Hi ,

I am trying to run an application in Xenomai 3.0.4 that was previously running
fine in Xenomai 3.0.2.

On startup of the application, I get the message:
./my_app: symbol lookup error: ./my_app: undefined symbol: __wrap_malloc

(which terminates the application.)

I noticed that malloc and free are missing from the cobalt.wrappers in 3.0.4.
They are now in "modechk.wrappers"

I saw that a xeno-config option was added (--no-mode-check/--mode-check) .
I have added this to my link flags for the application. I have tried
both options
and I still get the same undefined symbol message on startup.

Can someone please tell me how I can build the application to now find
these wrappers? Does it require a Xenomai kernel configuration option to
be selected as well?


Thanks in advance!
