don't know about the integration into PdX.
i have used the MotionPlus successfully in an installation with 6 wiis
in parallel.

why use makefile.org? is something wrong wrong with Makefile?

not sure whether i fully understand.
you will need to find the headers (m_pd.h; cwiid.h) and the libraries
(libcwiid.so)

is it possible to properly install libcwiid "properly" (make install)?

which version of libcwiid are you using?

you should use at least the version from svn for the MotionPlus)
(though there are problems with >2 wiis with that. flo has a hacked
version of cwiid for that)

it's more like an incomatible header file...

shouldn't matter here.

yes

it's not "I" but "-I"
the compiler takes arguments like "-I/path/to/more/headers" to add more
search paths for include files (the linker uses "-L/path/to/more/libraries")

so the makefile often looks like:
PD_PATH=/opt/sw/pure-data/pd
CFLAGS="-I$(PD_PATH)/src"

(which will expand to the CompilerFLAGS "-I/opt/sw/pure-data/pd/src",
effectively adding the path to the directories searched for e.g. "m_pd.h")

if the m_pd.h in /usr/include and /opt/... is the same and the cwiid.h
in /usr/local/... and /opt/... are the same, you shouldn't need to set
any special paths.


well, this doesn't help you much since i'm saying that everything should
work but it doesn't...but you really should use an svn version of
libcwiid: http://abstrakraft.org/cwiid/svn/trunk)
attached is a patch against cwiid (rev201) that adds multiresolution
MotionPlus data.
in this case i also created a Make.local (for the external), containing
<snip>
PD_INCLUDE += -DHAVE_CWIID_MOTIONPLUS_LOWSPEED
</snip>
