Ah indeed - not sure why ode is being so problematic, but we could make
it optional as it's not a big part of fluxus (although it is quite fun)...

I would next check for it in the library itself - eg:

$ nm /usr/lib/x86_64-linux-gnu/libode.a | grep ccdFirstDirDefault

nm: threading_pool_win.o: no symbols
                 U ccdFirstDirDefault
00000000000037b0 T ccdFirstDirDefault

The T means (according to
https://sourceware.org/binutils/docs/binutils/nm.html) that this is the
code for that function...

cheers,
