rtems with matlab autocode problems

Hi,

No, autocode requires the real-time workbench only, it is quite
straightforward to generate the code.

I didn't fully understood your question. Anyway, i have tried to compile the
application with gcc and runs fine on linux so it should run on rtems with
the apropriate modifications. However, when i printf("test\n") within the
library finction, it returns strange characters, which doesn't happen in the
function that calls the library function..

I suspect of a compilation flag/option i may be missing on the library. Do
you have any idea?

Also, i don't need any rtems primitives/configurations on the library
functions right? I'm assuimng It is enough to have the rtems configuration
on the "main" file.


Best,
JM
