Hi Alonso,

can you please take a look at the generated file (paparazzi/var/Microjet/generated/modules.h) with the preprocessing errors?

Seems this is not correctly generated in your case and contains some error messages from the DTD or so...

The debian maintainers of xml-light patched it so it doesn't barf DTD traces into the output, I think this is the problem you are seeing.

How did you install the ocaml xml-light library? Is that a binary package already available from Mandriva?

I actually added the same patch to the OCaml Package Manager (opam) some time ago:

https://github.com/OCamlPro/opam-repository/blob/master/packages/xml-light.2.2/files/fix_dtd_trace.patch

So you could either install xml-light via opam as well or patch it yourself if you installed from the "official" sources.

Cheers, Felix

Hello Felix. I upgraded ocaml and some other libraries and now I get a clean make of paparazzi. However when building inside of the Paparazzi Center I get errors like

Hi Alonso,

Since you are using v5.0 it shouldn't try to build input2ivy in custom
mode... removing the function calls that are not found will of course
render the joystick interface unusable.

This might have something to do with your OCaml version.
Can you please provide some more details about your system?

ocamlc -version
uname -a

And post the full verbose build output of joystick:
cd sw/ground_segment/joystick
make clean
make Q=''

Cheers, Felix
