[Octave-bug-tracker] [bug #31931] figure (1, "visible", "off") -> Bus error

[Ben Abbott]

Follow-up Comment #33, bug #31931 (project octave):

With the new changeset I see a crash when setting the menu bar.

I encountered a compile error with the changeset


DLD-FUNCTIONS/__init_fltk__.cc: In constructor 'plot_window::plot_window(int,
int, int, int, figure::properties&)':
DLD-FUNCTIONS/__init_fltk__.cc:730: error: expected `;' before ':' token
make[3]: *** [DLD-FUNCTIONS/DLD_FUNCTIONS___init_fltk___la-__init_fltk__.lo]
Error 1
make[2]: *** [all] Error 2
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2


After replacing the colon at the end of line 730 with a semicolon it
compiled.

I did not notice your request to try "figure(1,"menubar","figure")" for the
prior changeset. Trying it now I see ...
