obviously from experimental support for the wii balance, which seems to
not be supported by the libcwiid used.

i have to admit that i never tried the git version.
no i have and it worked out of the box (no need for patching as the
patch is already included)

NEVER EVER do that.
this is why we have makefiles and CFLAGS and things like that: to set
the path where to search for header-files and libraries.
for unknown reasons only people who want to hardcode paths into #include
seem to compile the wiimote external.

i know that there is no documentation, but anyhow:
"make install" the libcwiid: it should install the headers and library
files into /usr/local
these paths should automatically be searched by any standard compiler,
so you just go on with:


anyhow, there is one thing missing which you cannot know (though your
problems are not related to that):
you have to manually tell, that you want the wiimotionplus to report
dual-acceleration:
create and edit a file "Make.local" and add the line
<snip>
CFLAGS += -DHAVE_CWIID_MOTIONPLUS_LOWSPEED
</snip>
to it.
(this is for historic reasons when i did not care to write a configure
script and libcwiid did not have the dualspeed feature built in)

well, why not directly start pd from where you are until the object works?
