Looking further, I think this issue is very likely an Octave one. For
example, the above virtual command occurs in the following context
in my version of the generated
/bindings/octave/plplot_octaveOCTAVE_wrap.cxx
#if OCTAVE_API_VERSION_NUMBER >= 40
virtual octave_map map_value() const {
return octave_map();
}
#else
virtual Octave_map map_value() const {
return Octave_map();
}
#endif
As you appear to be already aware, this is C++ code generated by swig and not
by any of our
typemaps in bindings/octave/plplot_octaveOCTAVE_wrap.cxx so your first
reaction that it is a swig issue is understandable. But note above
that the capitalized version which causes the issue above, i.e.,
virtual Octave_map map_value() const {
is meant to be used only for very old octave versions. For example,
I get the following result on my system:
irwin@raven> find /usr/include/octave-* -type f |xargs grep \
OCTAVE_API_VERSION_NUMBER
/usr/include/octave-3.6.2/octave/version.h:#define OCTAVE_API_VERSION_NUMBER 48
Please try the same command on Fedora. I am pretty sure you will find
that the issue is that octave-3.8.0 has failed to define
OCTAVE_API_VERSION_NUMBER at all (or else used an incorrect low number)
which would be a serious octave-3.8.0 bug.
Note my incoming e-mail has been disrupted again today by my
University service provider so if you or Andrew have already come to
similar conclusions, I haven't had a chance to see them yet.
