#45210: Octave: unexpected termination after hitting ctrl-c (Octave v3.8.2, OSX10.9.5) ---------------------+------------------------- Reporter: mike@… | Owner: michaelld@… Type: defect | Status: closed Priority: Normal | Milestone: Component: ports | Version: 2.3.1 Resolution: fixed | Keywords: Port: octave | ---------------------+------------------------- Comment (by roberthuston@…): Yes, changing the octaverc file is what I did. When I plotted with "fltk" I kept getting a stream of errors like the following: octave-cli-3.8.2[34931] <Error>: CGContextFillRects: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update. octave-cli-3.8.2[34931] <Error>: CGContextMoveToPoint: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability.

I just did a reinstall and octave pulled down "fltk @1.3.3_0" but it behaves just like "fltk-devel @1.3.x-r10574_0" so I'll stay with gnuplot for now. Replying to [comment:95 michaelld@…]:

@roberthuston: Great (overall). +glgui is the default now; if you do not want to use fltk (-devel), you can install with -glgui, or you sudo edit the file "${prefix}/share/octave/site/m/startup/octaverc" and change the "graphics_toolkit" to be "gnuplot" instead of "fltk"). You might be able to create a ~/.octaverc file with "graphics_toolkit("gnuplot")" that overrides the "startup/octaverc" one ... I've never tried, but I'd guess it's an option.
