Hi Robin,
Please keep the Octave mailing list in CC when communicating about
Octave issues.
Ok, then the problem might be another one (damn mpi!). Try the following:
Option a) Ubuntu 14.04 has a rather updated version of octave 3.8 if I
am not wrong. You can just install from apt-get.
Option b) If you want to compile from sources then
Recompile octave with configuration minimum flags. For example in
ubuntu 14.04 I compile with the following commands
./configure
CPPFLAGS=-I/usr/include/mpi make -j8
As you see nothing extra except telling make where to find mpi (check
if that is your path). Also the -j options tell make to compile using
y 8 cores, adjust to your hardware
With this configuration I have no problem with the dev version of
geomtry package (now without warning anymore).
If you really need JIT, then I can't help, cause I haven't managed to
get it to compile in Ubuntu 14.04.
Does this help?
