some DataObjects, Buffers and the Logger class. The
solution is not to use global objects, but use global pointers and
create the objects in ORO_main() with new.
A:
You did not put your program in the ORO_main() function. ( see The
Installation Manual and The Orocos OS Manual. )
