If i do fflush(stdout) inside the test function, the application
crashes. Also, no matter what i put in printf, it allways prints the
same characters, but it detects the \n correctly.. I don't see if this
can be related to the compiler..<br>

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..<br>

Is it including stdio.h? I have seen some targets where if you don't
the variable<br>
arguments stuff gets confused.<br>
<br>
Is the generated code warning free?

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

As long as it is compiled the same as the rest of the app, it should be
ok.

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.<br>

Right.<br>
<br>
Can you print from other tasks?<br>

Hi,<br>
<br>
I'm having trouble running an rtems application that uses code<br>
generated from matlab using autocode. It all goes well until a<br>
function of this library is called: printfs return awkward<br>
characters and then the application crashes.<br>
<br>
I have seen references to this before. Is this hard to do? Are<br>
there instructions?<br>
Standard glue code, etc.<br>
<br>
1) Is there any obvious reason to why printfs of the autocode<br>
generated functions are not working properly? They are<br>
compiled with sparc-rtems-gcc, as the main code.<br>
<br>
2) Are there any special flags needed to be passed to the<br>
compiler in order to link other libraries? Or some rtems<br>
configuration..<br>
<br>
Is there any chance it is printing floating point numbers from a<br>
non-FP task?<br>
<br>
<br>
Best,<br>
JM<br>
