It is just for our internal use,

We have code where third party device driver is written using RTAI as kernel
module
bu application is written as user space program. RTAI does not enable us
to use both user space hard real-time and kernel space hard real-time program 
at the same time. User space program without RTAI is slower the is our maximal
tolerance therefor we need to port application as kernel module to use RTAI.

Kernel builder is unable to original program due to missing symbols form, C++
library even when we finished all our ideas to dismiss these symbols.
Therefor we are looking to tool that helps us to find out our misstakes, yet


I look forward hearing form you

Yours faithfully

An automated C++ to C translation tool would most likely not help with such a
thing, as it would aim to produce semantically equivalent code and therefore
miss the same symbols.  If your code is restricted to the Embedded C++ subset,
then it should have no dependencies on the C++ runtime and so be suitable for
use in a kernel.  Perhaps you can list the missing symbols?
